Lightbulb Modification to the Durso Standpipe

I finally built one of these for my 55g, and I think I found a way to eliminate the hassle with the air hole-- as far as drilling the right sized hole in the cap and/or using a valve. If someone has already posted my technique, my apologies; I searched but didn't find mention of this.

On my standpipe, the top cap and the short length of PVC (spacer) it sits on (items 8 and 7 respectively from Reefland's website) is not glued. I wedged the spacer pretty tight into the TEE below it, and then twisted the cap around for a while until it was worn enough to rotate with a firm hand. Then, instead of drilling trial-sized holes in the top of the cap, I drilled a 1/8" hole through the side of the cap and the spacer. Rotating the cap lets you adjust the size of the opening. I found that just a very slight turn made a huge difference in how fast the water goes down the pipe. I may try this again with a saw slice instead of a hole to allow even finer adjustment, but for now I'm very happy with how adjustable it was on the first try. And cleaning is a breeze, just lift off the cap and rinse; a Q-tip works great on the hole in the spacer.

Below is a picture of my modification. Now if can only silence the end in the sump.

BTW, my "hats off" to Richard Durso's ingenious device. It has really quieted my overflow.
