That looks good, I will have to take a closer look. Hopefully I could get something smaller and inconspicious because its going directly in the tank (the bank compartment) and not hidden in a refugium or something.
I have a JBJ nanocube 24 gallon. I clean the filter often, actually one time the problem was I had put a micron filter pad in there and forgot to take it out and it clogged pretty quickly because I had to as the second filter. The second time I was using the surface skimmer and in the middle compartment where you put the boifiltration, I think I had it packed a little tight and it restricted flow, not enough so that I would notice until I came back another day!
Yeah I know what you guys are saying about trying to switch on an iductive load. I am relatively competant with electronics and such but lately I am busy as hell, so this project might take some time. I guess I would have to use a little wall transforer to power power the relay as I would feel much safer with 12 volts going through my tank than 120. Also is there any considerings needed when selecting a relay for AC
current. You wouldn't by any chance be able to recommend any good online sources for cheap electronics, possibility with a part number for the relay you guys use?
