Sump/Refugium/Tank Idea

[manny]

If I were to add a durso stand pipe, I'd have to drill a hole in the bottom of my tank and a hole in my stand? Would I need one or two?

[manny]

Just fyi. The pic with the tank and overflow isn't my tank. I might of confused some people. It's another guys I was hopin to copy but now I'm completely confused and not really sure what to do with my 30 gallon :? :?

By the way. I went to Alamo Aquatics and bought a brand new Oceanic 30 gallon tank today. I'm gonna start drilling it and everything once I come up with a final plan.

Scratch that first idea about the overflow and returns. Here's what I've come up with now. Got most of it from here. Will it work and fit? It uses a 1 " bulkhead drilled in the bottom of the tank with a 1 1/4 " durso standpipe. I still like the sump setup and everything plus what you guys have recommended. I'm just debating about the return (Where to drill a hole for it so it doesn't siphon back into my sump but also get some flow in areas I need it). Do I drill it way up at the top? Another question, can I have a single return and then a closed loop with two outputs running off a scwd?

Anybody have any diagrams of their drilled tanks? Might be a little easier.

Manny if you need ideas come on over. or anyone that wants to see a tank thats in its first months of life and not yet complete come on over, I could use some more ideas.

Manny, you should not need to cap the overflow as there should be no water in the overflow box until you are ready to use it. It will also get "stale" in there. If the anti-siphon holes do not work, that configuration does not allow enough reserve to keep from flooding. (You don't need an anti-siphon hole on the "off" side of a SCWD because there is always positive pressure in the line.) I don't depend on those siphon holes b/c they don't always work. Sometimes they just suck a stream of air bubbles back into the water as the tank rapidly siphons out, and when you need them the most, a snail will be over it. Remember Murphy's Law?

[manny]

HAHA, Murphy's Law...I've never thought of the snail thing happening before Larry. With my luck and living in an apartment that would probly end up happening. When you mention not having enough reserve are you talking about the new configuration with the durso or the old one? And about the stale water, Josh had mentioned that earlier so I think I'm just gonna get everything drilled. Get my plumbing and everything done and have my sump ready and do it all at the same time instead of seperately.
As for that offer Henry, I'm gonna take you up on it. I'll probly go check out your setup when I get back sometime after the 1st if thats ok

Manny, no I meant if you do back siphon during a power failure or maint procedure, with the little end where the return pump sits there is not enough space for an inch of water to drain into it from the main tank. It really depends on the walls of the sump and how much volume there is from normal to the top rim of the sump tank. Looks really close to me.

[Henry]

Manny just let me know. Also just as Larry said, make sure you have enough space in reserve for the excess water when your pumps are off.
