I have a 55l zoa dominated tank, friday I added a phosphate/nitrate remover sponge to the rear sump as the PO4 was 1ppm and NO3 5ppm, within hours every single zoa is closed up tight and not opened back up again.
What should I do? Is it a reaction to the phosphate/nitrate being ripped out to fast it's now absolutely undetectable? We are talking £100s of worth of zoa shut up tight and looking almost dehydrated!
There is a mushroom, few Xenia and gsp looking wonderful and my frogfish is happy as can be, but the zoa are really unhappy!
