acerkai640;3935459; said:you could squeeze someones filter in there and add some ryobic k37 (lowes $15), i would say the full gallon. i used a half gallon on my 115 and it was cycled overnight. ive used this method on 2 tanks, my buddy used it, my LFS used it too. you could have your tank cycled in 2 days to be safe. just my opinon good luck
make sure the gallon jug smells like rotten eggs if not dont get it find one that does
