Probably true, I'm not really sure if daphnia nibble on the shells or if it
just dissolves into the water.

Calcium readings are unknown. I primarily measure the levels when I remember
to or feel like it. But I suppose they're probably high enough, given the
amount of calcium buildup we get in our pipes and the flecks of calcium that
clog up the faucet screen filters. My goal is primary to increase the number
of daphnia in the pond.
Last year I had a 2L bottle with it's top cut off. I used to keep it sunk
with a rock, and covered with a plastic grate. Periodically I'd inspect the
contents of the bottle to see what kind of aquatic insects are roaming
about. This year, I'm not finding much. A few 3mm long worms, which I
suspect are leaches are often anchored to the pvc pipes. A few dragonfly
nymph and I think I saw a ferry shrimp or two.
No luck in finding daphnia or planaria.
Maybe I'll find them as summer approaches.
