The way the friction and bio load are conected is that the skimmer produces more foam in the presence of increased organics in the water. More foam means more volume for the same mass of water, and as such, more friction in the tubes. Now, i have to say I've never tried using a big non-pressure pump like an ampmaster on my skimmers, just samller ones like magdrive and a few iwaki circulation pumps. What I've found with these is that the water level in the skimmer is very hard to maintain steady. It drops when there is more foam produced, raises when there's less. It's certainly possible that an ampmaster might be strong enough so that this would not ocurr; I was just giving my experience with pmps and my skimmers. For example, my small skimmer works MUCH better with an iwaki 40rlt, rated at 800 gph, than with a mag 18, "rated" at 1800 but probably putting 1200 or so through the injector. This is not just a matter of flow; it's much easier to adjust the skimmer and have it produce a steady foam and water level; the reason for this is that the iwaki is much better at putting out the same flow, even with variances in the back pressure.Originally Posted by kris4647
I can't really comment on what works better with other skimmers, not having the experience with them.
And BTW, I'm certainly not mad for your comments! :grin:
