DIY internal glass overflow box with teeth

So as I was starting to take off my overflow, I was shocked to see that it came off wayyy to easily lol well that's because the silicone I used. And of course because regular silicone won't adhere to acrylic. I literally just pulled lightly and it came off



So then I started thinking well maybe I'll just make my own overflow box...but then I started thinking again....I wanted teeth in my overflow but I didn't want acrylic, I wanted it to be glass. So I got out my diamond whole saw......yes a 3/4 whole saw... and started drilling teeth in my glass overflow. Now I know that teeth on any overflow reduces the surface skimming but I wanted teeth to keep critters out of the overflow box without putting something over it. So this is what I came up with. I know people may have already thought about it or have even done it...but this is my version lol*













Idk how reliable or how effective or not it will be...but if not then that's ok I can just replace it. But I will be testing it out tomorrow.i made it bigger to allow for more water flow into the box because this was not easy drilling the teeth. Trust me I spent all day trying to build this box, but hopefully it will pay off. I started over so many times because the teeth kept cracking and chipping off :headwallblue:


It was definitely an art to get the teeth to look the way I did using a whole saw.
So hopefully I can get some of your guys input and feedback.

Like or dislike?

Good idea or bad idea, but not because of surface skimming.
 
Your right I totally agree with you...but I guess it's more for keeping fish out of the drain lines. Snails will for sure get over. It's just another way I went about making a box that had teeth and will adhere to my glass tank better then acrylic would
 
If you want a glass box, do a straight edge with glass. To keep critters out, design a cover lid that mounts over the straight glass edge.

Its possible to make a glass box with teeth using a wet tile saw, but in the end its going to be very fragile. Its not worth the trouble since you can make a removable cover lid that forms some sort of barrier, (using any suitable material).
 
Try to test it before you silicone it in....because most likely the teeth are too narrow and too few for the job you are wanting to accomplish. Do like others have suggested and go without teeth and a cover or buy some clip on acrylic teeth. Just my opinion.
