Skimmer One

Here's skimmer with about a hr. run time. Blue hose is feed for skimmer pump. Built the "bridge" to raise skimmer and to let plumbing run underneath for main pump.
Skimmer Two

I didn't follow SRK to the "T" on the plans, I made all the plumbing, inside and out, 1.25". The two tube extensions are made of 2.5" acrylic tube that was the inside chamber of a old sea-clone skimmer that I no longer used. The 2.5" tube I ordered only comes in 6' lengths, so that gave me 2 tubes at 36", I didn't want to shorten them so I used the tube from the sea-clone.
Skimmer Two

Here are bio tubes installed, notice ¼ strips of acrylic that frame bottom of tubes, glued those in place then filled frame ½ way with Weld-On. Just a little something I added for support. You cant see them but tube caps are made of 2" Furnco caps with a 2" acrylic disc on inside for support, then drilled to accommodate PVC fittings and ¼" hose barbs that are used for injectors. The 2" Furnco Caps fit perfectly on the 2 1/2 acrylic tube.
Skimmer Two

Here is another shot of base before installation of baffle. The main thing is to get good seams when gluing, don't want any leaks when assembly is done.
Skimmer Three

Sump & Skimmer, white hose is water from tank, blue hose is to skimmer pump, the 2 PVC fittings just below skimmer return are for main pump back to tank. Installed unions at both sump & skimmer, makes for easier removal and height adjustment for skimmer.
Skimmer Four

Here are the 2 pumps, a "Turbo thruster" 500gal.hr. and a Little Giant 1200 gal.hr. But with the 9' head, Im only getting about 650 gal.hr. Will be upgrading to a larger main pump soon, then the 1200 will be on the skimmer.
Misc tree coral

This is a frag I received from G.A.R.F, actually one of three of this type. Only about ½" tall when I got them, now about 3" tall. Epoxied to a piece of rock and they took off, can't see epoxy due to frag growing over it.
