Zoos shrinking

[Gaby_scan]

Hi everyone, I have been having this problem with some of my frags. I had a Dino outbreak and tear down the Tank, after starting it again Dino’s have been beaten, that was like a little over a month ago, now the tank is running ok but my zoas are not thriving and are shrinking. Can anyone help me understand why? I thought they were having too much light so I lower the intensity but nothing seems to be working.

parameters are normal including my nitrates at 5ppm and phosphate at 0.003 as of today.

you can give them a carbon peroxide dip and make sure the plug is clean as well. if you have iodine you can dip them in that the next day then keep them in low flow/medium light and give them some time to recover

Pictures? What do you mean by shrinking? Like losing polyps?

How are other corals? Any LPS doing well? You meant 0.03 PO4, right? What test kit. Sounds like your PO4 was too low for some time.

I'll take a couple of pics, my other corals are just fine, i have a couple of hairy mushrooms and a colt and they doing good. The zoas are the ones i'm having trouble with. Yes po4 was 0.03 i checked today and is 0.07 i have been dosing po4 to balance nutrients. Still zoas look like they are getting smaller and some losing polyps.

Moderate light and water flow (assure theyre getting some flow. Placement is best at lower half of tank

salinity 1.025
temp 77-79
ph 8.1-8.3
nitrate < .04
phos < .04
ammonia < .03

A little iodine and iron to tank water is favorable for them
