I'll try and keep this short. Had a very nice tank full of mainly softies, huge area covered by large green polyps. Various red and green mushrooms, cabbages, leathers etc. Had an out break of cyano, got that under control 5 spot goby helped a lot I think. Then came the obsession with parameters the same one I had for a while with my discus. Was put onto Nopox by a mate who swears by it..... I do now but completely unsuitable language for here lol. Yes, nitrate levels nose dived, phosphate barely detectable, but softies suffered massively from water I was advised was now "too clean". OK, I can understand that. Cut back on it from 10ml daily in 350ltr, now at 1ml daily. Can Nopox be used in a background dosing regime so to speak, or, as I'm planning, managing levels more naturally using macro algae (tmc reactor ordered). Also happy to use rowaphos or phosguard again. Oh, whilst I'm discussing parameters, is it worth using a fluidised sand reactor.? Thanks for looking.
