Why does a piece of foam cost so much $$$?? So I am going by this calculation of the famous Olaf and the size mat I need for the power-head I currently own is quite pricey. Time to double check my math as this doesn't sound right.
Haven't yet decided on just doing a vertical wall of foam or the semi circle mount. The wall seems less intrusive to me. For a tank 48" long and approximately 12" deep and 12" high, the vertical mount seems less obtrusive.
