It appears that my GH is a smidge high and my KH is a smidge low. In using the API test kit, it took 2 drops to change color for KH (so 2° dKH, right?) and 8 drops for GH, which the chart says is equivalent to 143 ppm.
I have plants, angels, and tetras (as well as cories, pictus, ropefish, rams, and a betta and gouramis), so it says I need 3° - 6° (50 - 100ppm). I'm off on both. What would be a good way to get my hardness where I need it?
If I'm reading things wrong, please correct me. This is the first time I've ever used a hardness test kit.
Also, my pH is low. I'd fixed that and had it perfect by adding a bag of coral in my HOB, but I removed the HOB in favor of a few sponge filters. I added dragon stone, but apparently not nearly enough? How much stone would I need? Are there other pH raising options that aren't chemicals and don't require HOB/bulky filters?
