Because I use a shitload of sodium hypochloride and still have unstable PH and can't miss a day or the water will go to shit, I bought some TNC MycorrHydro and TNC BactorrS13 and the next rez change I will try using these instead of hypochloride. Hope it won't make a mess and kill the plant. If you have any experience with these products, you are free to shoot advice.
