I add Calcium chloride to my tanks as my source of Ca. I do this because I bought it years and years ago before there were other easily available kinds of Ca. From reading on here, I figured out maybe I'm not adding enough, but I'm afraid if I add too much, I'll have too much Cl in my tank.
Anyone know when I start having to worry about this? From Wet's fertilizer calculator I need about 5 tsp in 75 gallons which gives 30.6ppm Cl.
