Haven't added salt since forever. Nitrates and nitrites are low--and there's only five fish in a 20 gallon tank--plus huge java fern(s) overtaking right side of tank. Haven't had water problems in a couple years, except the PH is impossible to raise unless this crap I bought sucks--it's Top Fin--other stuff I used before was better--at least got it up to 7.0.
Another issue, I have lost two fish lately-one danio and one mickey mouse platy-and I never found them. They are either lost in Java fern roots or--I don't know--can't find them. I looked everywhere !?! Did they dissolve? Were they eaten? If so, by who?
Sorry if I sound stupid. Like I said, the only thing I do right is raise black fin tetras.
OK to add sea salt, you think?
