Softening water without hurting plants
I have 14 Celestial Pearl Danios in a 15-gallon bowfront tank. CPD prefer soft water, so I tested the hardness today, and it was really hard. My tap water was 9 drops on the API GH test, my 55-gallon aquarium was 9, my 29-gallon was 15, and my little CPD tank was 16! I have no idea why the smaller 2 tanks are harder than the others. I have some seashells in the 29 gallon, but nothing that might harden the water in the 15-gallon.
I thought about buying a water softening pillow, but I am concerned about the plants in there. At my previous house, I had a water softening system that kept the hardness basically at 0, and my plants didn't fare well.
If I buy a water softening pillow and use root tabs and Seachem Flourish liquid fertilizer, will both my CPDs and my planted and floating plants be satisfied?
PS: Plants are Anubias nana, Red Myrio, and Water Sprite.
