Silicone

[Fishkeeper26]

I have silicone that say it's 100% silicone, but also says it's mildew resistant. So is it aquarium safe?

I would not use that since some chemicals used to make it mildew resistant is toxic to fish, look for silicone that states aquarium safe.

The window and door stuff from 3M is what I use. There's a version out that does say 100%, but has mildew reducers in it and I wouldn't use it.

A common silicone that is used is GE silicone 1 or 2, but only the window and door one. These are easy to find, and I got mine at wal-mart. Just make sure it has time to cure completely. By the time I set up my siliconed refugium, it would have cured for 2 weeks.

Thanks! I'll look for a different brand probably the 3M

There's a brand called LOCTITE that I use, in the little tubes (not for a caulking gun) that says aquarium safe on it and I get it at lowes.

I have also used window and door silicone 1 from walmart.
