View Full Version : Anyone use a commercial overflow?

A few of my tanks are not

drilled and I'm looking to use a sump on a large 60g tank with thick glass... not interested in

risking crack in this guy.

I've seen the ebay hang on the back overflows...

thought they might be decent. I don't quite get how the continious syphon trick works as

I've never had one up close to understand it. Sounds good in principle though.

Anyone bought and tried one of these?

Drilled/not drilled, the problems are the same.

You can't restrict the flow from the tank, starving the sump and allowing it to return too much

water overflowing the tank. Generally the system works best when neither the tank or the sump is

ever completely full. You're constantly battling the possibility of a clogged or crimped hose.

The usual culprits are weak or dead fish or plant pieces. The usual problem areas are the strainers

and tubes on suction hoses and the intake ports to the return pumps. Loose connections, random air

pockets and 90 degree plumbing parts add to the situation. Then there's the rogue hose that

"frees" itself from wherever you have it attached to spray water places you'd never

imagine it could go.

From our member's profiles and TP posts you'll be able to

build a list of possible problem solvers. Some will have photos of their systems either here or on

their websites. Most are proud of their creations and are willing to point out changes they'd

make on their own systems. Of course, we're human, it's easier to criticize someone

else's system.

It's unlikely that you'd be able to buy a system that would

be better than you can create from parts you already have. Of course , if you build it, you

can't really complain... <grin> Dan

Thanks Dan, I suspected as

much. I guess I had hopes that the manufacturer had figured out something better than I've ever

managed in the DIY projects.

If anyone else has 2 cents, please add... in the meantime,

I'm going to go the usual DIY route!
All fingers crossed... one more flood and

word to the wise, use

at least two overflows (more if you are pushing a lot of water).

I have the SOS prefilter box on

my saltwater tank and it runs like a charm.

The only problem I have is it gets plugged

up with algae (I haven't figured out the whole saltie thing yet), and every few days I have to

clean out the "teeth" of the box or my display will overflow.

So if you

don't have plants or anything like that to float into it and block it up, I think they work

great.

Good advice

there! Provides an added measure of safety should one become clogged or lose its prime.

I also agree that, that is good advise. but FWIW I've NEVER had an overflow lose its

prime.

I like the Hang-on-back overflow units. They use up much less space in the

aquariums interior foot print.

thanks for all the tips... I

actually ended up making the PVC self Priming overflows and they really work like a charm. Hard to

justify the money some of the commercial ones cost when PVC cost just over $6
