Drain pipe Ideas....

[nanoreefer22]

Well since my new sump/fuge is going to be almost completely filled I'm starting to play around with ideas to stop bubbles from gushing out of the drain pipe, resulting in tons or salt creep.

I came up with three ideas to get air out of the PVC before the water exits the pipe, but I'm not sure if they would even work. Basically I'm going to use vinyl tubing as air vents before the water exits the pipe.

The air will rise up out of the tubes and the water will continue flowing down into the sump.

Would it be a problem if this was submerged?? I can easily make it so it sits on the tank rim and only the water exit is slightly submerged.

It seems like it would work but I might be over looking something.

why the air vents?

So no bubbles enter the sump, then bubbles up and burst on the surface, which creates salt creep and it sounds annoying too.

I've tried a million of these in an attempt to feed my skimmer as much raw water as possible without adding air in the form of large bubbles. These are on the right track but won't accomplish won't you're looking to do. If you make the holes MUCH larger and position them differently you will accomplish what you're looking to do but it will be LOUD! REALLY REALLY LOUD!

You've got a few options:

1. 2 drains and one return - One of the drains is actually just a backup. You place a ball valve on your main drain and throttle it back until it's perfect.

2. Bring your drain into your sump and have the water exit like on a ER or ASM (I have a foam sleeve if you need)

3. Filter sock

4. Really LOUD use of a few "T"s

plus another one or two that I forgot as I try to type and feed my son simultaneously.

I did something like this, sorta like fritz idea, but with 1 drain

Use the gate valve so adjust it so the amount of water is just right. It will be big enough so no particles get stuck and clog it. That will cause the water to flow through, and the air pops from that T in place. If by any chance it does clog, water will start rising in that T and slowly overflow into the sump. It should be a gradual process if it gets clogged. Depending on how fast your overflow is going, would determine how much to turn the gate valve.
... If anything goes wrong, dont blame me. This setup worked for me though

And excuse my crude drawing, I'm no artist

Thanks Ming. Do you think this would work with a ball valve instead.

According to the RC calculator for headloss for my mag 5 I got this "Total losses are 4.57 feet of head pressure, or 1.98 PSI. with a flow rate of 273 GPH. "

So thats very little being drained back to the sump thru a 1 inch drain. I'm starting to wonder if it's going to be as bad as I think it might be.

Fred you think it's going to make noise with so little flow? I know you had/have? yours low flow.

A ball valve would work, just harder to adjust perfectly. ball valves are usually hard to turn a only millimeter, it ends up being turned an inch too much, and then you have to turn it back.
