I try to calibrate the monitor every few months when I remember.
Today's readings, I'm just including the red flag ones from yesterday;
dKH 5, dropped by 1pt
Ca 350, went up 5ppm
Nitrate 11/10 went down by 10 or 11 pts with the WC, tested with monitor
phosphates; 1st test 0.01, second test 0.17. I'm taking the second reading as valid.
I dosed for Ca yesterday, and dKH today, but I guess its not doing much so far. I am going to go ahead and do that other 25g WC tomorrow. The water change we did yesterday was about 1/8 of the total water volume.
I've never really battled nitrates before. I've read some serious accounts of some brutal battles, but I've never had one myself. I think the highest I've ever had for nitrates is about 30ppm in any tank I've had.
I'm hoping one more WC will bring phosphates and nitrates quite close to 0. With the Ca reactor online I'm hoping dKH will slowly start to rise to the 8/9 dKH I like to see. Once I start to have to top off again via my kalk. reactor I'll start to see the Ca. rise to the 400/420 mark I tend to keep my tanks at.
