Liquid plant food.....can it lose its potency after a number of years???
Hi all....I was wondering if liquid plant food, such as Flourish, can lose its potency after a number of years?? The bottle I have is, Im guessing, at least 3 years old.....I neglected my tanks that long, so thats why I have a bottle of it that is that old......Ive got my tanks almost completely void of BBA, and they are looking better day by day......do I need to buy a fresh bottle of food????Thanks for looking........
