This is indeed the pH, from tap. Tried several faucets, and more then one meter. This was confirmed by my local water supplier as 'within guidelines', apparently they receive a lot of calls on the issue from aquarium enthusiasts. So I picked up some distilled water and the pH of that was 7.5 (edit: 6.0 after letting it sit out for 2 hours, ppm: 001), but its $1 per gallon in 1 gallon jugs. I haven't had any success yet finding an RO supplier, and am not in the market for a RO system myself. My question is: Should I use the distilled water and get the pH down to 6.5, or is the 9.9 tap pH forced down to 6.5 fine? I did not know if a 'threshold' of high pH is unhealthy for seedlings/clones due to all the pH down I would have to dump in to lower it to 6.5, and should use distilled water for the first few weeks, then move on to the adjusted tap. Thoughts? edit: Tap water readings PPM with no nutes/pH down is 242.
