I am building a water level controller for a 1 and a 2 gallon fish tank. I am using 2 float switches for it, and I have 2 pumps. I want to control the water level of the 2 gallon tank. When the tank level is high, a pump will come on and pump some water into the 1 gallon tank. When the tank level of the 2 gallon is low, a pump will come on and pump water back in from the 1 gallon tank. I want to tie those 2 into a switch, where I also have a continously running mode between the high and the low.

If anybody has any suggestions or schematic ideas, I would appreciate it.

Thanks

 

i suggest you perhaps try using a microcontroller to let you control the delays and stuff with the floatswitches on inputs and some relays to control the pumps on the outputs...

 

Use a latching relay setup.

Sounds interesting.
Unless I'm missing something, why cant you mount the two tanks at elevations where the water level in both tanks is the same and then join the two tanks with a pipe.??

It is the simplest idea I think Eric
