the tap water is being sterilized *somehow* and I find it difficult to believe it isn't chlroramine.
I tried blending RO and tap, and it worked pretty well, and it may work great for you. try it and post your results
thanks ya its about as slow as a frig but ya ill just have to deal with it cuz i dont have a ppm meterDo you have well water? If ppms are over 200 dilute with ro I use a 1/1 mix for vegging nutes my water is 350ppm from the tap so I end up about 180ppm. I use straight ro for my flower room. If your filter is slow like mine take a bucket full every morning and night and store some in buckets or tubs...
