If they stopped making prime I would throw the biggest hissy fit. I bought 2 500ml bottles for 22 quid off vitamin grocer. 5ml for every 200 l of water I change means that for that price with free delivery it batters all other dechlorinators. Api is good but I wouldn't use it over prime as it doesn't go as far or detoxify nitrite and ammonia. You don't need another product to make metals safe or remove chlorine. Prime is it all in one bottle.
I should work for seachem lol
