CPR HOB overflow

[mikeyfromsd]

I figured with my luck, trying to drill the tank would probably end up with me being covered in glass, so I did a little sleuthing on the internet and came across CPR's contiuous siphon overflows. Anyone have experience with these before?

Yeah, they are not the best design. The c-shape overflow doesn't clear bubbles very well so you are relying solely on the aqualifter to clear them for you. If you go with a U-tube style design, they tend to be self clearing if you run a high enough water flow through them. That's what I would recommend, a U-tube style.

Who makes a u-tube style?

[FishBulb]

There are several. Lifereef makes a very nice one and i've heard some good things about hurricanefilters.com. Check out those sites and ask questions if you have them.

I always had some type of flow problem w HOB... bubbles accumulate and displace space that should flow water... Just my opinion.

[FishBulb]

definitely agree with Larry. If you can drill, DO IT. I was just helping you decide between the common overflow types. I just had a small 2 gallons flood last month. Original estimates for damage to the downstairs apartment was $700. I negotiated with the complex to just pay for $350. Soooo, yes if you can drill your tank. Especially if you rent.

Post on the wanted forum, there are usually people with good overflows for sale (Unless you need it to be new). Thats how i got mine.

I have a lifereef overflow. Never had a flood. if you put the return nozzle pointed towards the top it wont overflow if you have power outtage because the siphon breaks when the water level reaches it
