My crappy waterfall filters from walmart aren't kickin it anymore for my 90gal tank. Anyone have alternate cheap suggestions. I love a Do it yourself job!
HYdro5 air driven sponge filters....most bang for your buck thats available in the hobby.
There are a LOT of 'waterfall' type filters in the hobby...some are poor preformers but a few do outstanding jobs....The manufacturer and model would help us recomend an upgrade/replacement a lot easier.
