Still having some issues with regard to my tank. Doing regular water changes ( taking a few gallons out and replacing 2 times a week), checking levels regularly. Heres the newest issue. Did 20% water change yesterday. Checked water source for Nitrite, Nitrate,and Amonia first. All at 0. or very close to that, added salt to water (instant ocean) specific gravity 1.024 ---perfect. All should be good. NOT..... Water with instant ocean salt now has Nitrite at .25 before putting into tank. Slight increase in amonia this a.m but still very low. I dont get it. I thought that this was supposed to reduce build ups not increase levels. Additional info. Moved rocks, cleaned under them cleaned substrate to remove debri (didnt find much there) checked filter and made sure no blockages (has great flow) my inverts seem to be fine moving around. I get it that i disturbed the tank so I expected that there would be a change. The Nitrite increase with the salt is my concern. No body is behaving abnormallly. have reduced feeding to minimum and I am removing any food I find. Any more suggestions? Tank not overstocked One Clown and scooter Blenny plus cleaning crew of snails,hermits,and 1 emerald crab.
