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.

I have a 55 gallon planted aquarium with fluval stratum as the substrate. Tank water is crystal clear. It is the only one that has ever worked as well as seeding the tank with a used aquarium sponge.

Niteout-ii. Amazing, lowers nitrites easily 25-40% over nite at minimum dose. By far the best nitrite removing and stabilizing product out there. The time it takes to have a zero ammonia and a positive nitrite (not nitrate) reading is as follows.
