Hi,

In a general sense besides aesthetics is there really a difference between between the RR tank and a overflow that hangs on the back such as the lifereef? Pro's con's anyone. Any comments or thought's are welcome.

In a practical sense to me anyways it seem the H/O would be ideal. If you ever wanted to upgrade just move it to the next tank. And possibly it would be easier to get rid of the other tank without a permanent overflow.

RR Tank for sure the better way to go....no syphon break to worry about and fear of mishaps......I have HOB cause my tank is not drilled....tempered glass so it can not be drilled...when time for me to go with bigger tank it will be fore sure RR ready...

Not to be argumentative here but can't mishaps go either way here as far as flooding the overflow? I presume that what you're referring to. Siphon break in the overflow tube hmmm interesting point. Do you or anybody else have any more thoughts on this.

well, if my syphon breaks for what ever reason....the pump in my sump will keep running...and overflow my display tank....Could be my bad though cause my sump holds more water than the level that I keep my display at...however on a power failure my sump will handle any water comming back to the sump....now if my power is restored, and my syphon remains broken then the return pump will put more water back to the display which will cause another overflow..

You make valid points I appreciate it.

However you mention that a H/O has maybe a stronger chance of losing siphon for whatever reason algae,snail ect. Well, if you really think about a RR has somewhat of the same problem. >Explanation< If some foreign matter algae,snail ect. gets caught in the 1" overflow pipe it'll restrict the flow and possibly overflow the tank on it's on. Would you agree with this thought?

I think the level would be lower cause the HOB has the highest level at the top of the tank, where drilled tanks is much lower,,,

got to love float valves...

Do you mind clarifying the first part of your previous post? I lost you in the beginning of the response.

So nice you posted it twice lol

hehe, I can't find a way to delete previous posts!

I think it adds character to the post I'd leave it as is.

i have a 55g that i am setting up with a HOB overflow. this is due to the fact that I didn't want to drill the tank and find out if it's tempered or not.

running a HOB will cause an overflow if it runs into a problem with a power outage and doesn't have a continuous u-tube designed into its construction...this is the overflow that i'll be running, i am under the impression that in the even of a power outage, the siphon will stay intact so that when the power comes back on my return pump won't overflow the display. i'll be testing this as soon as i get the sump up and running which will be in the next 2 weeks. you can also google lifereef and look into the their overflows as well.

The eshopps and the lifereef seem to the same design different price tags though. And maybe a few minor details. I do know this there is no way to get intouch with eshopps. There contact info on their website is disabled. Or it was 5 minute's ago.

Here's a question I have what is the difference in the noise level between the RR and H/O overflows? I wonder how much stress is put on the tank with a RR application compared to a H/O

 

[harlequin29]

The systems are very different, RR with durso's can be silent and safer IMO

In design I agree. But in operation they both serve the same purpose. One drains from the top the RR drops it out the bottom. Or did I completely miss the point. You can get both with durso's or something similar. Basically with this thread I'm trying to get a firm grasp on why one better then the other sort of a pro's vs con's thing.

 

[harlequin29]

They are both designed to get water from the display to the sump. A drilled tank (RR) can draw water from anywhere in the tank whether it be top/sides/bottom. RR tanks are generally safer as they are not electricity dependent.

Your speaking in terms of the CPR overflows correct?

 

[harlequin29]

Nope, I am referring to drilled tanks that take water through the glass pane via bulkhead. CPR and Lifereef 'OVER' flows take water over the top via siphon.

 

[meow]

Evidently I'm failing to understand what your saying..

You said that a bulkhead overflow is not electricity dependent. I agree with this. But then are you saying that the H/O are? or exactly what are you saying?
