Thanks! I am hopefully starting on this tank in the near future. The one tank I have now with a water feature has the "ungainly" feature of the pump being submerged in the tank. I have to move some things to get to it and it is a pain....I need to change this and may do so soon as I have recently had a tragedy of escaped frogs found dead. Not sure whether I have two or three left and not sure if I have a breeding pair any more. SICK!
