Re: [APD] Speaking of Using Color Test Strips
I like using what used to be EM Science ColorpHast test strips here at work.

Why do I like them? You can leave them in a weakly buffer solution, like
some of our tanks, for 10 minutes to get the full color change. They also
have between 2 and 4 color pads on each strip to cover the range. You can
also get a very narrow range set within the pH values we most typically use.
Here is the link:
I know tinyurl exists but I haven't ever looked at it yet, so just copy it
all and paste.
