Built in external overflow

[EmilyB]

My new 67g from IA - funky little overflow built in to allow more room in tank.

OK, I have lost count how many tanks do you have now. :question:

[EmilyB]

Actually only 3 now. I'm semi retired. :mrgreen:

I like it :cool: Did they cut slots in the back of the tank,or a bulk head going into the overlow box?

[EmilyB]

Jim, the glass is cut in a curve with eggcrate on there. When I picked it up, the guy there and I both thought it was cut too low. But with the Mak4 I hooked up on it, it is just perfect. I'll put in some black plastic or something so you can't see it so much from the front.

Yeah, I only have three too, but with only a total of 100 gallons. :razz:

What's the little probey thing?

What's the little probey thing?

Grounding probe I suspect

[EmilyB]

Yes, it's a ground probe. Trevor suggested I move it into the overflow - it was in the front...saved me a few times.. :lol: :eek:

[reefhawk]

have you thought about putting an elbow over that outflow pipe? makes everything much quieter. My 180 is from ia as well and has a similar overflow which works really well

[EmilyB]

The overflow is in the back room so I don't really care about the noise so much.

Hi Deb,

Can you tell me if the slots for the overflow box are cut into the long side or the short side of the tank? Also, do you know about how big the box is roughly? Thanks.

(sorry to revive the old thread)

[EmilyB]

Newguy,

In my case they are on a long side. There is a curve cut in the glass, the widest part of which is "three eggrate holes" deep. The box itself is roughly 7" square.

[mr_alberta]

Curved cut as in a smiley face type curve? Also, does it go all the way to the top of the glass?

Thanks!

[EmilyB]

Yes smiley face :biggrin: Right to the top, then framed over and eurobracing over it.

[mr_alberta]

Ahh I see....ok, last question, I promise:

What kind of flow can you push through that slot?

Thanks for all your help Deb :biggrin:

[mr_alberta]

Ah yes, but how far up is the Mak 4 pumping? :mrgreen:

[EmilyB]

Well the Mak 4 is on the floor and split into two returns. So five feet maybe?

I'd make a bigger box for sure with a bigger tank or flow.
