My KH is 5 drops (89) my pH goal is 7.0 and the chart tells me I should have between 15 & 24 ppm. If I want to keep my tank at 7.0 where should I put my SETPOINT? FYI, I have a high tek tank with 4 54w HO bulbs 216w or 2.88 wpg. 2 Giesemann Midday & 2 power chrome aqua flora 50/50 mix. Fixture is the current sundial.
