Hello,
I always trusted to my Hanna Alk Checker. My alk was high and don't fall even with insane coralline grow. SPS doing bad.
I bought the KH Director and the results was low 4.5-4.7. I recalibrate everything using the lab grade cylinders, submerged their filter. Still low - 5.7.
Hanna reported 7.5-7.7.
I tested the GHL Calibration 7.5 fuid and the results was 7.7...
I tested my water with Salifert KH and it's... 5.7.
So, KH Director is accurate. Hanna checker is a piece of ****, I lost so many time, sps and money tried to fix everything. But it just their Alk checker wasn't accurate.
How fast can I rise my alk daily?
