Skimate Locker DIY:

So I'm on the road 3-4 nights a week and wanted something more reliable than just a 1 gallon jug that can still overflow. So I decided to make an automated Skimate Locker. Skimate goes into the 2.5 gallon container (Sam's Club Animal Crackers). When the level goes up high enough it trips the float valve which signals the Reef Keeper. The Reef Keeper then turns both skimmers off until it is emptied. It also sounds an alarm and sends me an email. Once I add the throat cleaners, it will be a fairly hands off skimmer set up. Pill bottle of charcoal added to avoid stinking up the house as skimate enters the locker and air escapes. Total cost about $10. Had everything except the float valve which was $4.95 shipped on Amazon.

Note: I run 2 skimmers on this tank. For most set ups you would only need one drain line, barb fitting, RO cut off valve and elbow.

1. Parts needed. 1 large container with screw on lid. One float valve. 2x 5/8" hose barbs. 2 90* elbows (TLF). 2 RO valves. 5/8" ID Hose. (With one skimmer only one of each). Rigid airline tubing.

2. Drill holes in cap for float valve and hose barbs. Hole should be a very tight fit so barbs click in place as you slide them in.

3. Add elbows, valves and hose. I heated the hose ends to push over RO valve ends, then cooled quickly in cold water for a tight seal. Other end of RO valve slides into flexible elbow snugly, yet pulls out for emptying the locker.

4. Drill small hole in Pill bottle, cap and lid. Glue in 3/4" piece of rigid airline to lid, and cap. The slide bottom of pill bottle over rigid airline in lid and glue down.

I'm pulling about 2 gallons of skimate a week so this works great for the 3-4 nights a week I am not home. When I put the 450g in this spring I will upgrade to a 5 gallon locker since I will have more space under the stand. I'll add a small pump in the bottom to empty it to the sink drain once a week using RO macro line, or set up a low level float and have it automated to empty when full.
 
Every nice always clean those floats off when you empty. They can get stuck from the bio film in the skimate
 
Nice idea. Are you at all concerned that the float valve is attached to the top of the container and not a few inches down? Basically if you don't empty it and the float valve fails, you've got maybe a couple of hours to do something about it right? If it was further down you'd have a better chance IMO.
 
Over a year and the float has not stuck. It does get cleaned once a when I clean all the system float valves as well as my pumps and wave makers. Most of my floats get calcium scaling quickly, so I keep them clean. Haven;t noticed this one sticking yet, the skimate almost seems to lubricate it, guessing it's the fatty acids removed. Better to be safe than sorry though. A cup of skimate on the floor would stink up the media room for sure.
 
I am maintenance tech an we have in the building I work in a couple hundred of this type of float switch. They will just fail on you when you least expect it. I have a PM that has me replacing critical ones once a year.
