This video was really awesome for me. I have a reefing style/goal that is really similar to Josh’s so I’ve really latched onto learning everything I can from him! This reef will be my first tank ever on kalk. The kalk reactor just makes sense to me! Thanks WWC for making these videos happen. Thank you Josh for telling it how it is and making it easy!!

Best reef video I’ve seen. Really emphasises the need for testing. As he said, if you don’t test something bad will happen.

Kalkwaser is awesome I started using it because of Vik on his tank build. Ive seen awesome results on the aquarium! Thanks Vik and Josh!

Excellent video. Thank you

Josh, You are an awesome dude ! I admire Your approach to explain stuff. Great video !

Well done! I loved this simple focused and realistic breakdown! I hope you do the same thing with the other key elements.

A simple and well laid out explanation, thank you josh

Fantastic video, I cannot begin to thank you guys and josh on how much I liked this video. Perfect in depth explanation. Most KZfaq videos in reefing right now dont have any good info like this. Please do more of this

Great tutorial Josh

Absolutely great video, I’m going to go back to kalk, currently using SC 2 part.

Very well done and informative. I really liked how you showed the same principle at various scales. How a 2000 gallon system work and how a 75 gallon system work is the same in principle, but the tools change, the scale changes, and sometimes the actual methodology changes. Being able to show both a commercial scale and a hobby scale with the same principle is extremely informative. On a personal note, I love my IceCap Kalk stir. Though I do wish the outlet was a bit larger on it.

Thank you Josh , I just started with kalkwasser , I was nervous but feel better about dosing . Also the way you explain on how to make adjustments is straightforward. I always test so that is not a problem . Hopefully this will help getting my corals to color up and flourish.

Amazing video, it would be nice to see a guide on how to properly calculate the amount of kalk for nano tanks. 🙏🏼👍

Great video! I would love to see some videos where you help new reefers who are struggling with their tanks and show updates as they become more comfortable with the hobby!

Excellent content, I got a lot out of this

Awesome!

Well done Josh in driving the point home on how important keeping your alkalinity stable is.

Terrific advice!

Great stuff Josh 👍🏻👌🏼 team kalk for the win 🙏🏼

Thanks for another informative video.

Great video !

This looks like it's going to be an awesome series! Keep 'em coming!! ❤ One thing I need help with right now is installing a UV sterilizer. 😒

Great video

Josh is the best at explaining things very well to new and experienced hobbyist. I run Kalk via a 30 gallon sealed container with a versa pump and dose 10000ML per day to maintain my Alk. Eventually it will max out and then I will go to doser or Calcium reactor but until that time I get a great boost to my PH and for the cost it can't be beat.

Great video. I’m about to start dosing AFR for a smaller amount of baby coral. Two torches, a hammer, a candy cane and some mushrooms. I also have a crocea clam. So I’ll be using AFR to work this out. I do have Kalk+ 2 but have been scared to use it with a lot of reading of overdosing.

Great series 🙌👏✌️

Thanks for the information. I definitely shoudl be adding some more components like A, B and C . One thing I alwasy make sure is my salinity is good weekly. Having LPS and SPS corals, gotta be careful. lol

អគុណសាធូ❤❤❤☺️🌷

videos on different coral placement would be sweet

You talk like a pro brother 👏🏻👏🏻👏🏻👏🏻 nice video

we do the exact same thing !! make daily in 40 gallon closed vat ! dosed with industrial stenner doser

Loved this video with great information from the one and only Josh! I wanted to get your guy's thoughts as well as everyone else here on the channel. When you guys dose Kalk in your ATO reservoir, the thick sludge of Kalk that sits on the bottom builds up. It doesn't absorb in the water. What do you do with it? Suck it out with a pump or just leave it? Also where is your return pump located for your ATO? Because mine is sitting down in the bottom of my ATO in that sludge of Kalk, so is it dumping a ton of concentrated Kalk water back into my system? Hope this makes sense and I appreciate everyone's thoughts.

Using kalkwasser and balling is really the best solution for high end tanks

Great video! Been thinking of trying Kalk. How did you figure out what your evap rate was to know how much fluid you could dose? Doesn't the amount change from Summer to Winter months?

Hi. Love the videos. I know you guys have covered nearly everything there is to cover but youve said before you can tell a tank is doing well by the look off the corals. Any chance of a video to explain what you look for in the corals. Growth.. ( what to expect a corals growth rate would be expected to be in a healthy reef from different corals) and colour etc. Ive understood your videos but can only compare coral growth too previous growth. Thanks.

I've been struggling with PH for years, at night it would drop to 7.6 and throughout the day it would get to 7.85, just started using an ATO and after adding kalkwasser in it i'm at 8 and could not be happier!

👍 Explained very well. This helped me make a decision on a method to dose kalk with ATO. Thanks!

A vid of trace elements would be nice

I have been struggling with Alkalinity. Thank you for the video.

Limewater is amazing! it covers evaporation, alkalinity, calcium, and pH.

dude this is really helpful, ive had problems with anything growing for years while testing and dosing calcium, mag, and alk. All in a 15 gal system with no luck. All of my coral ended up dead

triton's core 7 keeps alk stable like a rock.

How often do you change the tubing on the versa& are you using the regular versa tubing or another tubing thx

Geo’s Reef has a nice KalkRx

This is excellent information and advice from a successful commercial operation. They are literally putting their money where there mouth is.

សាធូអគុណ❤😂😢🎉

How about one on lighting for looks with anemone? Finding that sweet spot with PAR, but also allowing the colors to pop.

Great video Josh! I thought you guys used Two Little Fishies Kalk?

I have found mixing at max Saturation to be an easy solution for me. I mix a 17g airtight dogfood container with RODI eyeball around 3/4cup of kalk powder dump it in & give it a good mix I then let it settle this usually lasts around 2 weeks at 4ml a minute. I like this because I am not concerned with adding too much or too little Kalk, I also dont stress over remixing what kalk powder was left over from the last batch on the bottom. I haven't really noticed a drop off in alk concentration over a 2 week period not sure if that has to do with the container being airtight and lack of perception.

All for Reef is perfect for smaller tanks.

This was a great video Josh! I'm currently dosing kalk from a 5g container with a kamoer pump direct to my RS170. I dose that during lights out and All for Reef during the light period. This has me thinking I should be dosing the kalk a bit faster than the 1.3ml/h I am. Thoughts?

How do you calculate your evaporation rate? I would hate to overfill my tank! Also this type of video rocks.

I'm a kalk fan as well. I mix 1/3 cup per 2000ml stored in a 5-liter reservoir. I have a cheap, $11 timed powerhead in the reservoir at night (when the PH falls) and a Neptune PH-probe actives a peristaltic at a 5-second runtime (then 5-mins Off) into the overflow on a Red Sea 165. Water top-off done by other means. So in short, I use 100% of the kalk as a slow-drip-slurry on demand at night only. No prblms. PH is 8.1-8.2 and Alk is 8.3-8.7 Very reassuring video presentation here... Thank you for helping us. 🌴👌

What if I’m running Triton Method? Can you run Kalk when doing this?

So you don’t run a ATO like the tunze osmolator for replenishing fresh water, instead you use the versa drip? On my tank I have a container for my ATO water and a separate container where I dose kalk with my versa. I only dose 1.10mL/per minute because I don’t have many corals. How would I be able to figure out how much kalk to mix with my 5gal ATO bucket? Also doesn’t the tank evaporate different amounts everyday?

So I have a question. I currently have an 80 gallon system that I want to me a mixed reef SPS dominate. I have all systems in place, Avast Kalkstirrer pulling water from the ATO resevorior controlled by a Neptune DOS and Maintained by the Trident. I keep the PH of the reactor pegged at 12PH and know when it drops below 12 to add more Kalkwasser to the reactor. My question is what is the proper way to administer the kalkwasser. Josh says that they do a constant 25ml/min on their system. So was this determined by the evaporation rate of the tank? I think that is where I am confused. When I first set my system up, I took a gallon of water converted that to Milliliters/divided it in half and was using that as my starting dose from the Kalkstirrer. Sort of half evaporation from ATO and half from the Kalkstirrer. My Alk always seems to see creep up and I have the trident to set to shut off the stirrer if Alk in the tank goes above 9. So I am just not dialed in correctly with how much kalkwasser is beeing administered to the tank? Please help me understand what I might be doing wrong.

I was space limited so I went with auto dosing of red seas alkalinity which doesn’t require stirring So far it keeps my alk in the range I need at around 30 ml per day That gets expensive so I buy the big jugs

Where can you get those 30g extra tall glass tanks like under the farm systems? I’m local to you guys, I haven’t seen them around Orlando though. I need one for my new build!

Great thx…putting the kaulk in you return … how often do you have to buy pumps for the top off container…

Using a kalk stirrer how often do you recommend adding kalk, should you remove some powder from the bottom periodically?

can u do a video on BIonic dosing alk ?

Josh you are a reefing hero! Could listen to your knowledge for Hours! I have a question… I’m thinking of starting to use kalk. I have a 20 gallon mixed reef and would like the benefits of increased PH from kalk. I’ve heard using kalk in ATO is a bad idea as it creates an inconsistent PH level due to changes in evaporation due to variables out of my control. (Room temp, humidity) Have you found any issues in using kalk in a ATO for a smaller tanks? I planned to run my ATO as normal and start dosing kalk on a doser at as close to evaporation consumption as possible, along with the coral essentials 2/3 part. Would u keep it simple and using in ATO and risk the slight PH inconsistency Or dial it in with a doser?

Would you ever have the need to dose kalkwasser on a fish only system? Thanks

Is 9.4 alk good

it is my goal to have vic come review my tank one day.

Balling method wouldn,t work with the Kalkwasser additive?

Can you add other supplements to the kalk top off water. Ie: Iodide, mag etc

I have a 4 ft tank how much kaulk would I have to use in my top off off starting off.. I dose triton about 2.5 mil a day LPS they don’t need much I guess.. would they benefit from the switch to kaulk

What Alk level do you target at WWC?

I dont use so much kalk to make full saturated solution , still always have white dust on the bottom :/ why ? If I give RO and stir it will it dissolve ? Ty dor the answer I love your videos guys

WWC has given away one of their secrets! Kalk for 99.9% of their tanks including the nanos 🤯

I use all for reef I dose 15ml everyday at night and test once per week now I’m wondering if doing this would benefit me more than all for reef

Doesnt the magnesium in the l Kalkwasser precipitate out as magnesium hydroxide? Making it pointless in the mix

What’s the name of that Orange/Red Rhodactis at 9:15???😊

Cheers Josh. I've been wondering at what point do I reach maximum saturation using all for reef in my ato (7gallons). I've gone from 100ml a week to 300ml a week in the last few months. Any thoughts???? besides calcium reactors, they scare me 😅😂

Put a pump in the ato bucket, boom. Cheap kalk stirring

What is the torchs name at 11 minutes flat?

Hello I am having trouble with my reef tank. I purchased beginner corals from you guys, but I am now sure that the nitrogen cycle did not complete, I have high nitrites and low ammonia, I am wondering if I should do a large water change or if I should leave it and dose seachem prime or similar products

What sand substrate are you using in the main display. Where the copper band is at ?

Please suggest a good brand for kalkwasser.

"When you fluff the bottom, it gets stiffer." 😂😂😂

So you add 6 grams per gallon of kalk for the size of the container or the whole water volume @worldwidecorals

Would a Trachyphyllia survive with 40-50 par?

I keep my DKH about 10 is that good I seen some coral deaths but I think it’s my light…

How do we determine the starting concentration? (In Grams per Gallon)

Hi josh what’s the phosphate level on your tank?

I didnt get it how long in advance the solution has to be mixed and also in what time used? I ve read that Calciumions fall apart whilst in contact with oxygen, thats why a kalkstirrer is in this point better?

How do you stop your calcium climbing too high. I'm balling and tried kalkwasser with it and the calcium went out of whack

What hammer is this at 15:51? Has WWC ever sold this one?

How do you know how much to kalk water to put in? I tried with the auto top off and it would just take the top off the water and let the top off pump put it in but my alk went through the roof! It was pumping just when it evaporated

So what if your system uses alkalinity but very little calcium? My tank is all softies. If I dosed Kalkwasser, I’m afraid my calcium would shoot sky high….

Also kalk is the cheapest way to maintain alk/ca in their huge systems that is the secret 😎

:11 budgie smuggler?

so you dose about 12000 ml of kalk a day?

Please more Info about the Office Tank. Light, skimmer.... Looks Hot. Kind regards from Germany

Kalk is totally impractical for most reefers with small to medium tanks. Your much better just using a good two part or even AFR on smaller tanks

Great video but the clicking in the background is too much, I'm bouncing!

Just a message to new reef aquarists. Josh is very experienced and he tests alkalinity weekly, less experienced people should be testing more often than that. I am a beginner and test alkalinity, salinity, and temperature daily, and other parameters weekly, I recommend this schedule to anyone starting out.

So wait, you dose 8.5ml per minute? So if there is 1,440 minutes per day, you dose 12,240mls per day? Wow.
