Zoa help please

[knoxmandan]

I have a zoa dominant 80 gallon shallow rimless tank that was set up and cycled with 80lbs of dry rock from BRS in august 2016 also running BRS hi cap GFO in reactor. I stared the tank with new g3 radions and switched to 2 new kessil 360we running 10 hours a day a month ago hoping to fix my polyp problems with no change at all some open and most dont. Their not melting that i can see and some even have new polyps that have grown on to the rocks and barley open.I also do 12-15 gallon water changes weekly dose mg/alk/calcium my water test are done with new Red Sea test and Hanna checkers for alk/phosphates.
temp 78
salanity 35/1.026
nitrates 0
nitrites 0
ammonia 0
ph 8.3
mg 1400
alk 10.13
calcium 420-440
phosphates 0.08
I also have about 20 fish that i feed 3 cubes a day brine/mysis/and cyclops and a 1/4 sheet of seaweed a day 3 clams, 2 cleaner shrimp, 1 fire shrimp, 2 pistol shrimp, rbta ,scolly and 2 frogspawns
2 candycanes, 5 mushrooms,8 acans, 3 feather dusters 2 rock nems 100+ hermits and snails and other corals all seem to be doing fine.

What improvements could you do to remove the GFO reactor? I think it would be a great relief to the zoas.
What could you do to really change the light, if you think (or even know) that is the problem?
I'm not telling you that IS actually the problem, but want you to think!
Why did you change the LEDs for another LEDs?
I'm the only one here that will ask you these types of questions to try to solve your problems!
I can't see anything else's in the picture, but please note that your system is very young too.

Have you checked you light levels with a par or lux meter? I found I had my Kessil turned up too high based off of just my eye. I dialed it back to 45% intensity and everything is much happier.

That's a lot of fish in a short period of time and in a new tank. Are you running GFO due to nutrient/algae issues? The GFO seems a likely culprit to me too. It will strip the nutrients from the water and starve out the zoas.

I have several zoas and run gen 3 radions and they are doing fine. did the zoas come from led lights? may need to acclimate them to let might be too much for them but after the acclimation period should be fine. don't know much about the Kessel but the radions have an acclimation setting for this. also I've heard (not 100% sure) that they tend to like dirtier water. sounds like you feed quite a bit so you may have a nutrient rich tank which I also do. I have a 120 with 10 fish and feed twice a day. I don't dose anything but use coral pro and my zoas do well.
I also run biopellet reactor to help.

Im not even sure i need the gfo running now what is the acceptable phosphate level mine is 0.08? i added the gfo due to algae problems in the beginning after the cycle my tank went green with hair algae from the phosphates coming out of the dry rock.

I changed the lights because of the pain it was to make adjustments to the radions just didn't like them. I didn't really think they was the problem there just not user friendly.

Thanks i really appreciate that! I really do need help solving these problems.

I haven't checked the par because i dont have a meter(guess its time to get one), but i have been running it full blast 25% white 75% blues for a month now .This morning i dialed it back to about 75% and tomorrow i will cut it back to about 50% my tank is 48x24x16 and the lights are im guessing about 12" off the water.
I was running the gfo because of algae issues after the cycle now i am not sure i need it anymore because the algae is gone, I also have a 5 gallon hob refugium with chaeto running too. Im not sure i have nutrient issues could you help me understand what do you mean? are you refering to nitrates/Phosphates?

What is the best PAR for zoas? thanks

have you added any corals latley ? Maybe check for nudi's ? . Have you moved them around at all? Maybe flow ? I run my kessils 8 inches off the water and run full blue and full intensity for about 7 hrs a day and then dial them down over the night and lights go out at 11:00 my tank is 14t and my zoas are mostly near the top so I dont thnk they are getting to much .

That's probably your issue. That's a lot of light.
