As someone who's resealed multiple aquariums over the years, I can confidently say this Aquarium Silicone Sealant is a game-changer. The quick curing time is unbelievable - I applied it to my 55-gallon tank and could smooth it out easily before it started setting in just 5 minutes!

The low odor was the biggest surprise. Unlike other aquarium sealants that make your eyes water, this one barely had any vinegar smell. I actually did my sealing indoors during winter without any issues - something I'd never dare try with other products.

After full curing (I waited 48 hours to be safe), the seal was incredibly strong yet flexible. My tank has been leak-free for months now, and my fish show no signs of stress - proof that it's truly non-toxic.

The only downside? Some tubes arrive without nozzle tips (happened to one of my two tubes). But even cutting the tube open worked fine for larger applications. For the price and performance, this is hands-down my go-to aquarium sealant now.
