Fish Crazy
Hey just a quick question, i have a 100 liter tank (24 galloons i think) and i'm using 2 power filters, 1 aquaceal pumps 375 l/h and 1 dolphin pumps 250 liters p/h, I'm also using a smallish box filter from a cycled 50 L tank. Now i would like to know if i surround the box filter with gravel pretty much all the way up to the top would it still wok. I have set up a cave next to it and would like to disgus it as much as possible. or does these things olny work ontop of stones, not submereged?
