I have a 30G tank a tetra dual filter with a siphon and internal heater. The problem I am having is the filter runs too high with water when the flow is on high and it spills back into the tank. I have had to raise each filter a hair to let more water through. Also, I have had to turn down the flow to around medium. I took the heater out and am using a single unit elsewhere in the tank as i have had two heaters that went kaputzzzz
Does anyone know of a reason this woudl do this. My water is great but I have lost three fish for no rason other than my thought of not enough oxygen. I have an airstone in the tank as well.
