The sun is still shining!

13/9/2017

It's been a month since I discovered some baby sun polyps in my tank. There are five that I am aware of, all are still present and correct and appear to be getting a tiny bit bigger. I am not feeding them directly so they must be catching whatever fish food or plankton that happens to pass by.

One step closer

Time for another ICP analysis to see how things stand with the Tin pollution as of 29th August 2017.

I'm pretty happy with those results, just a tiny bit more tweaking required and everything will be right where I want it to be. The Tin has finally fallen to an acceptable level and hopefully will continue to fall until it's undetectable. The Calcium dosage needs increasing and the iodine dosage reduced a touch. One lesson learnt here is that the test kit used to monitor the iodine levels in between ICP tests (Salifert) is a complete waste of time. The iodine level in the tank has gone from 0 (mid April) to 74ug/l (end of August) and in all that time the test has registered nothing more than the faintest hint of colour which equates to less than 0.01ppm (10ug/l). I knew before I started that the home test kits for iodine were considered inaccurate but I didn't realise they were quite that useless (well the Salifert test anyway). I won't bother to use it again.

I'll sign off with an updated FTS (as of today) this time featuring a beautiful splash of yellow. My Halichoeres chrysus wrasse is pretty hard to miss don't you think. When I introduced her I had assumed that she was actually a he but I have been informed that these wrasses are all born female. So she now goes by the name of Rei instead of Ray and she will remain female for a while yet before making the changing to male on adulthood.
