HOB Overflow Dependable Good Flow?
I'm not proud of owning a HOB overflow but I am proud that it gets my water to a EuroReef Skimmer. The HOB I am currently using is a Tom's Aquatic lifter. Does anyone know of a real dependable HOB unit that I need not worry about incase of a power outage? Let me clarify that I have never been worried about my sump overflowing rather that my return pumps water in faster then my overflow can get it to the sump.
Tank Specks- 135 Gallon reef with 50 Gallon Tru Vue Sump

As long as you have the aqua lifter pump for remove bubbles, you're be just fine with that overflow.

I would recommend the CPR overflows. My friend have one since 2003 and works great in his opinion.

I wouldn't.... CPR overflows are notorious for breaking siphon and flooding.
You're better off using a u-tube type overflow or build one yourself. |

I've tried 2 different U-tubes over the years, and the one that's been rock solid is Americle. My spelling may be off, but it's been a bunch of years now. I had bought a non-name brand from Premium aquatics as my lfs didn't have any more Americles in stock, and I couldn't wait. What a mistake!

FWIW you can build one out of PVC pipes and elbows for less than $10 that will be more reliable and work better than the CPR AND you won't even need an Aqualifter pump to make it work properly.

dhnguyen,
Can you go into detail as to how to build my own HOB overflow?

I ran a CPR overflow for over a year, and it scared me. The aqualifters would quit working every 6 months like clockwork, and I always kept a spare pump around. Whenever the overflow started gurgling, I would check the aqualifter, and in some cases, it was PUMPING BACKWARDS!.
It made me very nervous and I will only go with built in overflows from now on. Stu

im sorry but that DIY overflow with all the pvc is horrible to look at, unless you are Sanford and son. if you dont want to drill your tank, the CPR overflow works fine with the aqua lifter. i used one for years. but now i do nothing have RR tanks. and if you dont want to use a aqualifter yu can simply use a powerhead although it will spit air in your tank no and then. the real solution is drilling the tank, anything else is just a band aid.

Not everyone is comfortable with drilling a tank nor want to spend the money to have a glass shop do it. It is obvious also that you don't know anything about HOB overflows as you cannot simply just use a powerhead to replace an Aqualifter pump in the CPR as that would be a disaster in the making. The CPR overflow is by far THE worse HOB overflow out there due to its design. The u-tube overflow is much better and more reliable. Properly setup, a HOB overflow will work without any issues. |

"The CPR overflow is by far THE worse HOB overflow out there due to its design"
Although I said bad things about the CPR HOB overflow due to it "scaring me" It is NOT 100% dependable BUT it actually IS the best design from a flow standpoint. It can flow a lot of water when it is running properly. Stu

I'm surprised no one has mentioned the Rolls Royce of HOB overflows: Lifereef. Same basic design as other u-tubes, but materials and build quality is second to none.
I was fortunate enough to find a used one and it's been rock solid reliable from day one (knock on wood ) |

Agreed with the above statement BUT $90+ is a bit hard to swallow for what amount to nothing more than 2 plastic boxes and a couple u tubes.

Very true, but most people probably wouldn't mind paying a few extra bucks rather than coming home to a flooded room.
I guess my view is if you can track down a used Lifereef go for it. |

I've got two HOBs one from the now defunct DLS Aquatics in Toledo that's 15+ years old and a newer one that's similar.
Keep the U tubes and filter sponges clean and I've never had a problem with the exception of unsupervised teenagers... The u tube needs to be matched to the flow of the return pump and bubbles are continuously washed through and never build up. As far as I'm concerned the biggest downfall with these two is the extra space behind the tanks. That said my newest tank is an AGA 120RR and the overflows take up a lot of room in the tank.... I'm going to glue on some Monti Cap frags to help hide them... Tim

I have had a Pro-Clear HOB overflow running for 3 years now. Not a single problem. I would buy one again if needed.

I have a couple u-tube style that worked well for years. But looking at the boxes now I'd not use these again without replacing them. Seems both are in pretty bad shape from the UV put out by the MH over the years.
The tubes are fine, just the boxes are yellow, cracked and hazed. SteveU

so what is the point in the U on the pvc style i just have about 1in of pipe under water and as long as there is water above it no problems as well as this alows it to stop so that it dont over flow the sump and if it stops and sump return keep running it is sectioned off so that no much water go in the tank so it dont over flow as for pump burning up there is always just enough water in with it to keep it from happening
