API QUICK START Freshwater and Saltwater Aquarium Nitrifying Bacteria 30 ml Bottle

Always works very well for me

had this before very good quality

Another excellent product from API which does the job as required. In this case it's Bacteria to add to the Filter to service the well-being of the tank water when setting up a fresh aquarium or adding new fish to an already established one.

Took around 3 weeks to complete cycle.Do not use to fully stock within the week *Product only for insta stock if your adding a tiny % of your fully stock amount e.g. 1 or 2 low bioload fish.I Really messed up my fish-less cycle for the first 2 weeks (First 2 weeks had relative help -they got a bit confused- Week one added 4ppm everyday ;P lead to Ammonia overdose way off the charts - Week 2 got under control but relative got confused and didn't add any ammonia)By the end of week 2 even with all the messiness bacterial colony for cycling ammonia to 0ppm had developed.End of week 3 nitrates were also 0ppm so i'm really happy that it cycled in under a month.*Really did add the full recommended amount to my tank nearly every other day ;P**My temp was at 26C and pH was 8.2 so probably helped cycle quicker***Saw some comments about refrigerating bottles for it to work - I did not refrigerate the bottle and still worked (kept at room temp ~20C)**** Probably does contain all bacteria you need, by end of first week when the ammonia was probably about 16ppm ;P I had nitrites around 5ppm and nitrates at around 60ppm

Worked new aquarium shows signs of beneficial bacteria after just 3 days.

Good quality

I'm gonna have to get more of this when I get round to it.

Great
