Post-disease tank recovery

Post by finnley4 »

My tank just got over a nasty bout of Ich, and I'm not sure how to get things back to normal. Water params are good, 0 ammonia, 0 nitrite, 10 nitrate. Should I do anything special with the substrate or filter media?

Glad your tank's on the mend! I'd say keep up with small water changes, like 10% every few days, to help clear any leftover meds. What kind of fish you got in there? Some are more sensitive than others after treatment.

If you used copper-based meds, check your carbon filter. It's gonna absorb residual copper, but replace it after a week. Also, test your GH and KH, some meds can mess with those. What's your substrate? Sand holds onto meds longer than gravel.

Thanks for the tips. I've got a mix of Tetras and Corys, and the substrate is sand. Didn't think about the carbon filter, gonna swap that out tonight.

Nice, Corys are tough but Tetras can be sketchy post-treatment. Keep an eye on their gills, sometimes they get irritated. You using any stress coat?

Sand's tricky with meds. Stir it lightly during water changes to release any trapped stuff. Also, if you're running a sponge filter, squeeze it in old tank water to clean it without killing the bacteria. How often were you dosing?

Bacteria starter's a good call. Also, if your plants took a hit, trim the dead leaves so they don't rot and spike ammonia. What's your lighting schedule? Plants recover faster with consistent light, but not too intense.
