| || | Sponge or Pre filter
I am in the process of setting up my new tank (thanks to everyone for all the help thus far) and have been doing some research on the filtration proccess. I have a two HOB (top fin 40 & Whisper 30) but what I have been reading has been pointing me to a sponge filter of some sort. My tank is 37g and will be filled with zebra danios/glofish, African Dwarf Frog, tetras maybe.
I am willing to buy a sponge filter OR a prefilter. Long term I think I want a canister but it is out of my budget for now. Should I use both HOBs, just the top fin 40, HOB + Prefilter, HOB and sponge, etc?
