Right equipment

[ClowinRound]

Would this cutter be the right cutter for the job? I always see the type that have the diamond dust all around the cutting edge, so just wondering if it will still work.

Yes that will drill glass just fine

Save a couple bucks and buy one from Glass-Holes.

I just got 2 on amazon for less than 10 bucks

So I finally drilled the holes, BUT this happened. Is it good or is it too damaged and just get another tank? Thanks for the input.

I'm worried about these 2 spots

Well what side is the flange going on? That's the side that determines seal....regardless which way it goes in.

That's what I was thinking. That damage is to the outside. So the inside of the tank chipped very little as seen on the first picture, the bottom half. I was concerned with failure from a crack though I dnt see anything coming off the edges. I'll inspect it closer.
Could I use silicone?

Could I use this to address the small chips on the glass?

The bulkhead has a decently large oring -
If you are really concerned with it, use some reef safe silicone on the back side when you put it on and let it cure. But it probably won't leak.

This the right stuff used for rockscape?

That's what I used mixed with super glue gel. I made some crazy rock over hangs with it. Just give it a lot of time to fully cure before moving it

Look into using 3M Co 5200 marine adhesive. It's really slow to cure fully, but once it has, it's nearly indestructible!
