Hey probably not a big issue and i could just use ge silicone 1 but anyone try this brand of silicone? Seems just like the cheapest silicone i could find that lists for aquarium use
Don't see why not. I would personally spend more and get the 'right' thing even if it was just for peace of mind. But small projects or things that are not critical sure.
Hell I have even used the neutral cure silicones under an hour after applying ( in tank use not structural) to no ill effects on any livestock. (air dry 10 minutes then soaked in RO water for an hour then right into the tank)
