There is just one drain in the bottom of each overflow. I'll check the levels of the overflows and add a U tube. Boy would that be nice if it works. Denise


A few more options that might help, off the top of my head:

1) Increase the size of the drain lines after they leave the overflow box, at least on the left side. Go from 1" to either 1 1/4" or 1 1/2". This may remove any extra line resistance there is. This solution may go away, however, when you use the full potential of the pump.

2) Increase the size of the drain in the overflow boxes. This depends on how much room there is in the overflow boxes, of course. Do you have a dremmel? ;)

3) Add another drain hole to the overflow boxes. Again, a size restriction to consider.

4) Add another overflow? :(

To use the full potential of your return pump I suspect that an increase in draining capacity will be needed. Do you have extra U-tubes laying around?

The boxes were just a tad bit off, I evened them up and it is working. You guys are great. I am still leary about opening the pump up more, we can play with that Sat. But for now, I am so happy. Denise

Cool, glad you got it working. :D

I'll bring the Mag 18 with me and we can swap them back again, unless your happy with the Mag 12. Your call. The 18, with head pressure should run the 2 overflows fine, maybe close it a tad, depends on your plumbing. See ya Saturday.

Slow, I have a sinus infection with a pretty high fever and am pretty much feeling crappy.

I replumbed the return so the bar sits higher in the back and added more water. It is running almost wide open and is pretty quiet. The water level however is about 1/8 of an inch from the top of the overflow boxes. Is this a problem? I also cut the ends off the return bar and capped it off so the two lock line hoses have more pressure, kind of like a powerhead. I ma going to go back up and lay down, thanks for all your help.

In regards to the height of water, you want water level in the skimmer box (inside of tank) to be lower than the water level in the tank. That way it is skimming the top of the water.

It is about 1/8 of inch higher in the tank than in the overflow. Do I raise the boxes or slow the flow a bit? The water doesn't seem to be falling into the boxes so much, should it be?

I've heard some people say it should drop as much as 2" inside the box. My inside box drops about an inch when everything is clean. If there are things that are slowing down the flow (large bubbles, algae, snails) then it doesn't drop that much. If your inside-box water level is only 1/8" below the tank's then I would say that either the overflows aren't draining fast enough or you need to adjust the heights of your gurgle suppressors in the outside boxes to a lower height. I would start by playing with the latter.

When the airline in the gurgle buster is plugged the water drains faster, I am having a hard time adjusting it any other suggestions?

What type of overflow was it - looked like a lifereef if I recall? Personally, with my lifereef slimline (3") overflow I have had great luck with stockmans.

Well, I tweaked a bit and it is running better, it seems to be keeping up. If I have more problems I may have to try the stockman. Thanks, Denise
