So I have a few questions I have had my tank for about a year and a half and am finally making the jump to add corals. What are the added parameters I need to worry about and what are the ranges (Calcium and what should it read etc) I have put up 500 watt MH and found a killer deal on some dry live rock (.50cents a pound I am going to get 200 additional pounds yes that is not a typo .50 cents craigslist) My question is how do I need to wait to add corals to these new pieces if so how long? I can add it to my existing rock anyway. I also am going to need to pickup a new test kit with calcium since mine only has the basics trates, trites, ph, amonia, etc... What is a decent brand that I am not going to break the bank with, yet still be happy? Sorry so long thanks in advance for the input
