Hey guys. i bought a gentelly used 75 gallon tank including every fish accessorry for $300 bucks. The thing is, The filter the guy sold me was a awesome canister ehiem filter that worth like a hundred bucks (I think). I'v only power fillters my whole life so I barely know anything about. so I have a few questions.
1. Today i cleaned the piping of my canister filter cuz there was a crapload of algae and fish poop stuck on the pipes. When I took the bottom pipe out that was connected to the actual canister, dirty black water was spilling out so i went to my garage sink and pourd it out. i later "filled" the canister with hot water via the canister hole/openning to flush the rest of the filthy gunk out. it took me 10 minutes to do that. The question is what is that black dirty water. fish poop, good or bad bactera, algae etc?????? Was it a good idea to flush all the water out??
2. OK another question is that the previous owner of the filter said i can "instant cycle" the tank if he DIDN'T clean out the filter. The problem is, i've read that once the filter isn't running for a period of time, the good bacteria will die and this deadly bacteria will over take the place and kill the fish. I THINK I've experienced this once so i don't want to encounter this again. But I was wondering if this was true because my new canisterfilter is in my garage and it is not running with the bacteria, dead or alive still in it. is it ok? should I rince it?? I know these are long questions but can some nice people help a canister filter noob out???


thanks!
