OK 2 weeks ago I had Flourite/sand in my tank. Before I pulled it out of the tank my test results were
gh off the chart..it took 26 drops to change the color!
I've done 2 water changes since I pulled the Flourite out and put in Volcanic and Flora Base, here are the new results
kh 3 drops = 53.7ppm
gh 4 drops = 71.6
Nothing else changed except the Flourite came out of the tank. I did the tests at least 4 times each with 2 differant liquid tests. Oh, in case you wondering, my tap water is
kh 6 drops
gh 4 drops
