I bought 100% Silicone Rubber Sealant - Made by Dap - from WalMart. I wanted to buy the GE1 from Lowes, but both Lowes and Home Depot were closed. Anyways, it didn't list it as having Mildew Resistant additives, and neither does the WalMart website.
This is for a sump by the way
Total View of WalMart sealants, it lists others as being Mildew Resistant, but doesn't show it on the dot list. (Mine was the Dap 08641)

Searching more on google, an Amazon sale listed it as Mildew Resistant.
From the Manufacturer
Superior quality tub and tile sealant. Offers long-lasting flexibility and excellent adhesion. Provides a watertight seal around non-porous surfaces, such as ceramic tile and plumbing fixtures. Safe for incidental food contact. Cured sealant is mildew resistant.
Dap 08641 10.1 fl oz; clear 100% silicone [PRICE is per TUBE]
One of the reviews however says he has used it many times...
You're right that sealants with anti-mildew agents added are not aquarium-safe...but this silicone does not have anti-mildew agents added. I've used it extensively in my reef aquarium (i.e. an entire tube this size) with no adverse affects on anything. Yes, the advertising blurb is a bit misleading - they're probably referencing silicone's natural anti-mildew resistance. But the "100% silicone" is the giveaway that this is just silicone. DAP makes a different silicone product called Plus or something that DOES have anti-mildew agents in it.
Ok, so my question(s):
1) Have you ever used it with good results?
2) If you haven't used it, do you think it will be safe for me to use it?
Thanks in advance!!!!
