High Range Ph Test?

I just use the normal range test kit but I've seen it go an indigo or navy colour with ultra high pH. That only happened when we had a new filter installed in our water filter. I don't think you need high range if your water supply is from the mains and is suitable for human consumption.

I use Aquarium Pharmaceuticals and it goes up to 7.8 which is a rich blue colour similar to the colour on the posts where it says "Quote" or "PM".

My tap water is 7-7.2 and very soft, so AP is all I need.

The water from my tap has a pretty high pH sometimes, so I have to use the high range. But if your pH isn't normally that high, then you should be fine without the high range drops.
