hang on overflow for new build

[AWDcameoLSX]

If it is not set up now just drill it and you will not be sorry you did. Much lower chance of something happening.

Do you have the ability to move the tank safely?

I have used a CPR overflow and the ones that use the "U" shaped tool. I have never had problems but I would
drill. Cleaner look and less up keep. If you don't drill check out the CPR overflows.

yes i can safetly move the tank

Eshopps or lIfereef.. Those 2 I know have the continuous syphon feature that don't require a pump( that WILL fail).. I've been running the Eshopps for years without a single issue as have a frien of mine. He actuall has two of the largest units on a 300 gal.. They never lose syphon and you can tune them to be quiet just like a normal overflow with a herbie. Just use the pump calculator to determine head loss while purchasing your return pumps and you should be golden. I've never seen or ran the litereef but it seems to be the same as the Eshopps ( more $) maybe better built I don't know.. Same concept though..

But if you can drill and add a glass holes box or similar over it that is prob gonna be the cleanest looking option and possibly easier to maintain IMO..

Good luck and don't let people talk you out of hob overflows if thats what your wanting ,choose wisely and dont have to rely on a pump to keep the syphon it's literally the same thing minus a piece of acrylic going over the rim..just my 3 year experience with the Eshopps overflow only not any other I can't comment on those with certainty. Again good luck with the new tank whatever you choose .

Coast to coast with Beananimal is the best, imo.

I don't have the huevos to drill, so I got a Lifereef box, but I also had him make me a custom sump!!

Here is a link to some internal overflow boxes if you drill. If you have the shop drill, have them silicone one of these boxes into place at the same time. Match the flow of the pump to the recommended flow of the box.

I have an Eshopps overflow box and after reading all the bad publicity on this site I was nervous so spent a week testing every possible failure scenario. The only way to get an overflow is if the drain pipes clog to the point that they can not keep up with the return pump. This can happen on drilled or HOB overflows so IMO if you get either an Eshopps or lifereef (avoid HOB that require aqualifter pumps to maintain siphon) you have zero increased risk of flooding. Cant speak to other experiences but this is my opinion.

Otherwise its just personal preference. If you want to maximize in-tank space or avoid drilling get a HOB. If you like the look of an integrated overflow or if the drilled tank makes setup of your sump easier go that route. HTH

I also recommend LifeReef. I never give mine a second thought. It always starts right up after I suspend the return pump for water changes or during a power outage. Jeff at LifeReef will tell you exactly what you need to get started and can provide the return pump, ball valve (important), hoses, nozzles, etc. If you decide use an external overflow, either get the LifeReef or the Eshopps. No others that I'm aware of are as reliable.

alright so come to find out this tank is tempered and cannot be drilled so I went with the Eshopps 200 dual for my overflow and will be running a 20 gallon sump with this setup. thank you all for the advise now I am starting the construction of the new tank. once I get it up and through cycle I will be adding a UV sterilizer to it, an recommendations on those

Eshopps is moderately-priced and works perfectly, as long as you have a proper-sized return pump. If the pump is too strong, any overflow, no matter what the brand, won't keep up and your tank will overflow. If it's too weak, the air bubbles will build up inside the U-tube until the siphon is broken, which will again lead to flooding. You need to have a pump just strong enough to push the air bubbles through the u-tube, but not so strong as to be too much for the over-flow draining capacity.

 

[EllieSuz]

The solution to the problems Bruno mentions is to get a pump slightly too large for the overflow, but install a ball valve on the return side so you can dial it back. These overflows have a "sweet spot" and a valve allows you to experiment for just the right flow.

 

[bsilvest]

Thank you for the advise which exactly what i have done i have a ball valve on the return line where i can reach it easily an on startup will do it this weekend when im ariund to olay with it all day.
