Frag Tank help

[Steeze]

Started a 20g frag tank because my 1 1/2yo 14g Bio was starting to get crowded... I cycled the tank for 5-6 weeks and my parameters are as follows:
Sal/Temp- 34/70*, Kh- 9.6, Cal.- 429, Mag- 1260, Ph- 8.4, Amm- .25, No3- 6, No3- 0, Po- .5
Light- Kessil a150 Ocean blue 8in from water lowered to 4hrs a day (until I can figure out what’s going on)
Seachem Tidal 55 HOB w/Matrix and cheipure blue
2 pumps, 1 on each end
Smart ATO
Coralife Skimmer (going to replace soon)

It’s been 2 weeks when I stocked it with frags. It was nice and puffy at first but now seems deflated... had to put the trumpet corals back into the DT and is now looking better. What am I doing wrong? Any insight is much appreciated.

Your ammonia is .25? That’s probably the problem.

I’ll do a big water change today, hopefully that’ll work. I was wondering if a simple HOB was the problem... never used one before so I was worried it could be that.

You need zero ammonia for corals. I'd do a large water change and add some bottled bacteria. The HOB filter should be fine.
