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.

Combined with regular water changes this product keeps things nice and clean
I was sceptical at first as it's hard to prove that it was doing much as I began using it after resurrecting a tank that was left to wallow by a colleague. How does one know which of the cleaning products and techniques are keeping things clean? I recently ran out of this and it’s taken me about a month to get round to getting some more. In that period the tank hasn’t turned into a jungle but I have noticed that it is slightly dirtier than when I was regularly using this. The cap has a built in measurer, I use a cap full once a week on a medium 50 litre tank with 1 goldfish and 3 snails in. Combined with regular water changes this product keeps things nice and clean, and even when I’ve missed water changes – using this helps maintain a reasonable level of cleanliness. It’s priced the same on here (£7.98 at time of writing) as the smaller bottle is in my local pet store so no complaints there.

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.
