Removing glass baffle in an operational sump

[hqgc]

Hello everybody,
I am trying to remove one of my baffles in my sump. The sump and tank are up and currently running. I have tried cutting the silicone with an "Olfa" knife but cannot get the thing to budge!
I was wondering if it is an option to break the glass and then remove it that way. I am concerned about getting broken glass into the system ( pumps,etc.)
Any other ideas?
Thanks

I've done this, it's kind of a PITA but you should be able to get a clean break. Score right down the middle on one side and then smack the other side on the score line with a screw driver handle or something.

"Score" down it with what?

a tile cutter sometimes works ok, do you have a diamond ring around?

A diamond ring , maybe , but my girlfriend would kill me !

Don't use a diamond you'll chip the bloddy thing and never hear the end of it. Use a glass cutter from the hardware store, they're cheap.

Ive never used one for that purpose but i know people who have without problems, was just a sugestion.

How much of a gap you have between the edge of the baffle and the sump wall? If there is a gap you could try using thin air craft cable to saw the baffle out.

Thanks for the input!
I think I will pick up a glass cutter and try that route. I will update the D.I.Y. crowd when I am done on how it worked out.

Then it isn't a real diamond.....and then you WILL hear about it

Been there, done that. Real diamonds cheap quite easily regardless of what the movies say about it.

My personal opinion in the matter is not to cut or alter the glass baffles in an operational sump/aquarium. Why risk the following.

a. injury/cutts/infection etc.
b. increase possibility of damaging the side panels of the sump (while its still holding water)
c. small shards of glass left in the sump afterwards.

I'd purchase a new tank/sump, make the conversions your intending to have and then replace it with the existing one. It's a little more effort and cost, but why take the chance.

Ended up using a hammer to break the glass. Worked fine and everythink is ok.
