Aussie LPS with Photosynthetic Gorgs problem

[ryanuy]

Hi guys!

I have a 200g frag tank with mostly Caribbean Photosynthetic Gorgs and some other corals. I keep soft corals (zoas, shrooms, etc), sps even and quite a few aussie LPS.

My big problem, are some of aussie LPS like acans, bowers, gold torches, and scolys. They are located in 2 totally separate portions of the tank and do not touch each other at all. I have other LPS lobo brains and plate corals that are totally fine. Zoas and soft corals all have good growth and are also fine. Even the SPS i have are all doing quite well and are growing.

Its the Aussie LPS that I have noticed somehow are not doing so well. The acans seem to be very slowy but very surely thinning. The scolys look stressed daily. The bowers I have also look stressed and seem to be very slowly thinning as well.

I have tested everything multiple times over the last few months. I have tested with ICP twice. All parameters are normal. I have tested with a PAR meter and the light levels are also all okay. Flow is okay as well (2 maxspect gyres). Other things I have tried to check very often are Nitrates, po4, alk, cal, mag I test very often and are all okay and well within normal parameters. I change carbon often as well and it doesnt seem to help at all.

Im all out of ideas and the only thing i can think of is that the carribean gorgs which are a majority of my frag tank are releasing some chemicals or toxins that are slowly killing the aussie stuff only? Is that even possible? The rest of the corals I have are really all totally fine. The frag tank has been running for 8 months in preparation for the main tank that is still being constructed so its not exactly a new tank.

I used to keep Scoly's.
They like super low flow and to be spot fed.

Do you feed your reef coral food to keep nutrients up within the water column?

Thanks, Freddie

Yes, i feed Red Sea Reef Energy daily and reef roids 3x a week.

Which lab preformed your ICP?

Read this:

"Photosynthetic gorgonians love light, so be sure to place them in an area of your tank where they will be under moderate to high lighting for several hours a day. Most gorgonians prefer to be placed upright, freestanding, and secured to a rock. Gorgonians can be damaged if they are leaning up against a glass wall or other hard surface that is impeding flow to their tissue. Even though photosynthetic gorgonians are fairly easy to keep, corals can sting and damage their tissue, so it’s best to keep them at a distance to prevent touching. In general, I have a rule of thumb for placing different species of corals in an aquarium. When placing the coral in the proper location it’s always wise to provide a few inches of space around the coral since they tend to be territorial in nature and can engage in chemical warfare."
