Hello,
From tap pH is 7.5, KH 1.5-2 and GH is 2.5-3.
Tank pH sways between 6.4-6.8 depending if CO2 is on or not.
Substrate is ADA aquasoil + I have driftwood.
The odd part is that for some reason KH and GH in the tank have risen up. KH is 3 and GH 6.
Temperature is at 24.5 celsius.
CO2 injected in the tank for the same time as lights are on (with 1,5h offset). CO2 was a bit high a week ago (lime-green/yellow'ish drop checker) but tuned it down (green drop checker).
I dose according to the estimative index daily, using an auto dosing pump. It pumps a total of 10ml of Aqua Rebell Makro Basic EI in 3 smaller doses along the day. https://www.aquasabi.com/Aqua-Rebell-Makro-Basic-Estimative-Index
I also dose traces, for which I use Aqua Rebell Mikro Basic Eisen and dose a total of 2ml per day in two doses of 1ml. https://www.aquasabi.com/Aqua-Rebell-Mikro-Basic-Eisen-500-ml
Together these add the following nutrients in the following amounts (daily):
3.07 mg/liter NO3
0.57 mg/liter PO4
2.34 mg/liter K
0.15 mg/liter Mg
0.017 mg/liter Fe
0.008 mg/liter Mn
0.001 mg/liter Cu
0.00067 mg/liter Bo
0.0003 mg/liter Zn
0.00067 mg/liter Mo
Any idea what might cause this? From what I've read I should be detecting KH going down, not up. And I don't know why GH would be going up. I do 30-50% water changes weekly, and just did one yesterday.
