But as stony corals grow, and likely more are added, there comes a point where WCs aren't enough and there will be a decline in Cal, Alk and Mag. Without testing, the only way to know is when the corals stop growing and start looking sickly. This is not a good place to be. If you have just a few stony corals, and don't want o spring for the test kits, at least have your local LFS check your water every once in a while to see if WCs are keeping Cal, Alk and Mag in the proper ranges. Did you test when you where just relying on water changes? Quote Link to comment
