Excel for my low tech tank
by Pam Phillips
Does seem to help with growth in my tank. I notice perling from time to time. If I recall that's a good sign. Possibly helps with keeping algae tamped down. Easy to use, non-toxic to fish when used as directed.
have a low tech tank, this help the plants without CO2 injection, haven't use it for long, but see new leaf growing ~ fast, will stick with low tech and use this, low maintenance. tfp price is great, will keep coming back, thanks
