Recently my coralife skimmer pump took a crap. I am not that upset since i have not been that satisfied with its performance from the get go. I started by purchasing two duel outlet air pumps from walmart, four wooden air stones from lfs
, and a small 110 gph
fountain pump that we had. I removed the old feed pump, drilled four small holes in the reaction chamber below the fastener ring, and fed some air hose threw into the chamber.I attached the air stones (four total) and pushed them down in the center tube. Then i cut the air hose where they pass through the tube, attached the check valves, hooked up the air pumps and the foutain pump to feed the skimmer, and started it up. I had to adjust the outflow way down to keep the water level high enough in the reaction chamber. I am very pleased at how this mod performs and the bonus of running the skimmer with less than 25 watts. I have posted some pics.
