LF : Lifereef overflow box
 

I don't think this overflow box is still in existince in any reef tank anymore, but I am hoping if someone has an old one in your garage/storage could sell it to me. I am looking for 600 to 1200 GPH.

i got a CPR C-Siphon Aquarium Overflow - CS102 Deluxe (1200GPH)
do you interest it? asking for $50 obo

JL just got some good looking utube based overflows in...
They appear to be based on the lifereef design.

Why not DIY?
 

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.

It is so new, I am afraid to use something new without any reviews and flood my floor again :biggrin:

I use a Life Reef overflow. It will be for sale in May/June. Probably too long of a wait, but worth a try.

Eshopps makes good quality inexpensive overflows. The build quality is obviously less than the Life Reef, but they are half of the price (my Life Reef was like $150 shipped to Vancouver). I have used both the Eshopps and Life Reef and honestly the only difference is the thickness of the acrylic.

A quick look at the Aqueon overflows look like they are the same design, but I've never used one before.

I don't recommend any non u-tube overflows. Stay away from the CPR c-siphon.

Edit: just noticed above you have had an experience with the CPR overflow! What a terrible product. JL should stop carrying them.
