Now, there are several shades of blue. First it changes to a dark blue then to a much lighter blue. If i measure to the much lighter blue I get much higher than 450, much closer to 500.
Which blue?????
As for what I'm doing, well it's a long story. The short story is nothing!
I was testing before today with a REd Sea test kit and it showed 500 for about three weeks. Even after a water change and adding a bunch of soft corals. i thought that it would diminsh after a while, but no change. Bang Guy told me that i needed a new test kit...a good one...so I got one. I'm getting alot of bright green growth on my rock and all my softies look good. I was about to set up a automatic topoff/doser to get it up if I needed too. But I guess I don't need to do that. I have to check for ALK though. How does good calcium affect ALK? And how is it that I'm maintaining constant calcium readings?
This is all so confusing right now...please explain!
