Right Ammonia

[Toolenaar]

So im about to start a fishless cycle, and I was looking around my parents house if they had some ammonia. I found 2 bottles of the same brand on one of them I found a price tag with fl(old dutch coin) on it so that means it was bought in the pre euro era, so over 10 years ago. It says ammonia in solution <10% and when I shake it lot of bubbles appear but I cant really call it foam. Is it save to use this ? or should I go find some new.

I would not risk it buy a new bottle.

Agree with Guppi. Ammonia solutions will slowly lose ammonia over time as it evaporates into the air. Not worth the risk for a few Euros.

Buy a new bottle. it isnt costly & could save you some heartache over using old stuff.

Agree with the others. WD
