Hey guys, I had a green water problem and upon recommendation from my aquarium store I bought a UV
filter at $60 from PetsMart (the aquarium store's lowest buy was $130), which was rated at <50 gal
. Ran the filter for ~4 days and my water's crystal clear now. My question is - should I keep it running, or only run it 1-2 days a week, or what? The lower my electrical bill the better, but I also don't want to skimp on getting good filtration in my tank. Thanks!
