I just finished treating my tank for ich. I used NOX-ICH and only lost 4out of5 clown loaches.R.I.P . I also ended up with a case of fungus I am treating with maracyn.My water parameters are good except my Ph is 7.6. My 3 sharks are showing no signs of fungus but are staying in a group and are not very active. I am hoping they are just stressed and will come around. Any ideas would be greatly appreciated. Ive had them for 7mths and they doubled in size. Reason for the ich is my heater died and the temp dropped to 62. I bought a new heater and got the temp to 80.
