Hey guys, need a little info on filters and types of filters, as you may know, I currently have a pair of cons in a 10g right now. Im getting ready to buy a 55 or bigger and just wanted to know what type of filtration to look into. (Bored at work and want to do a little researching ) Should I do an HOB or canister? UG filter or not? Just weighing my options, going to buy real soon as my cons are nursing about 50 fry right now.
