Which Ammonia?

[huckFIN]

I was going to buy a bottle of ammonia today to begin my fishless cycling. I understand that this needs to consist of just ammonia and water with nothing else (such as detergents etc) added. As the particular bottle I was looking at didn't state the ingredients on the label I didn't risk buying it.
Can anybody recommend a particular 'brand' of ammonia that is safe or an ammonia bought from a particular chain store (UK) or should I just keep looking until I find a bottle with the correct ingredients listed on the label?

try boots they sell a pure household ammonia for a couple of quid. needs to be one of the bigger stores for them to stock it though.

homebase also sell one, can't remember what they call it exactly.

good test is to shake the bottle, if it foams it's no good, if it doesn't you're probably ok.
