Overflow box and flow rate

[Luis Figueroa]

My only option I have is the purchase one of these bad boys for my non drilled 30 cube. I have a mag 9.5 but at 4 ft it's power is reduced to only 700 gph! I've heard that air bubbles trapped in these are caused by lack of water flow, and that's not even taken in to consideration I want to add a manifold. So my question is should I buy an over flow rated under my return pump?

700 gph is too much for a 30 gallon tank in my opinion so you could add a manifold to that pump and be fine.

As far as the Overflow you certainly want about a

The lifter pump helps with the restart.

BTW, I have about 400-600 gph flow, depending upon settings, on my 100 gallon and it works well.

Ok. I just didn't want to have less power or flow in my dt for the overflow to work properly. I'm looking a getting the lifereef overflow box since the lifter pump can fail and I don't want to rely on something that can fail.

My brother uses the Eshopps, but there are others. I agree on the pump failing, but I figured it was an extra help on those, but maybe not.

I rent and it's on carpet so I can't afford a flood and my landlord would be pretty ticked if it happened hahah

I have an eshopps but plan on drilling this spring. They're kind of a hassle. But they work.

Besides noise what issues do you dislike about your overflow box

 

[Lowstorm]

Actually there's very little noise after they are broke in. My only complaint is that since I don't have enough flow to run both tubes it's operating on one. If I got a stronger pump both would work fine I'm sure. And starting it is a pain. I rigged mine up with a aqua lifter for a just in case scenario.

Eshopps are said to have an automatic start up in case of a power outage. Since your return pump doesn't have enough flow you use a liter pump to keep siphon is that correct?

 

[Lowstorm]

They do start up most of the time. But all it takes is one large bubble to break it. So yup it's just insurance.

Noise can be fixed in an overflow box. 2 U-tubes should eliminate the bubble issue. No pump. It starts automatically when power comes back on with the eshopps

I have an Eshopps on my 75g for almost a year and a half with no problems at all. The first thing I did was make a silencer for the noise, but besides that no other modifications needed. I do a weekly wc and the siphon starts as soon as I start the return pump. The only complaint I have is that the U-tube gets a lot of algae, but at just $8 I just by a new one and replace it, which is 3 times a year.
