Go to lowes or home depot and buy bottle of Phosphoric acid then dilute. That's all that your ph down is.I got both the strips and a cheap tester, does anyone know of any affordable PH up and down bottles we can buy online?

The strips are fairly accurate. Though it depends on the brand you use how easy it is to see the pH changes...When you get PH up and down, you know that little bottle that says "PH test indicator" on it? My question is, how accurate is that to measure my waters PH? I made the mistake of buying 2 cheap ass PH pens that are garbage..So anway, how accurate is it? Thanks
