Hi peeps,I am quite anal when it comes to PH and as the local water went up to 9.1 I was adding more and more vinegar lemon,juice etc then after reading a posting about vinegar best put on chips,I was shamed enough to drive to the local (long drive) grow shop and purchase a litre of PH down,and was miffed to have to pay 20€ for it,however I was even more miffed when I found out I could get pretty much the same thing from the supermarket for 4.20€ for 5 litres,comments on these and other ways our hobby has been turned against us are more than welcome my friends AAS signing out
