  2. IMO they overcomplicate. 

    In order of importance. Temperature, Dissolved Oxygen, Alkalinity, Salinity, PAR, Calcium, Phosphate, Nitrogen, and Magnesium are the only things you need to worry about. Not all can be monitored in real time, but IMO there arent reliable ways of measuring or taking action on nearly anything else. I think ICP might be OK for presence/absence, but I dont think there is consensus among experts in that analytical field that believe ICP-OES is accurate enough to make decisions on for trending. Just my unsolicited 2 cents. 

  3. Be very wary of ICP. It's a tool being used outside of it's intended use-case. ESPECIALLY the one you are using, its being operated by an entity that to my knowledge does not have a chemistry background. 

    Tin can be found in fresh PVC that hasn't had time to leach out plasticizers. Some new glass panels are also capable of having tin leech. 

    As for aluminum, what kind of PO4 remover are you using? Some are Al-based....

  4. Do you notice microalgae issues on new rock vs old rock? My theory is that you have old rock saturated with PO4 that is slowly being released into the water. Your fuge is very effective at removing both, but in the absence of macro the PO4 is released. 

    Maybe take it offline, run some form of GFO for a while to see if you can pull the PO4 out of the old rock over time, and then slowly ramp the fuge back up by limiting the photoperiod until you can achieve the nutrient balance youre after.
