Thanks again for the content!!

I like how you kept the tank simple, not to many gadgets or upgrades..

I have found my Euphyllia close up a bit when my Calcium and or magnesium go low. With low Alk I'm guessing the Calcium was low in turn. I hope you get it straighten out! Nice Tank, great channel!

My frog did the same thing when I added fusion 1 and 2 to my tank….the only coral to react negatively. I did2 water changes (10 percent) in a 5 day period and now it’s looking great!

I would never disturb the sand bed, and I have best luck doing water change maybe every 6 months.

Yep continue your weekly water changes. I have a same tank. It will & does make a difference. 👍🏾

hi what filter pads is that?

Looks like lots of large vermatid snails near and around the frogspawn that will irritate them as well, they look large enough to break off and remove from the tank

I've lost a few torches in my fluval as well. I monitor the magnesium & alkalinity religiously now. Monitor those levels along with your weekly water changes & see if that helps over the next few months. Pay attention to your temp. as well. (I believe high nitrates also harm torches over the long term.) Consistency is king.

From running a simillar setup i had some good results in adding a nano tunze skimmer, lights were brighter with the fluval marine 3, and it still felt only enough par for lps. I believe your low on par so i would move the torches a bit higher and goto 30÷ water changes once every two weeks or 20÷ every week or so. And empty the tank once a year for a good sandbed clean. Stuff builds up fast and thats where it spirals out of control from doing okisch to real bad in only a few weeks.

I would check the calcium level, and track that, which directly affects your alkanaity. with torches once they shrink its very hard to save them - literally. did you increase your light Par suddenyl as well ?

Looks like there may be a bit too much flow? Since you don't have a variation in flow, the torch could be pounded constantly with flow.. Just a thought🙂

Are ypu using r/o water .im not a fan of reef crystal but when you mix youre salt is below 8.0 do you properly dissolved the salt mix . You should be doing smaller water changes every day like 2 cups since a small tank . Put some crush coral in youre media basket .possible change you salt mix

Love the videos, I’m struggling with my evo 13.5, had it up for a year and algae issues and quality issues overall, I’ve tried a bit of everything - gems will be next to add, could we get a video specifically showing what you have in each chamber basket set up, filter floss, what’s in the bags etc and in which chamber , how bout an email address to ask questions?

The light is not enough I have the same and most of the corals I had were dying you got to change your light or they’ll keep dying

raise your mag to at least 1500 trust me. they love High MAG.

To much flow same thing happened to mine I moved it to a lower flow area and it sorted it right out. Also have you raised your mag they like higher mag levels

just saying parameters are ok, doesnt mean they're ok. always good for us to see what your numbers are to really help. Fuzzy stick is a Birds Nest (seriatopora). No, duncans arent eyphyllia ;)

Your light looks white not blue. Did you change it out? Looks great

Lights flow

high mag is always a plus for eupyhilia. I like mine at 1500

I own torch corals. They are one of the more delicate SPS corals out there, even more than Frog Spawn or even Hammer Corals. I think you answered your own question. Alkalinity shifts (or any drastic spike in water parameters) will kill off heads, if not the entire coral in itself. You mentioned you don't test Alkalinity, and you really should. Here's why: Reef Crystals ( I use them myself) have a really high alkalinity of 12.5 dKh. So the problem with that, is that if your tank is running a low dKh, say 7.0 and you do even a moderate water change of 35%, you are shooting your dKh from 7.0 to 9.0 or more and that can stress your corals out to the point of losing more sensitive species. That is the big downside of Reef Crystals. If you are going to use it, be sure your parameters are close if you plan to do a decent size water change. Unfortunately, in a small tank like the Evo you own, they are much more difficult to keep corals in vs. a large tank. You probably have less than 10 gallons of actual water in the tank, so even taking out 3 gallons, can be a big swing in water parameters to your corals. I have more respect to someone that can keep a coral tank thriving in a tank that size, vs. a large one, you have to be more skilled at what you are doing, esp. if you are keeping LPS and SPS corals in it. Always think of corals like old people (like myself), they don't like change! lol. Sorry to babble on so long. Good luck!

Where to get the filter stack that you used? How do i search it?

I've found my flival evo 13.5 to be a very touchy aquarium, it's too small. Instable, it's hard to get corals to grow properly in small tanks if you've got too many fish ( my situation)

Would u recommend 1-2 small fish in 13.5 gallons? Or am I asking for trouble

Magnesium! Low mag will do that, raise that to 1500-1800 and you'll see a big difference

Are these tanks good enough for pulsing Xenia? I want to keep it stock as I find when people add different lights and other equipment it looks incredibly tacky.

Would you recommend this tank?

Is the tank better then the Biocube?

alkalinity is the most important parametrer by far for hard corals. theres really no need to test for anything else. just do a water change if things look unhappy. thats all you can do about high nutrients, so why even test?

Infestation of aptasia will be a massive problem! !!!

Alk is the only thing I test. And most corals hate a Alk swing, some just deal with it better Have you thought about dosing All For Reef? That’s what I do.

It’s the spectrum of light need more blue & red light

I have one of these tank same Fluval Evo 13.5gallon it's the lighting it's hot and close the the water tap try rasing the lighting I've been there know I'm better at this hobby and my tank is doing 👍 👌 I'm on my second tank 😀

عالی برادر❤❤❤❤

Title is misleading about the tank.

Alc 9 plus and high mag plus 1400
