Well I am planning to go to Cancun for 5 days for some diving on 4th of July weekend, and needed some peace of mind for my tank. So I came up with this for under my stand. 1-Rio 600 pump 1-10' Clear hose flexible $4.50 Home Depot 1-5 gallon bucket with lid $6 Home Depot 1- ordinary extension cord $1 Dollar Store 1-liquid level switch P/N 2A554 $13 @ Grainger (DX7 told me of this, I love you man) 1-6" piece of 1 1/4 PVC $1 Home depot 1-1 1/4 end cap $.88 Home depot 1- 2"PVC to 2" thread coupling $1.40 Home Depot 1- 2" stop cap $.88 Home Depot 1-1" PVC to 1" thread coupling $1 Home Depot 1- thumb screw $.60 Home Depot 1- 14"x2" plexiglass Home Depot I cut two holes in the lid of 5 gallon bucket with a hole saw for door knobs to fit the 2" and 1" couplings, and screwed them in as shown. the 2" is for refilling easily with out lid removal. The 1" easily accomodates the flexible hose leading to my sump. I got a cap for the 2" fitting to keep things from falling in. I drilled 4 vent holes in the top of the cap. For the switch I drilled a hole in the center of the 1 1/4 cap that allowed me to thread the switch into it. i then drilled vent holes in this as well. with the switch in place, I slid 6" of 1 1/4 PVC into the cap. I used 6 " to help eliminate near surface wake or waves from cycling the pump. I then spliced the switch leads into one leg of the extension cord. Now I needed a bracket for the switch to be hung with. I cut a 14" long by 2" wide piece of plexiglass, and bent it using a hot air gun (I believe a super hair dryer might work as well) into the shape shown. drilled a hole in one end for the thumb screw, and tie wraped the switch to the other. I added a felt pad to the end of the thumb screw, because I could not find a plastic thumb screw. Instant piece of mind, for approx $30 plus a pump.
