Thanks. I do test mag/alk/calc every four days and have BRS 2 part on hand when I need to dose. The only thing I've had to dose is alk. After four days my test shows around 8.24 so I dose back to 9. One of my next purchases will be a Hanna checker so I can test alk more accurately. Once I'm certain of the numbers, I'll start dosing daily.I agree with Anthony your tank is very new and not all that stable just yet, adding a bit stonger light to the fuge wont hurt you, but I wouldnt worry too much about chasing these level just yet, just perform regular water changes and monitor the levels for now, Most importantly keep your Alk stable, constant fluctuations of Alk is generally the cause or coral problems aside from pests.
