Is there a test that tells you specifically if there is unsafe levels of bacteria in your water? I usually keep the chemistry in check, but high PH for some reason has always been a problem.
The water looks clear, but I know looks can be decieving, so I was wondering if theres a way that you can test the water for high levels of unsafe bacteria.

If your test shows no free chlorine and the ph is not in the o.k. range, bacteria are growing. Exponentially.
