Well i got the bug and want a larger reef tank. My 10 gal nano has been great, but i'd like a little more room. So, since i had a 29 gal laying around i thought i'd do some moding, transfer everything into it and see how it goes. For this tank i wanted no equipment in the tank. Keeping it simple and clutter free is the goal. I decided an external overflow would be perfect, and since i got a dremel for xmas, this was the perfect project. Here we go!!!

Bits used:

Cut away the plastic molding and used a sharpee to mark where the cut would go:

Next using the ballpoint bit i made a groove along the line:

Using the bullet shaped bit, time for the cut:

All done, easy as pie:

The washers leaked, so i got these. They work perfect:

Cutting the hole for one of the bulkheads - lots of water!!

Teeth being cut out of acrylic. I'll use a set screw to attach this inside the tank to the back glass. This way i can remove it for cleaning if need be.

Filling up now for the leak test. I'll run it for a few days with FW to work out any kinks that may arise. Next week i'm starting on the DIY pendant to house my 250w MH reflector and bulb. I'll put up those pics as i go!! Thanks for looking.

I'm interested in how you cut the glass using a dremel..... how would you rate the task? easy, hard?

I ask as I'd like to enlarge some previously cut holes in a tank of mine.

Looking good, hope it all runs ok for you.

Just a quick bit of advice in relation to the leaking washers on bulkheads.

Since they are normally a permanant addition I was advised by a tank builder who drilled my tank to just use sealant. Especially since he found a lot of rubber and plastic washers rot over time, especially in saltwater.

I did and have had no problems.

I'd rate it medium-easy. I was a bit scared to start, i didn't want tiny pieces of glass all over my table and i wasn't sure if the tank was tempered. After getting about an inch into it, it really went quick. Then i thought, wow this is so much easier than i thought it would be. I wouldn't hesitate to do it again.

I thought about that. But since it would be very easy to drain the overflow box, i decided on the washers. I would like the option to take everything apart and clean it if necessary.
