Here is the skimmer return assembly. The gate valve allows me to adjust the water level in the skimmer. I also cut the lip off the neck of the bottle so that 1 1/2" PVC would fit. The PVC is also secured for now with silicone.
The skimmer is fed with a small pump I had kicking around. I don't want too much flow through the skimmer so that the bubbles have more time to react with the organic matter.
And here's the skimming unit in a 50G. sump.
I have allowed the silicone to cure, filled my sump partially with saltwater and am now ready to take her out for sea trials. I add some delicious skimmate from my coralife 125 superskimmer to the sump and mix it all around. This is about three days of dry skimmings worth.
This is what I have after 1 hour. It is a dark, dry skimmate.
After a bit I dumped the skimmate back into the sump and adjusted the gate valve to allow for a more wettish skimming flow. This is after 1 hour of wet skimming.
