Closed Loop pump size?

Rate this Entry
I've got a SCWD new in the box that's been sitting around for a few years. I've always been afraid to use it since i had hair algae problems and was afraid it would clog up continually. Well, the Algae problems are a thing of the past, so I'm dusting it off. My Tank is a 50 long, mixed reef.

Any idea what pump rating I should go with? I'm thinking around 1,000 gph.

Anyone have any experience with the Panworld pumps that BRS carries?

Thanks
Phil

    Panworld is a decent pump. If you use 1000gph pump, you'll get 800gph out of the SCWD if used in a closed loop.

    I'm looking at the PanWorld 150PS, which has a zero head flow of 1100 gph, and 1" inlet and outlet.

    Jessy, where did you see those? Or is that tucked away in the stand of your nano?

    im guessing its under her kitchen cabinet.... its an upgrade from the standard "Kitchen Aid" mixer...... lol
    (i have a squid, and it was new and worked good for a week..... all i can say is make sure you put it where you can bang on it with a screwdriver handle or remove it to clean it... (i never had to clean mine because there was never anything in it.... i just had to bang on it every few days. now its just sending water out one port. )
    a friend of mine had a 1" SCWD and he just ended up pulling out the guts and its just an expensice splitter.
    let us know if you got a good one that works good. (id be willing to get a 2nd one if i knew they worked again.)

    Mine's one I bought about 3 or 4 years ago, and no idea how long it'd been sitting on the LFS shelf. It's one of the original 3/4" style. What pump where you using? I've heard they don't work reliably at lower flows.

    I've seen photo's of them opened up and it's just a little turbine with a gear reduction to drive the switching valve. Pretty simple, but I can see it wouldn't take much to gum it up.

    i have a laguna pump (maxflow 2000 i think)
    i have penductors on it, which might screw with the flow and could be causing some problems.....
    your right about the insides just being a plastic turbine.

    The SCWD I've got says it's only rated for up to 1400 gph at not more than 5 psi. If you've got the same one your pump may simply be too much for it.

    That plus the eductors must be really hard on the SCWD. The bigger one allows for a bigger pump, more pressure, easy to connect fittings and an access port to do maintenance.
