First ICP Test Results - Any Advice?

[AKay3600]

Hey, just got back my first ICP test results. Not 100% sure how to read the results but looks like like some of my numbers are coming back lower than I thought, salinity and alk mainly. Any advice on how to proceed? Have had the tank running for about 7 years now but went through a move and upgrade in January. Overall running pretty good just not getting much growth it seems and have always struggled at keeping zoas for some reason. Thanks!

Looks good to me.

I'd raise the salinity a bit and consider adding a trace element supplement for ions such as iron and manganese, if you do not already. :)

Phosphate/phosphorus showing down, make sure it does not bottom out, or corals, micro-fauna and bacteria starve.

Thanks! Yeah may look into a different method for checking salinity and get a different type of Alk test. I've been using All For Reef and Aminos but will look into something to bump up those trace elements.

Yeah that I have also been working on for the last month. I have started dosing nitrates and phosphate in the last 2 weeks and have been trying to up the feedings. I have been thinking that my main issue with coral growth was my lack of nutrients and this seems to show that as well. Thanks!
