FloraKleen Res Change in Aeroflo

Hello,

Newb here. I am running an Aeroflo 20 and was curious about using FloraKleen during the reservoir change. Should I add it to the nutrient solution and let run before emptying the reservoir or should I drain the current nutrient solution, run FloraKleen with plain water for a few hours and then drain it and add the new nutrient solution? Any help would be appreciated!

According to the label it would lend one to believe you can add it to your existing solution run for awhile then pump out and replace with fresh nute solution or atleast that is what I took from the label.
Anyone using this product?

I use florakleen. drain and run with reg water for a few hours, then refill your nute soup.
where do all those flushed out salts go? into the water and they will increase your ppms...
so if you don't drain your nutrients, your 1250ppm spikes to 1500+ and in aero where any
change is instant ohh boy watch out!

also when you harvest i recommend drain and refilling your flush solution (i use florakleen and water)
4-5 times during the last two weeks or so
