After debating & thinking & chickening out a few times, I finally did it. I cut a u-shaped piece off the top of my tank so I can create a siphonless HOB overflow.
The finaly push came when I had a minor flood last month during a power out (one of the siphon quit); so this is it, no more siphons.
I cut the glass using a diamond coated glass cutting wheel (from Lee Valley) in my Dremel. I practiced on a scrap piece of glass I had & the cutting was really quite easy. I flooded the area with water and went slowly with the Dremel, going over the line lightly & letting the tool did the work (no downward pressure). I did the cuts (a 6"x1" slot) in about 1 Hr, and my tank is still intact!!
I am modifying an old A/C HOB filter for the overflow box. I carved a matching end out of PVC pipe to go into the hole where the pump normally goes (using table top router & my trusty Dremel) as my bulkhead. I've cut away extraneous parts of the HOB, now all I have to do is to bend the front a bit to make it look pretty and silicone it in.
Testing for leaks Wed.!
