Don't forget about head pressure.
They really are only as good as their pump.
The ev400 with a mag 12....1200gph and 15' head probably wouldn't even make skimmate.
I consider my mak4 a middle of the road pump for an ev400..... 1190gph and 22' head. I'd be better served with the genx pcx-55hp.....1140gph and 26' head, or better still, the Pan World 150ps.....1100gph and 28' head. (the one Leopardshark had)
I don't think the mak4 is a true high pressure pump though, running the skimmer it reads 88-89 watts on my kill-a-watt. The other better pumps listed I think (since they're true pressure pumps) would be less forgiving in the electricity department, but those who have seen it, know what more pressure can do when you're already maxed out on flow.
I believe the key to getting the best pump, is to match the proper flow for your model and then get a pump with the ability to handle the most head pressure in that flow range.
The key to swallowing your pride when you realize you could have a better pump (for the second or third time?)......
HI, I have a aqua c 120 and struggled for a year to get skim right,
last week i got mad and threw a mag 9.5 that i had laying around.
It pulled out more in a week than it did in three months. i mean black gook that i couldnt believe. I now love it

:thumbsup: That pump I feel did the best on my ev180 when it was stock. It has a 14' cut off. I had also tried the Ehiem1260and62, both of which can handle less head than the mag9.5. It's good to see it works well for the ev120 users too.
