A Little Chemistry

I changed 10 gallons of water yesterday (about 33% of the water in the tank) and the chemistry is looking pretty good. It has taken me 3 weeks but I got my SG up from 1.024 to 1.026. I am still working on raising Alkalinity and Calcium using SeaChem Reef Builder and SeaChem Reef Advance Calcium. Once I get the numbers where I want them I bought a two part system: SeaChem Reef Fusion 1 and 2 to maintain these parameters.

• Temp: 78
• SG: 1.026
• Ph:8.2
• Ammonia: 0.0 ppm
• Nitrite: 0.0 ppm
• Nitrate: <5 ppm (close to 0)
• Phosphate: 0.0 ppm
• Calcium: 400 ppm
• Alkalinity: 9 dKH
• Magnesium: 1290ppm
• Iodine: 0.06 mg/L

I bought a SeaChem Iodine test and it's really a tough test to judge because the color is not that stable, so I have very little confidence in it. I order a $40 professional test kit to see how that compares to mine. Although I sent test out last week, so their numbers will be from last Monday and these numbers are from my test last night (Sunday) after my water change. I took a test last Sunday, so my plan is to compare it to that one.
