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.

The best bacteria around

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.

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

I added it and I have waited 48h, I have watched youtube videos on it and there should be a drop in my ammonia levels.They have staid the same. I am still waiting for a change in my ammonia levels.

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

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.

Small bottle for the money
