How much is it to get glass cut for baffles for a sump?

My friend at school was asking me how he can add a sump for his 55gal eel tank, he wants to add some corals. Of course I’m more happy to help him, but sumps are pretty expensive, so I suggested a diy sump. So where would be a good place that’s pretty cheap to cut some glass out for baffles, I’m pretty sure he may want to use either a 20 gal high or long.

Thank you

Acrylic needs expansion gaps too. Take that into account for the dimensions. Acrylic will swell when submerged in water. I've seen a post where someone broke the glass tank because there wasn't enough room for Acrylic expansion.

My preference is for 1/4" minimum glass baffles, if its a glass tank. Glass baffles will actually make a glass sump tank stronger.

I built a 75 gallon sump with 4 chambers using 1/4 inch glass. Binswanger cut it for free. It was a slow day and the guy was intrigued with the concept. Have it cut an eight inch shy on the width and use clear aquarium silicone to keep the glass in place. It has worked like a charm for ten years. The cost was nominal especially compared to everything else you will wind up buying. Do it right the first time.

If you are using a glass tank, glass partitions will hold up better. I've used acrylic with glass before, but the silicone doesn't adhere to the acrylic that well long term. If you go that route, make sure you use something better than standard silicone.
