MP40's installed :) x 2

i think youll find the mp40's are a perfect fit , on my cube i went with one 40 and one 10 i run the 10 on 100% and the 40 on 70% ,this is with a large substrate sandbed and a mixed reef , i imagine your going sps? if i had my time back i would have went with two 40's the 10 gets hot and is loud running on full.

the 10's dont have spacers, just the rubber spacer;)


cheers

mixed reef this time steering clear of acros other than some stags.

Durso suggestions for a silent life?

running two drains 1" tried the normal T piece with elbow down and hole in a end cap for air intake, but they are sooooo loud and the amount of air getting down to the sump is turning it into a jacuzzi.

The 8' drop has a lot to do with it.

So one for the experts here ;)

why wouldn't ya...after all vortechs rock!!!

I found that the 1" durso was way to loud so I went with 1 1/2" and made all the difference in the world.


Stay clear..... this Bear bites off limbs!!

herbie will work. can't beat the silence of a siphon...

I guess I need to put a balancing valve in? If so can this go near the sump or has to go up by the tank?

I always put the gate valve at the pipe's end before it enters the sump chamber. it needs to control the sihpon properly and because the water throughout the pipe is pulling downwards I think it has to be at the sump.

Ok so what I have learned is this

drain 1 Durso style with balancing gate valve at sump?
drain 2 = open acts as overflow

You balance drain 1 until it stops sucking in air and drain 2 takes the excess water?
