By J.R. (Bob) Baker With thanks to Lucky for the orignal idea  Start with a few Sun Tea jars (1 gallon)  Remove the pour spouts  For each Bunk, You will need a cap, a Tee, and 2 pices of 1/2" CPVC pipe 2.5" long 
 Assemble as shown. the 1/2" CPVC pipe fits in the bushing w/o silicone. The Cap is needed to keep my bettas from entering the pipe, but don't forget to drill a few small holes in the cap to let water in & out.  When you have one ready, assemble groups of 3.  At the end you will need a valve and a barb 1/2" tubing fitting  Keep adding bunks untill your shelves are full. I got 21 on this 6' shelf unit. I run the 1/2" tubing to my drain but you can use a flower bed Open the valve and all 21 jars drain down to 2" and stop. Then hook up the tubing to a small submersable pump in my aged water barrel And fill all 21 jars with new water in a few minutes. As my father-in-law (Robert French) would say "Sometimes I'm so smart I scare myself !" |
