Hello:
I am new to reefing and have an Innovative Marine Fusion Nano 20 gal tank with skimmer and carbon reactor. It's been going for a couple of months. The tank has a lot of LPS, softies, and 9 small fish.
Question:
My readings are as follows:
- NO3: 0
- Ammonia: 0
- Alkalinity: 12.3 to 13.2 (depending on which test kit)
- Magnesium: 1400
- Calcium: 470+
I do about a 20% water change each week and my readings are always high, as you can see above. Is this cause for concern?
- When I add fresh water it is RO water.
- The salt water I get from the LFS.
Are there ways to reduce these numbers besides adding RO water (already doing) and more water changes (already do every week).
Much appreciated!
