I have the nature 2 system. Is the BBB good for my pool? My FC almost always reads 0.5, the pool store where I take my water to be tested told me it will always read low because of the Nature 2.This is my first year with a pool, so I believed everything they told me. Not to use bleach etc..
ps.. I can't use the chart for some reason, I really want to start using the BBB method.
