my DIY skimmer

I am not quite done, but I could not resist posting a few photos. This beast will be running my 80g reef tank.

Based on the following sites I decided to build my own skimmer. The pump is a Gen-X 4100 needle wheel pump with no mods at this time.

I am gravity feeding the skimmer so the 2 ball valves are to tune the flow through the skimmer. The way I have the output set up I can control the depth of the water in the reaction chamber, and then the output will bypass my refugium. Whatever does not go through the skimmer will go through the refugium.

Here is a diagram.

I'll post progress on the sump as I start work on it.

Thank you to rafael13 for the tank I am using for my sump.

You're going to want the "T" on your outgoing to be just below where you want the top of your water level in the chamber-just below the cone at the top of the chamber, about where the top of the coupling is now.

It looks ready to make lots of foam!
 
wow.. looks great, don't think i've seen one with a non-clear body but my skimmer body gets coralline encrusted anyway so it really doesn't make a difference..
 
Well I ordered a 6 inch clear acrylic tubing, but 6 inches is not always 6 inches. The clear acrylic O.D. was like 1/2 an inch smaller than the PVC so my cone would not work. PVC measures the I.D. and I did not take that into account when I ordered the acrylic. Now I have a 3 foot piece of clear acrylic and a skimmer that will work. I may use the tube for a calcium reactor and/or a phosphate reactor.
 
Rafael,

I have 3 more of those cups just in case I broke a few. One would have worked for your broken one.

You can order acylic pipe in 6.5" O.D.. I got mine in 4.5" so it works with 4" PVC fittings. Interstate Plastics in Sacramento, or mcmaster.com.
 
Looks good.

Almost identical design to the skimmers we (MARS) built last year. Mostly a DAS knockoff.

It looks like the exhaust for the pump is directed toward the bottom of the contact chamber. Is it?

Ours was tangential with a slightly upward direction. This minimized the bubbles in the exhaust.

FYI - I don't see the needle valve for your aspirating venturi intake. I have a bunch of the 1/4 from Aquatic Eco. $10 and it is yours. I can bring it to the meeting this Friday.
