I was preparing to add a new fish and decided to test...

    I have 3 test kits available for sale (calc, mag, alk). I bought them hoping I could use them, but can't since I'm colorblind and can't see the transitions well.

    Hey I was wondering if anyone has an answer to this, but whenever my alk fell to ~8.5 dKH I ended up having a higher pH (8.1-8.2) for a day or 2 before my apex corrected the alk to 9. Whereas when the tank ran around 9 dKH, pH was running around 7.7-7.9. From the reading I've done the opposite...
