Mushrooms Revisited

I did some experimenting with putting granulated sulfur in a bag in the
sump. I also continued doing the lime drip. I found that the sulfur did
a great job of raising both the calcium levels, and the alkalinity levels.

It also did a great job of keeping the corals from taking the calcium
out of the water. :-)

Huh? Why would sulfur increase Ca levels? I've heard of Nitrate
reactors running the effluent through Ca material to reduce acidity
which would release some Ca. I think that was because of a high load of
CO2 and HS.
