Interesting. I had a similar exp with mesh modding an ER RS250. Stock was ~ 18 LPM, mesh was ~ 20 LPM. It used a LOT more power, was much noisier, and I could never get it to skim as well as the stock PW impeller. It seems people have the best success when modifying a pump that is an underperformer to begin with, not a setup that works well.
True..
I am getting great bubbles, though. If the bubbles are better or not than stock is pretty subjective... So I really do not know if the mesh is an advantage or not... Air-wise, it is nice knowing I have that extra power. I have yet to let the skimmer get real gunk filled, so once the neck really gets coated if I let it run for awhile, and the skimmer broken in, it may be a different story.
Unless I get some way to lower the turbulence or get a riser hooked up, the extra power is a novelty. Or maybe the skimmer will start acting different after a couple weeks of use...
At this point, not only does lowering the level not help, but it is also the opposite of what you would want. I would be going well under 100 GPH, which is backwards. In fact I would probably rather get up to 200 GPH with more LPH. AT least this is what I have gathered from my reading...
Here is some pictures of the skimmer in action before I changed the airline and did the 4 layer mesh mod (I had two layers on top of the impeller at this point, no pins cut, pulled the same as stock).
Lol @ break in times. My skimmer has had no time to break in.. I have been messing with it so much with different configurations, I need to just let it run now and see what it can do.
I'll see what it produces today with the final setup. It produced about the same in these pictures overnight.
