The only filter I have running right now is a regular HOB with regular cleaning sponges as the filter media. They are large square sponges I bought from the dollar store.
Actually, this is exactly what they are, except I cut off the green scrubbing part.
If a second DIY filter(with the little scrubbies) would be beneficial, I'll do that immediately after my blackout.
and no nooo you're not being a pain. Lol, I'm asking to many questions.
Speaking of questions, I have another about changing the filter media.
In the HOB I have two of those regular cleaning sponges. When I clean the filter I should only replace one at a time to prevent the depletion of beneficial bacteria, right?
