Alarming title I know, but here's the deal. I run several aquariums and i broke one down a few weeks ago when I redid the tank. I removed the canister filter and it sat dormant for a few weeks in the garage (still full of old tank water and media etc) I've just got around to starting to clean it after having a bunch of other aquarium projects going on. So I cracked open the top to begin cleaning it out, to say it stinks is a huge understatement. Most of the media within is very very dirty, i rinsed through everything a couple of times. I'm not planning on using the filter or media any time soon but want to get this thing cleaned. My main concern is the biomedia. What are you thoughts on using a water bleach mixture to clean everything up the rest of the way? Also what ratio will be best? I was thinking, bleach:water 1:10. I only have a tiny amount of white vinegar on hand and I don't think vinegar will cut it here not to mention it doesn't need to be immediately aquarium safe as i wont be using this stuff for weeks, months, years, ever who knows.
