I got it second hand last month and wondering if the pump is good enough for now?

Is it an 8" x 30" skimmer? If so, an SP3 (Sedra 5000) is way too small a pump. I can see why ER got such a bad rap in the past. They now use that same pump on much smaller skimmers. The current skimmer that would be most similar is an RS250 which uses an SP5 which probably draws 3x the air of that SP3.

So, its a 30" x 8" recirc? If so, the ER SPE5 (Eheim 1262) would be the one to get.

Thats a shame. A new RC250 is ~ $1000. It would have been cheaper just to get a new skimmer. Not sure what to recommend at this point.

thanks for all your input sjm817... anyways is spe5 upgrade thats $310.00 the one i need cause they have a 3 different kinds with different pricing...and do u know if the upgrade is just plug and play with the union already mounted on the pump?

Not sure on which one is right for your skimmer. I'd give ER a call and see what they have to say.

Almost forgot!

If your thinking of changing pumps anyway.......

I'd do the mesh impeller mod to the 5000 first and see how it works. Then spend the money to add a second pump or 1 larger pump. ( I'd probably go with a second pump ).

I've done the impeller mod to my ASM G4 and a buddies older 8-2 ( and converted to a recirc ) and the added performance is pretty significant. Certainly would try that before spending any significant money on changing pumps.

Yeah, that's another option. The current Eheim pumped RC250 draws ~ 15 LPM. Dont know if you could get a single Sedra 5k to do that with mesh, but I would think 2 would be no problem. ER used to have the "+" model of that skimmer with 2 pumps.

will this work? if i upgrade to 1262 for my 8-3 and add the spe3 that was in the ER to my asm g3 as a recirculating, is it posible to have one normal and one recirculating on the G3?

If you do upgrade to the eheim, make sure you ask them for a pump sized to fit your skimmer's holes. They changed hole locations when they started selling the eheims, so they have to make special "upgrade" eheims for owners with the older bodies.

As far as the mesh, give it a try. I'd invest in an air meter too, if you don't already have one.

It might save you $300 beans ya know :)
