OK I have both of these additives. Now my question is, " based on purigens ability to go toxic with some stress coats and kill fish, and chemi-pure's say so flawlessness described on the bottle, which one do I use??" They are both good according to my experienced friends but i need a third opinion; Does anyone have experience using these products. even though I know they work, I'm just scared of the purigens ability to go toxic and I use API stress coat in my tanks.
