Dr Tims Ammonium Chloride Cycle New Aquariums 120ml

Very happy with this as always. Decent enough value, there's enough in the bottle to fully cycle at least an 160L tank. The directions are straight forward and you can find them on the dr tims website. I've tried other household ammonias in the aquarium before and find even those that say they are dilute ammonia only do not always work - varying concentrations perhaps. This works brilliantly for me because you simply add one drop per litre in the aquarium to increase the ppm by 2 when directed by the online guide.

Does what it claims to do, good quality, really speeds up the tank cycles.

Straightforward to use (just count the drops). Just be careful not to add too much as I found this more potent than it said on the bottle.I used this to cycle a tank - a bit slower to start than I expected but eventually managed to cycle the tank and fish are in and happy.

Probably the best way to cycle a tank as your not causing any harm or stress to your fish. Just not so sure it's as quick as advertised, which wasn't an issue for me as I wasn't in any hurry. However tank is now cycled and water quality perfect for fish. Still going to take my time building up the fish load just to ensure good bacteriagrowth.

Easy to use and helped start the nitrogen cycle.

This product is by far the best on the market. Although the process to complete will take around 20 days regardless of what instructions state which is still a great result. I used this product with Dr Tims One & Only Nitrifying Bacteria and got results needed.

If fish cycling from scratch have patience, it will happen but maybe two plus months

Did the job along with the "one and only" bacteria, worth every penny.
