Seachem Laboratories Prime 1L/34... vs Black Aquarium Silicone Sealant ...

Seachem’s flagship product prime, allows me to do that. Highly potent. Also never expires.

Use this regularly to keep my 30 gallon aquarium stable. The aquarium is stable, i rarely loose a fish. From adult breeding pairs to their fry.

Prime is nothing more than snake oil! Don't buy the hype. The product i got was not sealed, it smells nothing like the bottles i have had in the past.

Tube of silicone itself was easily opened above the threads with a razor blade. Clamped the outside. Took a bit to get efficient with it - you need to work quickly before it skins over.

The stank goes away as it cures, i promise. The vinegar odor is much stronger than the ge brand stuff you buy at lowes.

Buyer beware this seemed poorly manufactured. This is barely enough for one 55 galon tank.
