I spent a long time doing water tests in all the tanks. It was past time.
Anyway, below are the results. This is the first time I have done all the
tanks since we got the RO
unit and I have noticed that the stability of
most readings has increased, I use less salt per bucket for the same
salinity and the ph
is staying at 8.5, using no additives on most of the
tanks. The challenge comes in coming up with an explanation for the
46 gallon tank. It has been "cycled" for 3 months now. But, there is
something definitely WRONG, as nothing will live in the tank past an hour.
As you can see, all the readings are normal except calcium....there is none.
I have checked the test against another test kit, plus used the same for the
rest of the tanks. What could take the calc to zero and yet not affect the
other readings? Substrate is gravel, there is some hirocks baserock in the
tank. I have checked for iron toxicity and had the LFS
test for copper...zilch.
I added the results of the RO
water as well. In addition to what is on the
chart, the GH
showed no reading, which they said meant less than 20 mg
