Hello and happy new year! I have a problem and i ask you for help. I have 90 gal
. tank <reef and couple fishes> My water parameters are; amonia-0, nitrite-0 nitrate-0 calcium-480, alkalinity-6 mq/l, magnesium-1280, Ph-8.2.I have many mushroms,zoas,acropora, montipora,galaxia,dorsea clam, xenia,hammer,brain. Today there is a problem. But today my stony corals < hammer, plate,bubble> are not good, they shrink and looks like they not happy and montipora has some spots like bleaching.I read on internet and maybe that is the problem. In my tank i have 6 inch toadstool leather and 3 small frags, 5 inch toadstool, 5 1 inch frags of soft leather coral, and 3 inch green nepthea leather coral. It is my fault that i did not check that before. I read that they sprey toxin into water sometime and that hurts other corals mostly stony corals which explains everything.<hammer, plate. bubble> You think that is the reason? Should i sell them and leave only one or two? Is this to much for 90 gal
. Or maybe there is something else? I know it is hard but please help. I checked my parameters and everything is the same exept nitrate -20. Is that toxins made my nitrate high? Please help!!!!!
