My new 75 gallon acrylic tank has been cycled for about 3 weeks now. About a week ago I noticed a brown substance starting to form on the sand surface and rocks (see picture). I used RO/DI water and parameters are great and LFS recommended adding a clean-up crew. I am really hesitant on adding too many snails and all that as i don't want to end up with too many after they eat this algae. I also don't want to add crabs as I've heard many people recommend going without them. I purchased 8 snails (a mix of 4 different kinds, no Turbos) for $20 and put them in the tank yesterday. Obviously no difference today. Should I be buying tons more snails? With these small snails I feel like I would need 100! Should I be trying to stir up the sand or use a turkey baster on where it has built up on the rocks?
I don't want to wait until everything is completely brown...
Thanks.
