I have read a wide variety of articles and differing opinions on this one, but I am going to post this to see if perhaps someone has something that makes more sense to me than what I am seeing.
Bottom Line: My dKH progressively drops throughout the week if I do not dose. ~ loss of .2 dKH per 24 hours However, the corresponding pH change does not drop at a rate that would allow me to dose and keep things level without skyrocketing the pH levels.
For example, please see the below measurements.
Wed dKH - 8.0 pH - 8.3
Tue dKH - 7.8 pH 8.2
Thur dKH - 7.7 pH 8.0
Dose 1 fl oz soda ash solution
Fri dKH - 8.0 pH 8.4
And so it goes... I want to maintain my dKH at 8.0 and my pH around 8.3 +/- .1. But if I made small daily additions of soda ash, my pH would climb higher than I would like.
Is there a way to maintain the dKH where I want without the corresponding increase in pH?
Other levels that I maintain consistently are:
Salinity 1.024 / Temp 79 / PO4 0 - 0.1 / NO2 0 / NO3 0 - 0.1 / Ca 430 / Mg 1300 / Ammonia as close to 0 as I can maintain
It is a 75 gallon mixed tank. Running Bubble Magus Curve 5 Skimmer w/ CO2 scrubber, 200 micron filter sock, standard black filter, 2 chemi pure elite bags rated for 50 gal per and a few brightwell bio blocks. Tank has been set up for ~ 6 months 'ish.
Thanks in advance.
