LF : Lifereef overflow box

[Reef Pilot]

Foolproof overflow. Will not lose siphon due to micro bubbles, and will auto start even after power outage. Airline tubing is connected to return pump input. And totally quiet.

I was using an undrilled tank as a refugium for a while, and made this out of 1 1/4 inch PVC. Worked great.

Any utube based overflow, IME is foolproof.
Microbubbles should never be an issue if set up properly relative to your flow.

Thats a very interesting design there and one I havent seen before...
Very cool, thanks for sharing, I think I'll try one of those soon.

for 65-70 bucks though, hard to go wrong with the Aqueon at JL.

I still run one.
Can't afford a new build, so re-used ol'cichlid tank as reef.

I had tried CPR before and I got a flood about 5 gallons of water on the floor because the stupid pump stopped running. Thank God, nothing serious damaged. Since then I am using a Lifereef overflow box until now. It is a very reliable one, never failed as they say. I was ordered a 300GPH overflow box from Lifereef, I didn't realize it was way too small for my tank. I need a bigger one, but I don't want to order a new one again because its expensive plus the shipping, it is a little bit over priced for me. I am hoping I can find a used one, because as I can see people today is having a RR tank instead of using an overflow box. When I bought the tank it was not drilled - my stupidity - I have no choice but to use an overflow box for now until I change to a new tank in the future if I need to move again.

The only scenario that I could figure might cause a flood is if the overflow pipe slits become clogged. But you can add a 90 degree elbow to the end of the overflow pipe instead of a cap, and cut the open end to be just a little higher than the overflow pipe with the slits. That then serves as your emergency overflow.

I should also mention that you can handle more flow if you lower the T at the back. I needed it high on mine to drain into my sump. And I used an airline valve in the tubing to regulate the water/air flow to the return pump, or close it if I wanted to for any reason.

I don't know why people fool with these overflow boxes and U tubes. Definitely asking for a flood, sooner or later.... This PVC pipe design is a lot safer, and cheap, too.

Did you copy it from somebody or it was your own design ? When I look at the picture, I am not really 100% sure how it works but it looks like a very talented idea.

No, can't claim it all as my idea (I am not that smart, LOL)... I adapted my design from some others I have seen on the internet.

The key is the airline tubing to connect to the low pressure side of a pump. That removes the biggest risk, which is losing siphon. The idea of using the elbow at the end of the intake overflow tube as a secondary emergency overflow is mine, or at least have not seen that anywhere else.
