Useful for starting a new tank
It simply replaces all those starter kits as you can double the dose for a new aquarium to boost the biological filter. What a brilliant product! My guppies are happy with this.

So far, so good
I was having some issues controlling nitrites. Used it, two days later, down to zero and stable. I don't see any issues with my Ph, fish, snail, shrimp and plants. I'll keep dosing the water as instructed.
