i noticed a little bit of this brown slime that was on the tips of my roots so i drained the water in my aero res. gave the resevior a quick wipe down and filled it back up with clean water i then added some hydrogen peroxide along with some super thrive. the next morning i went out to my hydro store and got some sm-90 i added that to my resevior at 2ml a gallon. Today i woke up and checked the roots and there is still a little of that brown slime so why question is how long before the sm-90 starts to take effect? Also should i add sm-90 everytime i change my resevior? Last is this the begining stages of root rot or is this just nutrient build up from not changing the water as often as i should
thanks
