Hey guys I'am new to hydro and will be starting a ebb&flood soon and I read all I can about it.like to ask what are the temps of the water?What did you disinfect the hydroton with?Housewhole bleach is not pure,has alot of fillers in it.Example TIDE DETERGENT 20%phosphate the cleaner and 80% peanut shells.So rainse then 3 or 4 times let them dry and the 5th raise try a small amount mirco in the rainse before using them.I know when I add micro to the water the PH go's down.Lots of PH water.Well thats My take on it.PEACE
