Trying to reseal the front of my display tank before I get it set up.
The existing silicone was coming off and contained black mode spots.
I cant seem to find any silicone that is 100% silicone and says it aquarium safe or is water proof.
If your read the small print -ALL that I find state "not recommended for continuous under water use".
I can find small tubes at local fish shops but only 3oz., and I tried that, not happy with results as you can not get an even application.
