Has anyone drilled their megaflow for a closed loop?

Or use the grey pvc type pipe for a little less conspicuousness(sorry I shouldn't try to use big words...don't know what I was thinking)

I was thinking of running mine down to the pre-drilled holes in the overflow, using one as a drain to the sump and one as a drain for the CL. Let me know if you decide to go this route, I'd be interested in seeing some pictures.

That would be cool too. Is there a particular reason why you're going to do it that way? You should do it first and let me know how it goes

And mrbncal, I think it's spelled konspickyousness

What kind of pump is in your sump ??

It's just a little mag 1.9

I've got a 210 and I am thinking about doing the same. Originally I had planned to drill the hold in one of the side of the overflow to make it less visibile. After loooking at it for awhile, I just don't think that it is going to be possible to drill the sides of the overflow. I/you would probably have to drill the hole in the middle and have the intake pointing towards the front of the tank. IMHO it's still better/easier than drilling it.

Did anyone end up drilling their overflow? I was thinking about running returns for a closed loop over the top and down into my megaflows and drilling the front. Here is a picture of someone drilling the side.

Any feedback on drilling the megaflows for a bulkhead?

Well, I just got a new 120 gal so I'm looking at this option again. I'll post pics if this is how I decide to do it. My current tank has the over-the-top style.

Are you thinking of drilling the overflow itself (black part) vs. the back glass? If so, how are you going to seal the internal weir plate (the overflow has a slotted outer weir and an inner solid weir). The inner weir is what keeps the tank from draining past the top of the overflow when the Durso pipe is removed.

I guess you could drill a large hole in the outer weir and then a smaller hole for the bulkhead in the inner one. That would work, but you'd have a gap around the closed-loop intake that would allow small stuff to up and into the overflow. Then again, there's always silicone .

I'll be drilling the overflow itself, then using a uniseal instead of an actual bulkhead. The uniseal should form itself to the irregular shape of the overflow. I hope.

I'd be tempted to silicone around the uniseal inside and outside just to be sure.
