How to remove plexy from sump?

[Jakob]

Im changing a sump i own into an aquarium, aka im removing the plexy that splits up the tank. The tank is all made out of 8mm plexy.

Should i use a hacksaw and try to remove it that way, seems like that would take some time.

Should i use a hammer and just bang the glass inside, although i am afraid that the rest of the tank could break.

Should i try to use a carpet knife to cut the silicone (i think it is silicone atleast, i didnt make the tank myself), i tried, without much success.


What would you do? BTW the tank can have a few scratches this is a breeder tank.

I assume the tank is glass and the dividers are plexiglass. If this is indeed the case, cut the silicone bead with a knife and work to free the plexiglass dividers. Once you get them out, clean up the remaining silicone with a razor blade.

i agree with BadOleRoss , when you cut the silicone around the edges it should be easy to pry the dividers out.

a couple of waves with a heat gun and it'll come off like butter.
and the silicone shud adhere and come off like rubber strings, keeping the heat low and disperse is key
knife or goof-off works too, just dont forget to rinse using solvents.
