Okay, I know what a sponge filter is, but not understanding how it works better than a power filter. How are you controlling the ammonia?? I like that concept but just worried about stagnant water. Do I add bubbler bars or rain bars?
I'm setting up a divided 20gallon long. I'm using plexi glass that I'm drilling holes in, but I'm alternating sides that I'm drilling to create movement (like an s pattern).
Any help would be greatly appreciated. I'm posting a picture of a tank with dividers but it is NOT my tank but my tank will look like this except I used blue plexi glass.
