I Need Help With Plumbing For A Drilled Tank!!!

[Chef]

Hey people...I was wondering if I can get some expert help from people who have drilled tanks. First of all, I'm working with a 150 gallon tank that will be drilled for a Eheim 2260. Second of all the bulkheads that I have are a larger than the connections for the eheim 2260. Do you normally seal the bulkheads with silicone or some kind of gasket maker? I'm not running any overflow box...so the flow will be directly down from the tank through the eheim then piped back up. I understand this will cause tremendous pressure. The bulkhead fittings are larger than the eheim connections, what do I do to connect the eheim fittings to the larger bulkhead fittings? Will I still be able to plumb in the quick disconnects from the eheim or will I have to lose that feature? Also how do I assure that the pressure coming down won't bust the connections at any point. Chime in people...I'm curious to what the experts have to say

Just use normal bulk heads.

there should be a rubber gasket on it.

I use sealant on the top and bottom of the gasket.

There are threaded and non-threaded fittings to convert the bottom and top of the bulk heads.

You want a strainer for the top part and a 1'' hose barb fitting on the bottom to fit your ehiem hose into.

Examples of what you need. Size will depend on bulkhead.

For the return, you want to use locline connectors and loclines.

Sized according to what you need.

You should be able to run the QD as is.

Hope this helps.

Just make Justin a fried fish platter and have him come over and do it.

I don't see why you need to drill so you can use a canister filter? You are adding failure points into your system.

I do not want to have any lines visible. There can only be failure if the lines aren't secure. Lol then there will be 150gallon of water iny bedroom.

You think? I'm gonna dangle a filet of catfish over at his shop. See if the beast will awaken if he's not pissed

You need a reducer to bring the connection down to a diameter where it can accomodate a Barb X MIP fitting.
I don't remember exactly, but i think the 2260's hose is 5/8" ID.
You are going to need a fitting with a 5/8" barb and an MIP which is the same as your reduced bulkhead connection. But unfortunately that is not carried by HD or Lowes.
Connect the fitting to your reduced BHD connection and connect your hose to the barb and secure with a hose clamp.
Try Fish Gallery, they might have it.
Or you can go here, where i get all my fittings.

But word of warning, you are going to have head losses if you plumb your outlet through a reducer and you flow might be really slow.

b/c drilled tanks look clean compared to ones with hoses and lines everywhere.
