Keeping my hands out of the tank isn't a problem. I loath the dry skin that comes after having my hands in the tank. I can definitely stick with the no hands in the tank policy.
I'll keep working with the Mg, at the rate I'm going it will probably take until the end of the month to get it up where I want it.
Can you tell me more about precipitation? I thought precipitation was always white. I don't see any white though. Can precipitation not be white? I'm going to go google precipitation, but I figure that you would probably know

My kalk. reactor has actually been offline since the 11th. I just realized I never put it back offline once I reloaded the kalk. powder, oops! I'll take the Ca. reactor offline too. How would I go about figuring out my daily usage? Would I just measure the parameters every day and then average out the differences?
Just because I'm curious; if my reactors are dialed in properly, and I am seeing a consistent set of numbers for Ca and dKH without precipitation wouldn't that mean that I'm meeting the daily usage? Does that even make sense? I think I'm confusing myself
So here I guess is my plan for the next while, tell me if I've got something wrong;
- Return my water changes to 1x7g/week. For clairification, the 2x7g/week water change was when I combatting the GHA.
- Continue to raise my Mg. Should I still do this while I'm trying to calculate daily usage on Ca, and Alk.?
- Take reactors offline
- Measure daily consumption of Ca, alk, and mg?
