I am on the bigger island aka Long Island my water is pretty acidic. 50 percent water changes every other day that is insane what is in that tank? I got my one mud ball tank 65 gallons 4 Cories and 5 giant danios and 1 platy with my Favorite (and only) angelfish. I try and do water changes every week about 20 gallons I might need to pick it up cause I have been slacking recently. But yeah basically I got the tank as a gist to replace my smaller tank. But when I went shopping I bought weird pairings and now I got a really weird tank.What part of NY? I’m on the island with city water and my water is great . I change 50% on one tank every other day and on the other every 2 days. Once a week on community tanks. I go from the tap through an under counter filter than into the tanks. Nothing added. I do carry buckets when draining. I’ve got cherry shrimp with the discus so I’m always looking for the little ones that get siphoned out.
