the kit i bought has a regular ph test and a high ph test. the arowana been living in the tank ever since i bought him/her when it was 5 inches. the jardini is very agressive. I bought a tiger oscar and the pacu at the same time but the oscar didn't make it. i woke up the next morning and the oscar was all tore up. i'm just hoping the jar. doesn't tear up the pacu.
