Hi all, I have hard water (at least 300 ppm according to the Tetra test strip). Unfortunately I don’t know what makes up the hardness. I checked the board of water supply’s water report but it didn’t mention either component. I’ve found saltwater tests for calcium and magnesium but not freshwater. Anyone know of any testing mechanism for these two components, or does it matter?
I've been studying a chart that shows plant deficiencies and what nutrients the plant is lacking and according to this chart I need magnesium. I've seen online that one can use empson salt. Has anyone used this and how much per gallon. Also I've got an api calcium test kit but it's hard to follow cause the colors are very faint. Nothing like what I've seen on YouTube. I. pretty sure I'm also missing that and I've read you can add crushed egg shells. Anyone tried this and does it work? I've got well water but we run a water softener. I know our water is still heavy on iron from the constant cleaning of our sinks and tubes. I'm assuming that's what it is. I tested my GH,KH and Calcium and heres the results. GH was 3 drops 50ppm, KH 22 drops which was through the roof at 400ppm and Calcium was like 2 drops at 60ppm. My Nitrates have significantly dropped since adding the pothos going from 80 to 100ppm to 60ppm which is huge win in my book
