New to hobbie. 120 gal. reef. been cycling for about 5 weeks. Started with cured live rock and live sand. Experiencing algae die off. beautiful and expensive Fugi rock turning white. Picked up reef test kit and started adding calcium. Will this stave off the algae die off ? Also noticed that my carbonate level is high. around 11dkh. I took the carbonate reading after dosing with calcium. could this be the reason for the high reading ? Is a high carbonate reading bad? I am also in the market for equipment such as contorller, phosphate reactor, calicum generator with CO2, chiller, UV sterilizer. I still need to research sizing of above mentioned equipment..I have learned as an industrial tecnician that it doesn't make much sense to load up a $300 dollar motor with $ 1500 worth of protection. Does this logic apply to this hobbie with respect to tank size or is this more of a matter of maintaining a critical process. Is there a reliable cheaper source for chem. additives and test kits ?
