OOOoo test kits. I had not thought of those.
You want a liquid test over the strips. Strips are often inaccurate and only provide a range not an actual number.
That does not mean a liquid test is always that easy to read, which I would say is the con of liquid. API master freshwater test kit: Always a good choice.
