overflow boxes
 

Who is using overflow boxes?
I know they tend to be less than desirable but I may be forced to use one.
Any brands which you can recomend? I have read that the CPR looses siphon.

I have been informed that a few members may actually manufacture an overflow box, this is interesting if true?

Let me know what you think

If you mean siphon overflows, I have been using one since my tank was set up about 3 or 4 years ago. It has never lost siphon. I think the trick is to keep the flow fast enough to prevent bubbles from collecting in the siphon tube.

Yup . . mee too (im using a cpr brand) . . . Mind you Im using a cs50 model (the smallest one about 300gph) . . . Mine came with an aqualifter pump to prevent siphon loss even at power outage . . . Had it running on my tank for about a year and a half . . . :cool: Excellent product for me. JME

RobW what brand are you using?
Megatron, the aqualifter pumps water right?

I am using one I built myself. It is on a 50 gal tank with a velocity t4 return pump.

I can tell you bear27 builds a real nice overflow box. And he builds them to spec - always nice when you can get exactly what you want. Costs were very reasonable IMO - mine actually cost less than a store bought (but I supplied my own acrylic)

Bear will probably want to smack me around for not cleaning it up before posting a picture - but just know the salt creep and grunge is from testing - not construction :)

Albert from Golds was telling me about how bear27 makes them. Looks quite nice.
I will have to contact him to get a quote.
Andy, where did you buy your acrylic?

I have read so many threads saying the CPR overflows where no good, but it seems you guys are having really good luck with them. Im confused, Utubes or weir style?? I guess it comes down to personal opinion.

I really dont like equipment that looks unprofessional. The bear unit is very professional.
Andy do you think black acrylic or clear would be a better choice? I know the black will prevent algae growth but the clear you can always see whats going on.

Bear27 is a member right here - pm him and ask.

I had the first one built out of clear - didn't like how I could see through it - crud will settle into it, looks out of place in the tank - and the grate really stood out (of course that was because I built it out of eggcrate).

Mine's actually built out of "smoke" acrylic - it's not black if you shine a flashlight on it, you can see through it...

My acrylic came from excess / cutoffs from work - you'd have to talk to laird plastics or someone along those lines about costs of acrylic etc.
