I have a 20 gallon long with a finnex fugeray planted plus. I have a aquatek pressurized co2 system. My substrate is carbisea floramax capped with regular black sand from my LFS. I EI dose with dry ferts. My water column is 9 inches and my led is currently hanging 4 inches above the top of the water column ( it can be lower if needed). Do you guys think I will be able to carpet glosso with that set up? If not what other fast growing carpet would work better?
