Strontium testing

Trying to decide if I should be testing for strontium and dosing.  My tank has been up since beginning of March and my corals are growing very well.  I do add Kent's Marine trace minerals every other week and I dose with Seachem calcium and reef builder alkalinity.  I plan on using bulk reef supplies bulk additives when my seachem is gone.

Alk and Ca testing
In my opinion Mg testing is next and is more useful than Sr testing. If a hobbyist feels that Sr needs testing, then they might also want to test Iodine, PO4, Fe.... it's not commonly discussed but Sulfates are over 7% of natural seawater composition. Compare that to Mg compounds at just under 4%.

I find this enlightening: http://seagrant.gso.uri.edu/G_Bay/HabitatEco/Ecosystem/sea_water.html

Don't be fooled by the statement we often hear that the ocean reefs are nutrient barren. The abundance of organisms on the reef are eating nutrients faster than testing can detect them in the water.

Good live or fresh frozen foods contain the trace minerals/nutrients that the reef needs. It may seem gross to some, but we understand that fish waste is nutritious food containing much of the above mentioned nutrients.

Just thought someone reading this might want to know.

AC all the way

I say do it. It's just one more test.
Your test results with Iron are curious and you may be right. Macroalgae grows much better when Fe is present.
Don't know the answer to that one.
