My plants have been growing pretty slowly and not looking healthy and the water parameters are not ideal for my stocking so I've decided to spend some time trying to nail down my water parameters. My current parameters with the liquid test kits are GH of 30 ppm, KH 40 ppm, pH 7, and 0 for ammonia, nitrite, and nitrate with my tap water being almost identical. I am trying to target a pH of 7-7.4, GH around 150 ppm, and KH around 80 ppm. To try to get a little more insight on the chemistry I ran some ion chromatography on my tap water and tank water and am getting 12 ppm Na, 1.9 ppm K, 1.4 ppm Mg, 18 ppm Ca, 0.6 ppm F, 22.4 ppm Cl, and 17.6 ppm SO4. My tap water is nearly identical plus trace amounts of NO3 and PO4 that I guess my plants are using up. The only thing I am currently adding is Tetra AquaSafe+ with water changes, Flourish Excel daily, and Flourish once a week. Any recommendations for what I should be adding to get the ideal parameters and healthy plants?
