Tetra No More Algae Tablets - 24... vs Seachem Laboratories Prime 1L/34...

I'm not sure these are good for my fish. Be careful. Algae eater fish work much better.

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.
