Winter: pH 8.29/7.9
Spring: pH 8.01/7.67
Nothing changes as far as windows, stay closed all year winter or summer. No insulation changes, heater is electric heat pump, AC is electric (all same unit). When my AC has been running it seems my pH drops overall.
I also could have gotten some beneficial bacteria strand that's eating pH too as my nitrates are very low (usually keep them around 10 but they have been steady at <1 lately). When I had ultra low nutrient tanks I ALWAYS noticed my pH would run way lower than without.
Anyone know where I should look? I don't want my pH dropping to 7.5 like it did last year!
