does fleet go bad ?
i know this sounds stupid but I have been using my fleet bottle for the longest time now, (im finishing it up since i already purchased a pound of kh2p04 in case it runs out).
My tank is a 35 gal running 36X4 watts of Pl lighting, I dose 2 ml of fleet (target is 1.5 - 2ppm of phosphate) 3times a week and recently ive been noticing a lot of GSA on my glass, the fleet is roughly 6 months++ old since i used it before on my 12 gal..
so the question is... is my fleet expired already ? Im thinking of throwing it away and mix up a kh2p04 solution to replace it...
