I'm setting up a fish room with a few 125s ,75s,55s. I have a handful of sponge filters I plan on using for atleast at first. I was wondering if this would work for seeding them and trying to establish my beneficial bacteria. I was going to take a fx6, or another canister filter off of a good tank that's been running for a few years and clean it like I usually do. Excepted if rinse out the canister sponges squeezing them in one of the new tanks. I'd have the filter water left over in a 5g bucket after. I was thinking I could take a sponge filter or two and put them in the bucket and let them run untill that water cleared up. The sponge would then have all that nice B.B. Could I pop that sponge filter in a tank and be confident the tank has a good jumpstart on its cycling process? Good idea or bad idea?
