I am new to the would of relays, and circuit boards. I have a little background in electrical knowledge, and am attempting a project. I am working on building an Auto Top Off for my aquarium. I have a schematic that I drew up which is found at 3reef.com. What I am needing to know is will this circuit work? Also I need to know what how many VDC my relays need to be. Will two 5v DC relays work or do I need 9v DC relays. I get mixed up with the voltage information. Any help would be appreciated.
thanks in advance,
Zman
