GE Silicone Type I Doors & Windows
In general you are looking for 100% silicone with no algaecides in it. This one fits the bill.
When you are looking for some, the key is
must say 100% silicone
must NOT say "anything resistant"..
GE Silicone type 2 has algaecides and UV
protection, so it is NOT suitable.
And save a couple bucks, you can get Type 1 (make sure NOT to get kitchen and bath) from home depot for way less then what Allglass stuff sells for, and it's the exact same thing (for 3$ less a tube).
