Thanks for the advice. I’ve been thinking about the NO3 and PO4 relationship more. Got me thinking about sources. Which went to feeding. So I started to think about how to effectively manipulate both with feeding. Please let me know if this makes sense. Eaten food turns into NO3. Uneaten food dissolved into the water column and will increase PO4. Use lots of sinking pellets whereby a good % hit the sand bed uneaten. This is for PO4. Then feed the fish until fat with mysis/frozen choices, flake, whatever they will readily eat. This will increase NO3. Use Nori for a combo of both (eaten and dissolved). Also since being gone for 5 days and noticing no change in my 0 PO4, I’ve turned off the skimmer for the night after a feeding matching as I’ve just described. It now sinks in (I think) that my corals need the nutrients sooner rather than later and my fish won’t react adversely. Therefore why not turn it off to jump start my nutrient accumulation. Thanks to anyone who can double check my thinking and tell me if I’m finally getting it or if I’m off base. I guess, ultimately however, only my results can confirm this. Here’s to hoping.
