There is no way around water testing. If you're going to be a successful reefkeeper, you may as well get into the habit of testing now. Recording your test results will help you see where you are in the curing process.
When ammonia and nitrite levels are at 0 ppm, the rock will be cured. This process can take up to six weeks. DO NOT add fish until test results confirm that the rock is cured.
