I have a 20g planted tank. I currently have 6 Tetras in there, 1 cherry shrimp, and 1 red crystal shrimp. I plan to add about 6 more Tetras, that's it.
My drop checker is consistently a yellow-green, and I run CO2, I do weekly water changes (about 20%), change the carbon, and rinse everything in my canister filter 1x / month.
I have some black 'filmy' algae that gets on some of the plants, the driftwood, and partially on the bottom. I siphon as much as I can during water changes, but it still comes back.
Would adding more flow help?
I am looking at this pump, and would like to know your thoughts.
