So I bought a heater, and it doesn't fit in the first chamber of my biocube, as expected. I tried to remove the false floor, but I cant get it out. I heard people say that it takes a lot of effort, and heard about people cutting the silicone, pulling it out, and/or cutting it. Well there's water in it and I don't want to break anything. If I push REALLY hard is there any risk of anything breaking?
Thanks!
EDIT: I just got owned by my mum. It took her like 20 seconds to pull it out.

Darn asian mums.
