Glass-holes recommendation please

[cnreef]

Hello,
I'm planning on drilling a 29g tank soon with a glass-holes kit. I want to eventually upgrade to a 75g tank in a year or so. Therefore, I am curious if I should just buy the 700gph overflow for the 29g or could I buy the 1500gph overflow and then be able to reuse it for the future 75g upgrade? The 1500 gph overflow's recommended continuous flow rate is 500-1000gph so I figure I could go on the lower end for the 29g and then the higher end when I use it in the 75g.

Thanks for the help!

I use the smaller one on my 85, I didn't want much more than 500 GPH through my sump anyway.

Hmm yeah true, I prefer lower anyways so I think I'll use the 700 for both my 29 and eventually the 75

Another option might be to go to flee bay and use "Bulkhead Mount Overflow Box CPR" as the search string. This will bring up several different sized overflow boxes that can be used with bulkheads. Although it might be tight on a 29g use maybe 18" or 24". You can go to the vendors website and order a lid separately.

Get the largest one possible that way you can transfer it to the new tank. Search for "bean animal" here on RC. Plumb the box for a bean animal now (3 holes) or maybe just use two holes now (hebie overflow or glass-holes style) but spaced so that you can add a 3rd (bean overflow) when you go to the 75g.

They are very nice quality. I'm fixing to change over a glass-holes 1500 gph box to one of these and add a 3rd hole so that I can run a bean animal on a 90g I have.

the bean animal is also called the silent fail safe overflow http://www.reefcentral.com/forums/showthread.php?t=1541946

I used a 1500 on my 29, it's fine. I don't like 1" drains, and refuse to be at the mercy of a single drain. Is it dead silent, no. It is fine for the location I keep it.

Thanks for the input guys. Well, personally I always felt bean animal was too complex for me and this is my first time building an overflow for a sump so I have no previous experience with the amount of noise that a glass-holes kit, durso, or herbie makes... Perhaps I'll take another look into it though
