So i jsut got antoehr 50 gallon tank for my larger dovii fry, my paretns wernt too happy saying they can smell all the water in the basement. My question is, is there a way to remove that moisture dampness smell? i ahve a 180, a 90, and now a 50, i do weekly water changes and monthly filter changes with carbon. Am i doing anything wrong? should i step up water changes?
