I haven’t any fish as of yet while the tank is set up to generate the correct amonia levels etc. I have installed the heater, but the temperature doesn’t appaer to be working according to the “tab gauge” stuck on the side of the tank. The heater is hidden behaind the “zen” wall. Does anyone have idea’s as to why it semms to ge ytaking a long time to heat up to 26 degress. Thanks. Duncan
