Dr Tim's Aquatics One and Only Live Nitrifying Bacteria for Cycling Reef and Nano Aquariums - 2oz / 60ml

Used with Dr Tims Ammonia treatment my tank fully cycled in 9 days. Will definitely use again in other tanks set ups.

I used another similar product to cycle my marine tank quickly. I added two clown fish but had issues with ammonia levels long after the other product stated that the tank would have cycled.I didn't want to lose my fish so thought I would give Dr Tim's a try, very good product after 4 days my ammonia levels were down to a safe level for my fish.I would definitely recommend Dr Tim's, expensive for the size of the bottle but well worth it.

Added it to my tank as it definitely helped the cycle would really recommend. Bit small but I would say it’s better that api quick start

Excellent product, establishes & maintains healthy marine tank.

Small bottle for the money

I does what it says, I love it

Great product, helps cycle tank very quickly. Just make sure you have a reading for Ammonia first before using as otherwise it cannot work.

So I paid £15 for a bottle that looks bigger in the asvertised picture than I actually thought I'd reveive.In the uploaded pictures, the smaller bottle is what your receive for £15, however for the same money from a different seller in a aquarium shop online, your get the same quality product in a huge bottle. This bottle your get only does 110 litres.Arrived and I think to myself well that was a waste of money, and felt instant disappointment.

I cycle all my tanks and if you follow the chart it works 100% of the time. Wouldn't use anything else.

I recently had to restart my tank with an infestation of Aiptasia. and I went to Dr Tims for the second time. to save me.

I have cycled my red sea max nano with following the instruction, but it did not match the results I was expecting and I had to cycle the tank for a longer time than expected. Therefore It s difficult to judge if it is good or bad, but probably I will not buy again.

I filled my tank with de-chlorinated tap water, put some old lace rock in, tested my sump/plumbing, and checked my ammonia the day I added it and there were substantial levels. here is an excerpt from my tank log.8/20/2016 – 9:00 pm - Dr tim’s added to tank at night.8/21/2016 – 8:45 pm - bluejaw triggerfish added.it is now 3/13/2017 and I can say that after seven months I have not experienced any mass die off of fish due to a tank crash or other cycling related issues. Plus my bluejaw triggerfish is happy and bigger than when I got him! I would recommend this to anybody looking to start a saltwater tank faster than the traditional method. (but I did kind of rush it!)

Great product!
