I have a 55G AGA system with three HOB filters and macro that just floats around in the tank with the livestock. I am going to add a sump/refugia under the tank this weekend. I bought a submersible Rio 10HF (Hyper Flow) pump for this. I do not have an overflow, and don't have a real understanding of how overflows work. Do I need an overflow?, If so, can I make one myself? How? Thanks in advance! Alex

STOP
Unless you like to have water floods on the floor, do not do anything until you know how to keep it from flooding. ------------- Reefkeeping Tips, & quick, easy setup tricks: www.utahreefs.com/forum/forum_posts.asp?TID=9244 Pay it forward - become a paid WMAS member

This has been discussed here plenty. I suggest a search to read and view diagrams posted previously.
A simple hose/tube over the back of the tank leading to the sump/refugium will siphon water out of the tank and flood the floor unless specific measures and equipment are utilized to prevent it. Also during and after power outages, the overflow system must be designed to allow limited water to drop into the sump during a power outage and for the system to restart without having lost the syphon when the power is restored. In addition to what you find in your search, I have a write up explanation and design of a simple overflow if you would like to email me and request it.

| What about using a check valve to stop siphoning when power goes out? |

I have a overflow box. It came off my 55. I got it on ebay for $40 with shipping. It can handle up to 800gph. That would be turning your tank over 16 times Hr. Thats with 3 u tubes. I used 3 but I was only pumping 600gph. Rio hyperflow 12.
I would sell the overflowbox for $25 Kamaron 808-1591 I never had a problem flooding. |

No good. Don't even try it. It will get clogged and fail. Have you asked for my article? Do you need to discuss? My number is below. ------------- Reefkeeping Tips, & quick, easy setup tricks: www.utahreefs.com/forum/forum_posts.asp?TID=9244 Pay it forward - become a paid WMAS member

| I would look around for an overflow box. It's just easier. than a DIY box. |

I have an overflow box (CPR) and it is rated to flow 1400 gph. I've never put it to the test, but I'm hoping to very soon.
Anyway, I suggest that if anyone has the chance to drill their tank in lieu of using an overflow box they should do it. There is just a much larger chance that the overflow will fail. And it will fail while you're on vacation - that's just when these things happen. Its some type of universal law or something. Mine failed while we were in Yellowstone a year or two ago.

I made a pretty decent, solid, and stable overflow for my current tank with 1.5 inch pipe. Because the tank is in the window and I didn't want to drill the back and because I will eventually move it to a new place, it just seemed better not to drill it at all. But I do agree that drilling a hole in the tank is better. And an uopper back or upper side hole, rather than a bottom hole, is just as efficient and frees a lot of space for LR and coral. ------------- Reefkeeping Tips, & quick, easy setup tricks: www.utahreefs.com/forum/forum_posts.asp?TID=9244 Pay it forward - become a paid WMAS member
