Yep, it takes up a lot of calcium. When it dies, it will
be white as the sand.

Well I might have thought so if the RO water wasn't testing 0 and a
petshop didn't get the same result. One day I will get round to testing
the tap water (straight from the creek). By the time I test all my tanks
(FW as well) I get sick of testing. My nearest marine pet shops are all
2 1/2 hour's drive away in 3 different directions

I've tested and tested. There is meant to be a colour change from pink
to blue. Mine only changes to dark purple at 600 really. I can get to
higher if I try to go for the exact shade of blue and that is in front
of a window with good light. At 580 the sample is still bright pink.

One thing though. I have some sort of algae or seaweed thing gowing
well. Not overtaking but it's looking quite good. It's bright green and
sort of cactus shaped, like a zygocactus but it is hard. I'm wondering
if it would need Ca to thrive and maybe that is why it is thriving. The
tang doesn't touch it as far as I can tell. Visitors love it and think
it is planned - I don't enlighten them

Is it possible it is a test error or test kit issue ?
