Except API.jcardona1;4434707; said:i think youll find that most people use seachem Prime. one bottle will treat more gallons than any other brand out there, so it's cheaper in the long run.
API makes a tap water conditioner that is more concentrated and cheaper than Prime.
Prime, 5ml treats 200 litres, available online in Australia for about $20 per 500ml.
API Tap Water Conditioner, 5ml treats 378.5 litres, available online in Australia for about $10 per 473ml.
The API conditioner doesn't claim to detoxify ammonia, nitrite, or nitrate, but does claim to detoxify heavy metals.
