drilling bulkheads and set up

[xdragonxb0i]

I never had a drilled tank before so im not sure if this design would work or not. this will be for a 210 gallon with a 55 gallon sump. the pump is a mag 9.5

I will be drilling the bulk head for the outlet. i plan on using 2x 1'' bulkheads. and 1'' pvc pipes.

i never had a drill tank so i don't know how it will work. if i do my design like this, will the water level be where i want it?

also do i need the siphon break? im not 100 percent sure, but i believe it will create a siphon once the water is running through it.


the return lines are purple. I havnt decided how to do the return line. either a spray bar on both sides. Or two pipes running down the tank, to create a a under water current, acting like powerhead.

the only expreience i have with overflow style tanks are with HOB overflow. Any comments and opinions are appreciated

i forgot to add, i would like the setup to be as silent as possible, so if you guys have any other ideas i would like to see them

it will work i don't know about the quiet part i run a MAG 12 & 18 with the return shooting across the surface, it's quite loud

also without the first bottom U from the overflow will work too

Okay thanx guys

When I mean by quiet I just meant water noise is quiet

when i said loud i meant water

thats from breaking the water, okay i think i will run the pvc to the bottom of my tank to make it act like a powerhead

if u r running the return to the bottom u will need to make a siphon break in case of a power failure , by putting a small hole just below the tanks surface water it will prevent over flowing your sump if the power goes out

Silent is a relative term when you are talking overflows...I have 2 x 2" overflows and external plumbing...even at low flow rates external plumbing is going to make noise...the water falling from the highest point to the 1st elbow is where most of it comes from. And it can be heard through 1/4" wall of the PVC pipe.

I have an internal overflow box that is phlumbed through the back wall of the tank. That's what I would change if it was feasible.

If I were you, I would seriously consider internal overflow boxes that run the plumbing through the bottom of the tank. That way the noise will be muffled by the water in the tank and the box itself. Then plumb the rest of the overflow circuit with flexable hose and use long radius curves.

Your returns can also be plumbed through the bottom, inside the overflow boxes, and made to exit at any depth and angle you want...

When I got my tank, I passed on this option, (internal overflow box) and looking back, I really wish now, that I had gone with them. For 70.00 they could have made me 100x more happy, but hindsight is 20/20.

At least look at this option, so you won't end up like me, wishing I could have a "do-over"

when the bulk head is at the bottom, how can u transport it well? do you have to lay it on its other side. so it doesnt damage the bulk heads.

instead of a 90degree drop, how about a 45 degree drop, the overflow will run diagonally to reduce noise

Well...if and when you get the tank, you bring it home a virgin, drill it, bulkhead it, install it, enjoy it, and no need to transport it anyway, with anything installed...I assumed you already had the tank at home waiting to plumb it...my Bad
