After 12 weeks of use, tank looks the same, worthless. All affected corals were removed from the system and eventually died. It smells like sterile water honestly.

This is the only bottled beneficial bacteria that i trust 100% to cycle a tank. Helps keep a cycled tank cycled. I have a 55 gallon planted aquarium with fluval stratum as the substrate.

Nite out ii is the most consistent bacterial addative i have ever used for cycling aquaria. Amazing, lowers nitrites easily 25-40% over nite at minimum dose. It’s literally instant cure if you have a an ammonia or nitrite spikes.
