Couple of questions / comments. 1. Could you do a "how to" video on how to cycle a tank? When i recently started my first tank i checked my "go too" channel and it didnt look like you had done one. Apologies if you have and i didnt find it. 2. Has anyone had any success with Biohome media and its claim to produce nitrifying bacteria to break down the nitrates?

I’m a new fish keeper and understand the cycle through great videos like this but my question is. Do I just let the cycle happen or do I do partial water changes during this cycle ? I’ve been doing water changes but doesn’t seem to be cycling the tank which is a few months old now. Thanks in advance keep up the good work.

@MrMaru007 4 жыл бұрын

Hey Thomas.. I have a 35 gallon new Aquarium and it has been 3 weeks without a fish. Do I need to change water on weekly basis or the Aquarium will be automatically cycled in 4-6 weeks. I add some pelets every week. Awaiting your advise.☺️

@ericvickery1698 4 жыл бұрын

Ok so I need your help! I have a 65 gallon discus tank. Everything was going great and at month 8 my nitrates spiked to 20ppm. I believe it was from rinsing my media during a filter “change”. So far I’ve redone the inside of my canister adding more effective quality media & added a 3 pad sponge filter. I’ve also done 25% water changes every 2 weeks. I’ve stopped doing this the following: my local fish guy said to add Fluval Cycle after I did the water change but it (I believe ) is the reason my tank is super cloudy now. Can’t get rid of the cloudiness. Would you suggest going back to using cycle or no? Did it cause the cloudiness? Why can’t I get rid of cloudiness now? Canister size is large enough. Maybe I should add an above water filter too? If so, what kind? Thank you in advance!!!

Hi Thomas. This isn’t really related to this particular video but I NEED YOUR HELP! I’m a beginner fish owner and I’ve already learned SO much from you! But I’ve noticed my fish tank is so gross! It’s got a yellow tint to it and I’m afraid my fish will pass away because of it! I have 3 neon tetras and I’ve had them for about three or four months now. So when we first noticed this happening we did a bad move and took the fish out and dumped all the water and cleaned it all out. Later we learned from a fish store employee that’s not good and it’s unhealthy for the fish and can even kill them. So it was all clean and they were still alive which I was so happy about. Until I made a rookie mistake, ( leaving the light on 24/7 ) and algae grew everywhere! That’s when I fled to your channel. I cleared most of it up but my tank is still gross and I don’t know what to do! My budget is low and I don’t want to make the same mistake and dump the water all out but it’s all I can think of to do! Please help!

How long does it take to see nitrite reduction in the cycling process? I'm at the stage where I'm seeing Ammonia drop after 24 hours but it takes many days to see the nitrite drop. I'm doing a fishless cycle and want to know how long this is expected to last.

@dlee611 5 жыл бұрын

Is a 0.5 ppm ammonia and 0.5ppm nitrate too high? I’ve done water changes every other day and it still remains relatively the same. Nitrates are at around 20ppm. The tank is about 2 months. I have about 12 small fishes (tetra, gourami, mollies) in a 23 gallon tank. Should I be over concern at the moment to try and change water daily or should I wait for the nitrogen cycle to do its thing? I’m also feeding by hand...I have reduced feeding from twice a day to once a day.

currently cycling a 10G tank, has live plants and a rock cave i made with pvc elbow and rocks super glued to it. i admit i used a lot of glue, but it sat on a shelf for over a month. plopped it into my newly filled tank after soaking in conditioned water all night. And boom ammonia readings for 2 weeks, and now in week 3 skyrocketing nitrite and some nitrate. I'm baffled, i have done nothing but fill it, add a couple live plants and my rock cave. i removed it and 20hrs later 0 ammonia. did i really just start my cycle with super glue? 🤔🤷‍♀️ so every time it drops to 0 i put it back in lol till cycle is complete and fish can replace it. kinda upset i may not be able to use the cave if it's doing that to the water, i worked hard on that!

So what do u do if u have a let’s say a 30 gallon with a dwarf gourami and u want to add like 10 neon tetras should u add 2 wait 2 days add another 2 or so u put them all in at once as tetras don’t produce to much waste

What is beneficial bacteria? Are there different types of this stuff and would you therefore need 2?

@ironlungs10 5 жыл бұрын

I just set up a new tank with ADA soil. I kept the bacteria from my old tank alive in my filter by hanging it onto another tank while I took down and set up the new one. As ADA soil creates an ammonia spike in the first few weeks, will the bacteria in my filter stay alive in the meantime while this process starts?

@captainwin6333 5 жыл бұрын

Ammonia can exist in two states depending on pH. Ammonia NH3, which is toxic or Ammonium NH4 which isn't. For those with acid water aquariums, Ammonia NH3 isn't an issue because any Ammonia in the water will be Ammonium. It's people who have harder water with higher pH that really need to worry about Ammonia NH3. Here's a chart showing the percentage of Ammonia/Ammonium for all the pH range from 0pH to 14pH. answers.seneye.com/@api/deki/files/261/=NH3-NH4_equlibrium.PNG Toxic Ammonia NH3 is a big issue for Rift Lake Cichlid aquaria and marine tanks because at 8.3pH 18% of the Ammonia in your system is the toxic variety. At 6.8pH, zero percent of Ammonia in your system is the toxic variety. Regarding the NH3/NH4. A lot of people think those Seachem Ammonia alerts give erroneous readings. They don't. They only read NH3 Ammonia, not the NH4 Ammonium. Liquid test kits read total Ammonia, NH3 and NH4.

I just tested my 29 gallon aquarium. My ammonia is between 0 ppm - .25 ppm, my nitrite is between 2.0 pmm- 5.0 pmm, and nitrate is between 0 ppm - 5.0 ppm. I just did a water change but is there any reason my ammonia and nitrate would be much lower than my nitrate levels? How do I fix this?

I've got a 15 gallon 24 inch wide 12 inch height and depth Pretty heavily planted (50-60% maybe more)low tech aquarium. Was planning on putting about 15 neon tetra in it which would work with your 1 inch of fish per gallon. But i was also planning on putting anywhere from 10-20 red cherry shrimp and 2-3 mystery snails. Do inverts still apply to as an inch of fish? Do you think this would be too much? I realize the rule is more about the ammonia produced from waste and shrimp still produce waste. but things like snails eat that waste so how would this balance out, your thoughts?

@catzawadzski3748 5 жыл бұрын

You can easily do your plan. I would add the fish slowly over about six weeks in groups of three to five about two weeks apart. The shrimp can all go in at once do to adding very little bio-load.

How about adding tap water with a water conditioner straight into the tank? Is this harmful? Thanks Dave

@theallseeingeye9388 5 жыл бұрын

Best would be mix em up in a container and put an airstone in and let it air out for 2 or 3 days prior to use. There are new lines of thoughts on the effects water conditioner especially dechlorinator has on livestock especially after repeat exposure. Also if u have a planted tank its best not to add the conditioner directly into the tank. It tends to neutralise the micro nutrient components in the tank..
