[mattyice]

i would do both, dose kalk and water changes if you dont want to use any two part, in my 240G cube i am running a calcium reactor, a kalk reactor, dosing two part, and doing 1-3G water changes daily, but in my case i am going to use the Italian Blu Coral method so i will have extremely elevated levels of calcium, mag, alk and i need to over do everything
