Hello, I'm about a month into my first planted tank and I've been having a problem with some green water. I doubt the cause is lack of filtration because I'm running two 20-30 gal HOB filters (no carbon of course) and it's a 20 gal tank. It's heavily planted and there's quite a bit of algae. I dose with flourish and flourish excel along with root tabs. The water makes my tank a bit unappealing. There's at least 100 cyclops on the back wall too. I'm wondering if anyone else has/had the same problem and if there's a cause/fix? Are chemical water-clearers recommended and will they hurt my plants and shrimp? Thanks guys! Any help is appreciated.
