Well, many people dont know alot about filter's, they just buy them and figure that is it, so there is your awnser to why there arent many replies. Second of all, do you have alot of veiw's? If not, that means many people arent interested in your thread. Third of all, if you wna tsometihn glike a sanister, get Fluval, i dont know to much about them, but from what i've been told, they are the best out there. They are also over a 100 dollat's. You might want to try and get 1 or 2 HOB instead though. I would go with a AquaClear Filter, as they are easy to clean, simply made, so they can be fixed without replcaing anything, just a little know-how. ALso, you can add thing's like Bio-Ball's, which increase the amount of space for beneficial bacteria. Also, you can get thing's like ammonia remover's, carobn bag's, and other stuff. It comes wth a simple sponge, wich traps all the floating particale's, and has room for bacteria. You dont EVER have to replace that sponge as it only needs to be wrung out in fish tnak water, unless it detirorates, and isnt getting the job done. This filters are the best ones you can get for your buck. I own a Bio-Wheel but they get mucked up too easily, adn i have issue's with the wheel moving. I had to throw one away as it wasnt working right after i comepletely cleaned it our with a totth brush, vinger/water mix, rag, special cleaning tool for filter's, and some elbo gease. Nothing worked.
