    How much Flourish Excel should I be using daily for a 20 gallon tank?

    None! Unless you're using it to spot treat algae

    Excel is glutaraldehyde. It is a biocide. Long term use is harmful to both plants and fish. Do not use!

    The dose on the bottle says 1 cap (5mL) for every 50 gallons, so for a 20 gallon it's 2 mL.
