Hello everyone.
I am very new to this hobby. Really need some advice from the seniors and experts here. I love I just bought a tank from another member here. It measures 19.5, 17.5 by 19.5 inches. (Including the back compartments) I'm just planning to keep live sand, live rocks, clown fish and maybe anemone in this tank. Not planning to have a sump tank. Planning to do the filteration using the back compartments. However the bad compartments only have a width of 3 inches. Anyone has any suggestions about an efficient filteration system? In each compartments what do I put? Bio balls, filteration balls or sponge etc. As for the return pump, is it possible for me to fit a return pump into a compartment of width 3inch. Do I need a skimmer and if so, any recommendation?
Thank you to everyone in advance
