Knock Out Household Ammonia, 500 ml

Strong, effective cleaner that tackles grease and stains easily. A little goes a long way and it leaves surfaces fresh and spotless. Great value for money.

Good cleaning product

Did the job. I didn’t use it the typical way haha. I used it to cycle my new tank. It worked perfectly. Delivered on time.

Bought this to start an aquarium cycle off. It worked very well. There's none of the tell tale signs of there being anything other than ammonia in the solution. Based on the dosage I needed to reach about 2ppm (mg/l) of ammonia, I'd say that the strength is about 9.5%, due to the fact I needed 2.7ml to reach the concentration in my 120l aquarium. Now I just need to figure out what to do with the remaining 497.3ml of the stuff. Oh and don't be tempted to give it the whiff test, unless you like extremely unpleasant sensations in your nasal passages. Maybe go outside to pipette out some too :)

Great for weeds and maggots do not smell will take your breath away
