I everyone, I was doing some water test and found my kh was at 1 it has always been at 3 and know comes out of the tap at 1. With my ph at 6.6-6.9 I will not be getting much co2 in the tank for the plants. This is a 90 gallon tank will I have to add a lot of baking soda too get this up? any suggestions ? thanks Ed

Re: ??
I don't think the low KH will prevent you from adding as much CO2 as you want, but it will lead to the PH dropping much too low if you do. Why not just add a couple of teaspoons of sodium bicarbonate (baking soda) to raise the KH a degree or two? It might take more than two tsp to do it, but start low, wait a day, add more as needed. Then, when you do a 50% water change each week, just add about half of what it took this time along with the water.
