I always figured the ones to immediately avoid would be the bathroom/tub versions where they're subjected to moisture daily. A window only gets wet when it rains!
I would think good filtration would take out any cides or chemicals ater a few days..I have used many silicon brands all marked 100% silicon and have not had a problem..
I used to be a sales rep.and Coach, not sure where your coming up with mildacide?.....merriam-webster online shows it as "mildewcide" That being said, I hope you're right about it not killing us.....OR fish!
This tank was to be a non-planted, so I'm hoping things will work out fish-wise. It is extemely frustrating to see that this product doesn't have the "mildewcide" labeled. Why isn't that infomation they'd choose to let us know?
