will using a larger ph help produce more bubbles in a skimmer. My skimmer is a "clear for life" skimmer that came with the unit. It works good but I'd like to make it better.
You can also mod them by boring out the intake to get a better flow and/or mesh mod the needlewheel. I've got a link somewhere that shows/explains how to do it if you're interested.
Alot depends on the size of the bubbles produced, diameter of the skimmer body and the diameter of the neck. Assuming the bigger ph will produce more bubbles, it will also push more water into the body. There is a limit on how much air/water the skimmer can handle.
