I would assume I would drill it from the top down? If I did decide to try it.

Yes, watch a couple of videos. It really is easy, just remember to take your time. There is no rush, and if it takes 5 min to drill the hole that's fine. But looks at over the back too, just to look at all options.

The bottom glass is 1" thick.

I don't think my husband will allow anything hanging over the back.

 

[Katrina71]

He is very picky.

Is there enough room in the bottom in the overflow? Or will you need to drill it in whet ever will be the back of the tank? 1" thick glass will make it even safer to drill.

I doubt the overflow is big enough.

 

[Katrina71]

Hmm. Decisions.

Personally i like the idea of going over the top. reason being is easy to add more pvc for return if needed in two different spots.

As @mch1984 has already answered, along with that kid @

How difficult is it?

As that kid @Musovski and @mch1984 have indicated. Drilling glass is not difficult, at all. A main point most people don't seem to get is to NOT PUT ANY PRESSURE ON THE DRILL. Just let the weight of the drill be the pressure.
There are many videos on drilling tanks and glass.
I'm fairly sure we'll know about what you're going to do before you do it.

 

[mch1984]

I doubt the overflow is big enough.

In that case I would drill a single hole for the return and put a Y in the lockline to divide the flow. One less hole to drill and just as effective.

 

[Katrina71]

Ok. I'll shut up about the tank and read.

 

[crusso1993]

I've had both drilled returns and over-the-edge returns. They both have pros and cons and, at the end of the day, it comes down to what you prefer.

Also, being i work at home depot again.... specifically hardware. i recommend not using the bosch bits. Although Bosch is a great name, they 1) dont have big enough sizes and 2) tend to do a bit more damage than the other bits.

FYI - THK has their own eBay store. If you're not in a hurry, you can get the hole saw for much less money.

I use the ebay ones. Remember they are different sized for the sch80 bulkheads if you decide to go that route.

Good point, I would have forgotten all about that. I could see it now, tank is drilled (all excited) put the bulkhead in......doesn't fit.

Any ice cream left. I like chocolate ice cream and strawberries on top or anything with peanut butter, chocolate and pretzels are also good.
I have no opinion on plumbing. A bought a box that you add water and fish to look pro

NEVER ask me how I know this to be a true story.
