So my tank seems to have passed the first coral test, all of the frags I introduced 12 days ago are still alive. Phew! The Stylophora is even showing signs of growth. I think it might be time to add a few more at the weekend and maybe even another fish.
The coralline has really started to take off, I'm seeing spots of growth on the pumps and on the back wall too. I am undecided as to whether I should scrape it off for a nice clean look or leave it au naturel. I'll live with it for a while and see how I feel when the coverage increases. Spirorbid worms have also begun to appear in the DT and in the sump too.
The tank parameters as of this morning are:
Specific Gravity 1.026 d SG
Alkalinity 6.85 dKH
Calcium 425 ppm
Magnesium 1270 ppm
Nitrate 0 ppm
Phosphate 0 ppm
I'd like to tweek the KH and Mg up a bit more but those values are not too bad. I am extremely surprised not to have any detectable NO3 or PO4, this is a bit of quandary for me, I don't think I've ever had a tank with no (or low amounts) of NO3/PO4. I guess the Siporax and refugium must doing their thing, it is early days though and stocking is light I so expect that the levels will rise soon. I do have a bit of furry algae growth on the rocks and a film of algae forms on the glass so I know that there must be some nutrients hidden in there even if the tests say different.
