i can't do an algae fish because the tank is brackish, and can't do the magnet because of the sand substrate... i clean it with the algae brush on a stick and just don't feel like it does it very well
Lets see a pic of the alge in your tank. green? brown? whats your nitrate level at? is the tank in sunlight? glass tank or acrylic? all of this will help and all ideas so far are good.
