I have two Aquatech 30-60 filters on my 55 gallon tank and the bio filters on the one filter system is getting built up with some debris. How should I clean the bio filters? Would regular tap water ruin the filter because of the chlorine?

NEVER WASH BIO MEDIA IN TAP WATER

Washing biological media in tap water can be a recipe for disaster. Chlorine can destroy your biological filter so always wash this type of media in existing tank water. The easiest thing to do is when you do a water change, just siphoned some off into a bucket news that to wash the media. You can save yourself a lot of hassle if you do this. I have read countless times about people washing their biological media to tap water and then next morning they wonder why their tank is completely clouded up.

i have an aquatech 30-60 on my tropical tank and as ofl said never wash the bio media in tap water. that being said i would consider changing your filters to aqua clear filters. there mechanical and biological filtration make them the best for the hob systems. you are also able to customise them to your needs(like more bio media). in my opinion if you plan on using your 55 for lifetime home for your oscar i would personally replace the 2 aquatechs for 1 aquaclear 110.
