Megaflow KIts??

[chuckstyl5]

I have a 72 bow rr and the megaflow kit --- I have a mag9 return ... My question is how low does the drain have to be below the overflow??

As much as I turn down the output I still get gurgling ... Also I can feel the air sputter out if the drain vent - do you think I should drill it bigger to let out more air??? Thanks guys

That's tuff to do, What I would recommend is altering your drain with something like the gurgle buster (http://home.everestkc.net/jrobertson57268/HGB/) there are others out there but this is the first one that popped in my mind.

this noise is killing me haha --- i have looked at that .. as a beginner would that go in the overflow replacing the megaflow drain??? the problem in the amount of air when the water hits the sump the air bubble gurgle it so annoying

isnt the megaflow kit basically a durso drain??

A mag 9.5 is too much flow for a standard megaflo kit. They are rated at ~600 GPH, you either need to dial back the pump a lot or get a smaller pump (mag 7 or eheim 1260). The drain only needs to be like 2" bellow the surface of the overflow, and that is mainly to limit any algae from growing in/on the overflow.

For an ultra quiet drain system, you should check out this link

It would work perfectly for your system and wouldn't require a new pump. The siphon drain will easily handle the proposed flow.

Im going to try the gurgle buster first and then if that fails i will go with the herbie - i have about 5 more weeks of cycling so i have time to play with all the plumbing ... i hope something with works .... quick question the larger the air hole in the top the more air it sucks in or pushes out??
