- It's probably written down somewhere, but I don't have it here. However,
- I believe my solution to be stronger than is optimal. Since calcium
- hydroxide almost works, I suspect that the way to determine a good
- concentration would be to mix up a solution of sodium hydroxide with a
- hydroxyl concentration that is a bit higher than that of saturated calcium
- hydroxide, and then slowly increase the concentration until you get
- reliable kills. It might not take that much more. I don't know for sure
- if similar hydroxyl concentrations have similar lethality, but this seems
- like a reasonable ballpark estimate. You could also match pH's instead,
- which would probably give you a similar initial concentration.
-
- I ought to do this experiment, but I don't have many Aptasia left. I
- guess I could leave them alone for a while until I have enough "volunteer"
- test polyps.
-
- Again, don't go doing this without knowing what you are doing.
