So update: the peroxide only seemed to tick off my SPS so I stopped dosing. Adding the fuzzy chitons didn't work because my copperband still managed to eat them somehow. The money cowries originally aren't doing much for it either. However I started babysitting @Ayman 's purple urchin and it...
Looks like foramiferans (which is funny I never see these anymore). Maybe do one more soak in fresh then start them in water change water for another week. I know some people just toss outside rocks right in but you never know if they sprayed insecticides or anything outside.
Missed this. So I've read online that anecdotally they provide lots of anaerobic space for bacteria to grow and do denitrification. My current tank with 4 blocks was running a deficit for months until I started ammonium dosing. Never had that happen before in any of my systems. It's either that...
Definitely start them off with some nori. Mine have reached the nothing left to eat stage in my smaller tank and they can wipe out a quarter sheet in one evening now.
Usually the average online price of the coral is one of the main indicators, or how common they are within the club. Feel free to include things that you know are higher $ amount or not commonly seen onto the sheet.
