How long to "seed" a sponge filter?
Does anyone have a best guess regarding how long is "long enough" to get a sponge filter's bacteria firmly established?
I want to get a new sponge filter's bacteria established before breaking an old tank down (old tank has a UG filter), I'm replacing with a larger tank. I'm going to set up the sponge filter in the old tank, add the powerhead and let it run. I'm putting the 40 gallon-rated Hydro-sponge Pro with a powehead in my current 29 gallon, eventually moving the sponge filter to a 40 gallon tank.
I don't want to rush it, but I also want to set up the new, larger tank ASAP!
