this should be in a different thread but,

I would say no it isn't because of the words "that also provides a mold free product protection"

The only way to go mould free is to have inhibitors in the product.

I wouldn't chance it. look for something that says aquarium safe and spend the extra 2 bucks.

I think confusion lies in statements like 100% silicone. Silicone is a synthetic compound made up of many things so saying 100% silicone really means nothing in terms of what's in it. Kind of like saying 100% rubber or 100% plastic.

I've used GE Silicone II Window & Door Premium Waterproof Silicone. I've had no issues with it, though I did let it cure for two weeks prior to submersion in my sump. The stuff I used indicated that it was mold "resistant" but not that it was mold "free."

People that crashes using GE silicone is because they don't wait 24-48 hours before putting back their saltwater.

:fadein: This is Proper Aquarium sealant Nuflex 333 made for aquarium use and repairs. I bought it through my local glass shop,300 ml tube is 10-12 bucks. Not cheap but I know I'm not going to have any problems.

Exactly. That, and the toxins in the new formula :razz: Mostly the toxins though..

facepalm

:suspicious:

Yep. I waited 3 days. Still crashed

Anyone know if this is safe, no mention of mildew resistance? Otherwise I am going to coat the bottom of my new nanao with it in a bit ...
