H2overglow Stealthbox set up

[Mbuloverxxt]

Okay guys so I have my overflow chosen and ordered for my tank. It's the dual 1200gph h2overflow with stealthbox. Now I'm trying to figure out how I should set up the inside of the box. I'll attach a picture of what they say is best for 2400gph or more. Which would be the 2 center pipes being main drains with valves at full siphon and 2 back up emergency drains. My only question is. Will this have any noise issues? I know I've seen how people do durso etc but I'm trying to find best applicable option to achieve the 2400gph drain to my the 75 gallon sump.

I found these set ups also I guess.

You want a backup for sure. Generally you have 1 at full flow, and then 1 at a trickle that handles slight changes in flow rate (that is not enough flow relative to the pipe to make gurgling noises), and then 1 that is completely dry as an emergency. But stuff does plug, if you get some big leaves or shells or piece of wood or something you can plug and then make a mess if you don't have a backup.

Aside from that its just personal preference. My recommendation would be to not glue it (inside the box doesn't need glue, a little leak won't matter), so you can easily play around with using the U piece or not, and see what works better for your set up.

Awesome! That's exactly what I needed to hear. Wasnt sure how to go about it

Syphons are really quiet, durso not so much not bad but a little gurgle noise. Just like how the top pic of the video is set up is how I'd do it two syphon 1 either durso or "open lane" ie slight trickle and a emergency drain. In the event of a clog to either of the syphons the open lane or durso would get increased flow possibly making more noise to help warn you of a possible issue. Should that get overwhelmed because of a complete syphon blockage the emergency drain would kick in and if set up correctly should cause increased noise level from the splashing water. Looking at the pics my guess is those are 1" pipes inside the overflow under normal operation a 1" pipe can handle about 600gph, under pressure much more. This is where the syphon comes in. A 1" under syphon can do around 1200gph easily. Hope that helps a bit more.

A question for you. Are you getting 1 or 2 of those units?
If 1, I'd not try for a full tilt 2400gph out of your return pump. I'd go a little lower once all head height concerns were calculated in. Say somewhere around 1800 to 2000gph.
This is where the adjustable DC pumps come in handy.

Of the ones you posted, I'd go with first picture you have. As I mentioned in your previous thread, I prefer the straight pipes over the durso too.

If your sump is able to take ALL the water from the overflow box, you may want to consider replacing the two main siphon PVC with strainers. Less chances of anything blocking it.

Here's an example from BRS.

Bulkhead Overflow Strainers

Absolutely. Helps even more! And actually they are 1.5" pvc. And I think that's what I'll try at first. The 2 mainsiphon, the far right being a durso, and the far left being a emergency. As for how many, I am only going with one of the units. And 2, 3/4" siphon stopper returns. I was advised to use a seperate pump per return. But debated if I should use one, and plumb them together with one DC pump.

The picture is the siphone stopper return.

I agree for slightly different reason. For my set up, the test I did with straight pipe/strainer vs the durso were both dead silent AND turnover was the same. What I like about the straight standpipe is it's simpler, i see how much water is trickling. Also takes up less box space if that's an issue.

Coming out of the box they are 1.5? Wow then you'll be fine as 1.5" not under syphon can handle near to 1200gph. From the little I have seen and read that you've posted to my understanding it is two 1.5" holes supply the box and four 1" go to the sump. If I am wrong then it's great news for you! If I'm right it's still good news for you! Either way a win...lol.
To me 1 pump or two pumps doesn't matter but if you have 1 and it dies then you get 0 flow with 2 you'll get half flow at least something.
I would not waste money on the syphon stopper. I strategically placed hole in the return pipe will take care of any back syphon when the pump is shut off.
