I did a water change (about 20%) and took care of the bad stuff and tested my water today.

Here are the latest parms:
Ammonia 0.0 ppm
Nitrite 0.0 ppm
Nitrate 5 ppm
Alk 2.86 meg/L
Calcium 380 ppm
Phosphate .03 ppm
Temp 80.5
Ph 8.0
SG 1.025

Now my question is this, I thnk my Calcium level is a little low what is the best way to bring this level up and maintain it. Also the phosphate level, is that ok? I would expect it to be like zero but I did get a little reading.

Any sugginstions are welcome.

Thanks
