Unhappy coral?

Mainly I think because it's a ZOA in trouble.
I'm not guessing. He's using a kessel 160 it's not much punch an I bet there's no light meter. If it's being set by eye it's being set wrong. No alk test is as bad as no lux meter. Until your old and see your corraline change If the op is doing even vaguely regular WC the alk is probably ok.really no mater what salt is being used. Esp in a 20 g. Like all of us we put in too much Po and don't take it out. Well. And even that won't kill a ZOA until the cyano starts to out compete it for Po or smother it. Or the Po gets too high and it's just plain poison.
So chill. And help the op out.

I am running a Fluval Aquaclear 50 HOB with sponge and 2x biomax. With 4 fish and a small amount of coral in a 20 high, I am not using carbon or a skimmer at this point. Should I be?

Skimmer would be good but you can put a nylon bag of gfo that you can get at a lfs run it in your filter for now and clear up that algae no corals like any algae at all.

I'll pick up a the additional test kit for reefs soon for sure, I know I should be monitoring those parameters as well.

I'll move the frag to the top of the tank and and tweak the lighting a bit to see how it likes it.

Will too much flow adversly affect Zoas? With such a small tank size, a single powerhead is definitely moving water so the flow is pretty solid everywhere in the tank. I don't know if there is a such thing as "too much flow" for certain corals, as in enough flow to aggravate and cause a coral to close.

Thanks for the advice guys, much appreciated.

Jet is correct on light. It's for the coral. You can tweak the color for taste and intensity too but at a point it won't work well esp when you get an animal that just plain needs more. We do. Commonly even thought we spend big buck on it. Seem to forget is photosynthetic. It needs what it needs to do that. And personally I really don't like the single source over the tank thing cuz it bright to my eyes in my house. But because I've used light meters I know it's not that bright my eyes are lying to me the meter never does.
So yea Zoas like what they like for flow med is laminar is turbulent ish. And it's been my experience a ZOA will close quicker and be grumpy about flow over light. To much it too little. But to little first oddly.
So sprinkle some food it baste the rock and watch your flow and take you best guess like we all do higher up in the tank.
And maybe just maybe turn up the intensity One or two percent. Just for giggles. And don't touch it for three days. See what you think.
If you want to get crazy creep doing it every five days and see if you even notice. I bet you do. Then don't then do. All in the same day and will check even thogh you haven't touched it. Like my house every day.
 
How did I pick a fight by telling someone it's wrong to tell a beginner they don't need test kit for ALK mag and cal please tell me or show me where I was impolite please ?

Because the main issue here is what needs to be cared for and a test for as little as he has is not necessary.

Wow so then let me tell you sorry for telling you that it is wrong to tell the op he don't need test kits to test ALK cal and mag.

If he had a bigger tank with more corals I would not say that but you have to look at the situation and evaluate the problem and the fix.
 
Guys, as with any hobby we all have our experiences as to what works and what doesn't, but can we stop the ticking match? Geez!

You all make valid points regarding light, testing parameters and what not. I only posted because this particular Zoa is very unhappy, and it happened suddenly. The other zoas and the other corals are thriving under my current light setting. Nearly zero nitrate and dosing calcium (even if not needed at this point) along with a solid light for a small aquarium have seemed to make for happy corals so far. Well. Except for the little frag we are discussing. I did not add a clean up crew before fish because there was zero algae when I put the fish in. I needed to get something in the tank because after the cycle I was sick of looking at a empty aqarium. I went to the LFS to pick up a CC and was advised to put fish in the tank first to get things going, rather than starve a CC. I would not say I rushed anything in the process, other than not having all the test kits needed for reefs. I only have 4 small corals in the tank, so I did not jump in the deep end head first.

Bro you win I'm done I don't want to be called impolite for stating the facts this convo is not for I. I hope the op gets the help he needs.

Little gfo and you be good to go.
 
Just one other note cut the water changes to 5 percent a month because no sooner than the tank gets back to normal you change it again. See the effect and if you don't like it go back.

I'll keep that in mind. Thanks for the help guys. I moved the frag to the top of the tank and tuned the Kessil up a pinch, both in white spectrum and intensity. We'll see how it reacts in the coming days.
 
Any recommendations on a favorite GFO brand? BRS is usually my go to, they have their own branded GFO.
