Russ, sorry to hear about your algae problem, hope you can get it cleared up. That's the one problem I don't have, maybe the PH (5.5) of the water has something to do with it. Have you tried using bacteria to see if it would help?

Bill, I have 5 PS's in an indoor tank since Nov. and they eat pellets, 2 of them are almost 5 inches so I will put them in the cage when I get other PS's and see if they help train the others.
I'll put a small auto feeder on the wood hatch and put a cover over it to keep the critters out of the food.

Larry
