what threw me really was,there is a short video on youtube on setting up a pressurised system and they used "bubble counting solution" if they had just said water i wouldnt have needed to post many thanks.
Hi tyke,
That's what UKAPS is here for! Don't feel embarassed about asking any question, most people on here love answering the easy ones anyway (or is that just me?) I know, I've asked many easy questions with obvious answers and then thought: daaawww but they love answering them!
As LD says just simple tap water is sufficient, I don't know why but I always use purified water, or distilled if I can find it. I bought the purified from the chemist (5ltrs £3.50) for mixing dry ferts to a liquid, I asked for distilled and they said purified was the same! I said it would only be the same if purification was acheived by distillation she just looked at me blankly so I took it and said thanks. That aside, tap water will do in a bubble counter but not in a drop checker!
