hey everybody, I have a penguin 100 bio-wheel power filter. It says it filters 100 gph for up to a 20 gallon aquarium. I use it on my 10 gallon aquarium that I set up about 4 days ago. It has no fish, but I added some bacteria from a bottle by Cycle. I have a piece of drift wood and some java ferns, but I don't know how long I should run it daily so I don't disturb anything in the tank. Any suggestions?
