i live in a area that is suppose to have fairly hard water. not sure what the ppm is yet but just ordered a ppm meter. Would it be ok to use tap water that has been run through my britta filter? and do i need to do anything to the water like let it sit out 24 hours so the chemicals can evaporate? are there any tips or tricks that i should know about when choosing water? not sure if it make a diff. but will be using hydro/aerpponics.
thanks in advance
