My tank is 7 months old and I have had the same 2 anemones in there for the last 4: a red bubble tip and a black widow. They chose high spots and have pretty much stayed in the same place most of the time, moving in occasionally with in the same area as they have grown to get a deeper spot for their feet. I feed them pieces of shrimp once a week and about 6 weeks ago the red one spit. The splitters looked normal in about 2 weeks just mini versions of healthy specimens. The red bubbles stopped eating a two weeks ago and started shriveling. A few things happened about that same time decline of my two reds. My phosphates went to a high of 0.6 from every two weeks water changes and feeding twice a day. I added an HOB refuge and stocked with 6 jars of pods and Cheeto. Started using pho-E to slowly lower. I noticed quite a few tiny 1/8” to 1/4” Medusa worms popping up on the glass and researched how to remove. I guess they occur only when there is excessive detritus. They have no natural predators, and only plucking them or reducing detritus lowers population. I also read they release a poison if injured. I haven’t seen anything grow past 1/4” and those i pluck. I also added about 25 hermits red and blue leg as a clean up crew to deal with detritus and I added a bag of carbon. Hermits and snails all seem to be fine. I have had 2 sand sifting stars that have been fine for 4 months and still are great. My corals are fine and I have a mixed reef. The only one that looks bad is a Kelly green psammocora which came in from my 4 month quarantine coral frag tank with a little receding tissue and it has gotten slowly worse rather than better, despite my efforts. I have a 65gal Aoi and run 2 MP40’s turned down to 20%. All fish are fine. Two weeks ago one MP40 started rattling and I put an MP10 in its place on 100% for several days until my replacement came in. That’s when the anemones seemed to get really ticked. They moved to the back, got smaller and shriveled and the black widow moved way lower and even though its still good sized and eating, its arms are thinner. I have since replaced flow to original settings, slowly gotten phosphates down, went back to feeding once a day but they dont look much better. I really thought the high phosphates were the issue, but my acros and monti’s are fine. Bubble coral, acans, mushrooms, zooas all fine. If there is poison in there from dying Medusa worms how do i get that out. I read maybe GFO but I’ve heard of that killing stuff.
Ph 8.2 ( i really struggle to keep this over 8) the only way i slowly got it to this is with PH Boost+, it wants to be 7.8 or 7.9)

On a side note: the tank is 7 months old. Xr30 running 100% AB+ 8am to 8pm. I have a 15 gallon frag tank at work that i started at the same time with zero fish. It is growing tons coraline algae. It also has an XR30 at 60% 9am-5pm. My 65 still hasn’t grown any coraline algae yet. But, my the soft corals and chalices and favia are growing. It went through all the stages of algae, except I have never had cyano. My clean up crew keeps the rocks pretty clean, but when my phosphates were as high as they were I had to clean the glass 3 times a week with a light brown dusting (diamtoms)
Any help you can give me on helping me get my bubble tips back in to shape would be appreciated. Last 2 videos are my bubble tips former glory.
