the only issue I have with it is that it turns the water the same colour
as a positive ammonia reading with my nutrafin test kit - nowadays I add

You may wish to switch to another ammonia test kit, one that isn't Nessler
based.

The two part test kits usually meant for sal****er will give you a much
more accurate reading regardless of the tannins in your water. I don't use
anything else now because, well I have both fresh and salt, but also
because Prime--an excellent water conditioner made by Seachem--produces
false positive result with any Nessler based ammonia test kit.
