Cameron Ferguson –
I used this sealant to fix a small crack in my 55-gallon tank. It applied smoothly and dried quickly. The bond is strong and no bubbles formed. My fish haven’t shown any signs of distress since the repair. Highly recommend for both new builds and repairs.

Used it to seal a corner joint in my saltwater tank. It held up well under daily water changes. The seal is clean and doesn’t affect water chemistry. Very satisfied with the performance.
