i usually change out every week. i let it go for 2 weeks this time around (taking the advice of some) that said there was no need to change weekly. as i stated i just did a res change yesterday. i do dose it with h202 every few daysRoot Rot or Pythium is a fungal disease, slime on roots is a bacterium, how often do you change that rez...? weekly ...? as the chlorine should kill the bacteria
is this a substitute for h202? or would i add both?HTH Shock 'n Swim. Mix 1/4 - 1/2 tsp per gallon to RO or Spring/Distilled water (let stand for 1 - 2 hrs then shake very well) and add this diluted mixture to rez at the rate of 7.5 ml/gallon every 4 - 5 days and at every rez change. Problems will be eliminated.
