Aquarium silicone

[Eric P]

Why can't I use regular 100% silicone in my sump? I have used perfecto aquarium sealant which on the container states that it is 100% clear silicone rubber. Sooo what is the big differance between aquarium silicone and standard silicone? Both are 100% pure silicone. Is this like when the southdown bag says not for aquarium use?


Thanks, Eric...

If it has any kind of mildew perventive in it dont use it.


Maybe some one else will chime in but I wouldnt use it if it does

pretty much what Jeff said. as long as it does not have any mildew preventatives or even colouring agents, it should be fine.

Not to beat the dead horse but I use 'GE Silicon II Window and Door' for my sumps and it has always been sucesfull. Just make sure you don't get the 'bathroom and kitchen' tube because like everyone said, that has the mildew resistant stuff.

As long as its 100% silicon and milder resistant you should be good to go

I'm repairing a leak in my 29L right now to become a refugium for my 37. I thought along the same lines about un colored 100% silicone. I purchased GE's "Silicone I Door and Window". I'll let you know how that works. BTW any reason for siliconII over siliconI?

Most of the clear stuff should be OK but don't let the "100% silicone sealant" fool you, silicone sealant is a compound.

I just used the DAP 100% silicone. Heard it works just fine. Picked it up at Home Depot or Menards.
