Works well, did the job.
I've always been a little worried about using chemicals in the tank, but this stuff was great, along with the ammonia it cycled the tank very quickly, haven't had any problems so far, it's been a week with the fish in and still all readings are as they should be, did my first sand clean and water change today and all is good. This stuff works.

Beware, faulty item
I ordered from from this seller twice and both times the ammonia would not move from 2ppm (dosed with dr tims ammonia chloride) after several days. Then bought from my usual fish store and it knocked ammonia to 0 within 24 hours.I assume the bacteria supplement is either expired, exposed to extreme temperature or compromised in another way.

Quality product, clear difference in water quality after 24 hrs
Was spending alot on the smaller sizes in uk, but including shipping was still cheaper to have it imported, will be back for more once this one has run out
