The main project is to create two closed loops to replace the powerheads that can be controlled by the wave maker function in my Reefkeeper 2. Using elements of http://www.melevsreef.com/closedloop.html (minus the scwd) and http://www.wetwebmedia.com/pbh2oret.htm Wouldn't it be good to create a clockwise water column rotation for a few minutes and then reverse direction to create a counter-clockwise rotation? It could be done with a power head in each corner but I don't want powerheads in the front. Is it hard on the mid-size pumps (~800gph) to turn them off/on frequently?
That is supposed to be tough on the motors. I would get an Oceans Motions Squirt, $150. And then only run one pump. I would take that filter off of your sump pump, more maint and it probably does catch some bugs.
It's called a hot loop and a spray bar. A hot loop is fine the only disadvantages is the visable pvc in the display. A spray bar tends to plug up with algaee or coraline. Unless you have larger openings then you would need to beef up the return pump to make full use of the spray bar. I would nawing a not mess with the return unless you wanted to add an Im drawing a blank its the device that makes the open end of the return piping to swivel. And I would go with a Oceans Motions product, say a 4way or squirt.
Sorry Joe , I have rather large hands trying to type on a lap top. The curser keeps changing lines and messing up what I have allready typed.
I have a Dell with a touch pad and track stick in the middle of the keyboard. That stupid stick caused so many problems for me, and I finally installed the utility and disabled that thing!
