ok my tank is only a couple months old so im still suffering new tank syndrome but i cant figure this out. In the last 2 weeks ive lost a kole tang, 3 reef chromis and now a 3 stripe damsel. Only fish left in my tank are 2 clowns, desjardini sailfin, foxface, pink spot goby and lawnmower blenny. ive been doing water tests and it comes back maybe .05 amonia its somewhere between at max .05 and 0, 0 nitrate, 0 nitrite, 8.3 ph. Ive been getting cyano and a diatom bloom but all my tests are showing zero anybody got any ideas?
