Ugly skimmer pics.

I was doing a water change and decided to post a pic of my DIY skimmer. It is based on the ones promoted by Randy Stacye's web site and is all pvc.
The body is a 6" riser tube from HD, the pump inlet is 3/4" pvc, the outlet is 1.5" pvc with a gate valve. The pump is a Rio 1700 with a venturi attachment. The collection cup is a plastic quart jar I got at Dollar Tree. I got the uni-seals from bulkreefsupply.com. The extra 3/4" plugs are from when I originally was going to try to do a recirculating skimmer, but there wasn't room in the sump, so it's just a needle wheel with a mesh mod.
The bottom is supposed to be rubber end cap like you would use on a sewer line, but I couldn't find one of those right off hand, so I glued/siliconed a piece of plexi-glass over the bottom. You'll have to excuse the corralline, and if you had a magnifying glass you would see oodles of baby limpets clinging everywhere.

 

If I remember correctly the most expensive parts were the neck which is a 3x2 drain fitting, the union which connects the collection cup and the gate valve. The total was probably between 40 and 50 for parts. I have it on a 75 gallon with 55 gallon sump, total volume probably about 100 gallons.
