Review on π Optimal pH Testing Kit by EHM by Warren Hess
Extremely inaccurate
I test the water often because we have an old well with acidic water that needs pH control. I have been using the General Hydroponics test kit for many years and it is very accurate as confirmed by my fountain company. I bought it while waiting for GH delivery. Basically this product sucks, it's so far from being accurate it's not even funny. Don't rely on this product, buy something else and compare the results.
- Easy to use plastic bottle
- Something else
