Ok week now and I just did my WC of 16G and dosed the recommended 1 ampuole of stronti.
Parameters today were:
SG 1.025 CA:475 Alk:10 Mag:1320 Nitrate:5 Phos:.02
Observations: Sandbed nice and clean and I havnt cleaned the viewing glass since last week! My skimmate is still black and chunky but the volume appears to be reduced. Filter bags are coming out black and I am changing them every 2 days. My water is probably the clearest I have ever seen, all bright and sparkly and no hint of yellow. In fact I noticed when I did my WC today that the buckets of old water looked as clean as the buckets of new water, usually they have that slight yellow colour.
My polyp extension is no where to be seen yet but who knows.
Here is a picture of a coral frag that I got from Marie. It doesnt show in the picture but It has developed a blue tip on the closest branch and the edge of the growth on the base has turned blue. Perhaps she can chime in as to wether hers has ever shown signs of blue tips?

This is the triclour 3 weeks ago and today.
This is the rose milli 3 weeks ago and today.
None of the colours have changed much on any of the corals yet
