Hi need advise.

[Justin4real]

Hello all,

I’m new to this marine hobby.

I’m currently in the process of getting the holesaw on my tank. Only issue I have is holes.

I have two in the right corner. Now I am after enlarging these from 32mm to 45mm. But I also want to put another on the left. The glass tank base does not sit on the stand it has a plastic skirt around the bottom. I was wondering if I can have the hole on the left? As the two on the right are for the drain to the sump tank.

Tank is 240l around 55g

The stand is 1.5” thick under the tank.



Please help a guy out here as I’m holesawing this myself.

This is what I got at the min.

Without ripping tank apart at the min I’ve got the measurements on paper as a guide but I would like to be able to enlarge the two 32mm holes for 45mm for the 32mm bulkheads I have.

I’m just a little worried I might not be able to achieve what I want. A friend has just done his to 45mm but he got it done at local fish shop store. He hasn’t even tested the tank out for water issues yet.

The tank is a Roma 240l

Here is a picture of my mates an he has just stated his sump now. But here are his 45mm holes in the tank.

So to be clear to us, You have holes in the side that you want to make bigger? Your not talking about a hole thru the bottom? Or do you want the existing holes larger?

 

[Justin4real]

I want to make the 2x 32mm holes on the right bigger to two 45mm

And add a single 45mm to the left.

Has anyone on here ever tried drilling the tank like I’m trying to do ?

 

[Matthew Frost]

If it were me I would not try and enlarge existing holes. I would drill two new larger holes on the other side of the tank and use the two existing holes instead of drilling one new hole and enlarging the two existing ones. My experience with enlarging holes in glass has been not so good. Remember to ALWAYS separate your holes by a minimum of one hole diameter.

I have added the marking up I’ve done and the two next to each other are just under the 1x distance. Glass is 8mm think. Not the 6mm I was expecting.
