I posted this in the zoa forum too, hope that's cool....
I have noticed that over the last few months, a few of my SPS were slightly browning, yet still showing excellent polyp extension, and I started taking steps to get their color back. Those steps included increasing my lighting (even though I believe the lighting I had before was sufficient) as well as running PhosBan in my sump. My water parameters were very good prior to adding PhosBan. Well, the colors have slowly but surely started coming back. However, a few of my zoanthid colonies have been suffering, apparently as a result of these steps.
I tend to think it's the PhosBan possibly making my water "too clean". The reasons I think this may be the case is because the algae in my algae turf scrubber has basically stopped growing, even receding. Also, the chaeto in my sump, while still very healthly looking, has also stopped growing.
I was testing zero on Salifert phosphates prior to adding PhosBan, but most salty veterans on this board have indicated that it's impossible to know your phosphate levels w/o using a meter like Hanna.
While I'm happy with the return of color to my SPS, it's tough to see my zoas suffering as a result. I guess it's possible that the additional lighting is what's bringing back the color in my SPS, but it's hard to say.
I'm leaning toward removing the PhosBan from my system to see what happens, but I'd appreciate any thoughts or shared experiences on this subject.
Thanks
