My KH GH and PH used to be low at ~1-2, 1-2 and 6.4-6.6..
recently I learned to increase KH GH with NaHCO3 (kh) and CaCl2.2H2O + MgSO4.7H2O (gh)
I added this as necessary in two wc cycles and now my parameters are as below:
overall I feel better plants (more pearling, greenery, new green leaves) which I think must be due to better GH (more calcium I believe, I am not sure).. But I do see some new brown dust also (brown dust algae? I don't know)
can above be considered good numbers ?
Is that not high pH at 8 ?
If that is high pH should I lower that a little with some WC ?
I got worried of this some new brown dust..
Please let me know. .

I checked my tap water and i am surprised my tap water itself is PH around 8 !!!! This was never so.. It used to be 6.4-6.6.. I have no idea how my tap water itself has become ph8 !
