All right ASM recirc. guru’s…I did the recirculation mod this weekend to my G-3 but it isn’t skimming at all. I drilled 2 holes (one for the recirculation pump and one for the feed pump) as prescribed. The feed enters the skimmer body about 3-4†from the top of the cylinder. The feed enters via a ½†vinyl hose attached to a ½†PVC elbow. The water enters the skimmer via a ¾†Uniseal fitted to a ½†PVC elbow that allows me to adjust the direction of the feed water within the skimmer body (basically 2 elbows butted together). I have an estimated 150-200 gph entering the skimmer. The bubbles are about ½ way up the collection cup (experimented with the bubble level as well). I have experimented with greater/lesser flow as well as adjusting the direction of the feed line within the skimmer.
My problem is that I’m not collecting any foam whatsoever. I have experimented with different flow rates and adjusting the direction of the feedline entering the skimmer but to no avail. Also, there doesn’t appear to be much turbulence with the skimmer although it varies depending on the direction of the feed line. The bubble size and water level stays consistent as well. I don’t really understand it. The modifications I made looks almost identical to the other ones on this site as well at ASMskimmer.com.
Anyone have any ideas or suggestions? If not…I’ll probably just plug the holes one way or another and go back to normal operation.
God bless,
