"Great Stuff" and live plants

[UncleChester]

Thanks!

How bout' this stuff, the clear silicone I will be using to stick my egg-crate & great stuff backround to the tank:

GE Silicone | GE Silicone II, Window & Door Sealant, CLEAR, 290 mL | Home Depot Canada

You're in Canada and probably have a home hardware nearby, so I'd look at:

Home Hardware - SEAL, SIL MULTI-P CLR 300ML 3PK

available singly as well and cheaper than GE silicone II. It is "clear" and aquarium safe.
