DIY Overflow???

Hey people. Can anyone help? I am looking to drill my 210 on both ends. I have been trying to find the right overflow boxes. We have the traditional acrylic overflows the height of the tank. The other is one that I saw on youtube from Glass-holes.com, its much smaller and shows its very efficient. Im looking for pros and cons of both and any info?personal experience? thoughts? and suggestions would be greatly appreciated. Also any place I might find someone who does acrylic work? Thanks... Rich

 

Have you thought about a hang on back overflow? I am loving my eshopps overflow

 

In the past I have used an H.O.B. overflow and constantly had issues(not that specific brand). The last tank I setup was reef ready with built in overflows and for me it was peace of mind that I wouldn't lose siphon while at work and come home to a flood. Do you ever have issues?

 

yeah, i could never trust a hang on overflow... its just too much of a risk, maybe if i had a smaller tank, then it wouldnt be so bad, but 100+ gallons of salt water on my hard wood floors would make me sick..

 

to drill your 210, you need a diamond drill, a drill,

depending on the size return and drain you want,is going to depend on the two bit sizes you need, on my 150 i have 1" return and 1 1/4" on my drains with a mag 24 for return...

drilling a tank is not hard, takes patience and a steady hand, but you just run water over the area your drilling and go slow, there are tons of how-to vids on youtube for tank drilling..

100% drill that 210 over getting hang on overflows..

 

the pros 100% outweigh the cons in drilled overflows and hang on

pros:
NO WORRY OF A FLOODED HOUSE, THE BIGGEST PRO EVER

cons:
costs more, but most fish stores will drill a tank, if not most any glass shop
on that size tank your gonna need a dual overflows, again more money
takes up more space in the tank, depending more on which overflows you get and the way you set them up..

But again best of all, with drilled overflows, you dont have to worry about the power cutting off and loosing siphon, if your on a budget, it will be cheaper to get a hang on probably..

 

have you ever seen the very slim overflows from glass-holes.com? I was thinking about going that route, but wanted to see if others have been succesful. I will prolly run 2- 1" drains on each side and either drill holes in the upper corners of both ends or just run the return over the back. My pump is a reeflo dart. That should keep the water moving.

 

That should work great. If you are going to drill, may as well drill the returns as well. It's a cleaner look, and makes it easier if you want to put on mesh tops.

 

Stop!!! First are we talking a glass or acrylic 210gal tank? If acrylic, you don't need a diamond bit & it will smoke it if drilling acrylic. If it's glass you better call the tank mfg and make sure it's not tempered glass.

 

Second, acrylic will not adhere with silicone. If the tank is acrylic, then you will be using acrylic glue (which is more as a solvent), and it fused the acrylic. If it's a glass tank, then you must use a plastic or of you are really good glass overflow boxes.
