Reef Network Dinner - May 20

[Snaz]

I'll be there. I was wondering if I could bring a sample of my water and have one of the Pros take it home for Ca, Mg and Alk testing please. I currently only test for pH, ammonia, Nitrite and Nitrate and I was hoping to get a better idea of where I stand in regards to the needed trace elements.

My favourite patch of Zoas has been shrinking slowly over the last 3 months. Everything else seems to be thriving though but I want to rule out my trace elements. I do 10% weekly water changes every Friday so Wednesday would be a good day to test and see if I am depleting something before I do a water change.
