Shane,
Do you run your skimmer 24/7? I was having low nutrient issues after I added my 100g frag tank and switching out a sump. Instead of over feeding and leaving myself open to other problems from that, I just put my skimmer on a 10hr schedule 8am-6pm and have a 2 canister CO2 scrubber connected for that timeframe to help with ph. Especially in the morning. It allows me to feed my normal amount of my self made fish and coral gumbo and keeps my pH a bit higher for consumption/growth without bottoming my nutrients. I’m sure the time frame could be fine tuned for each reefers needs. If I get too low on PO4, I will feed a good amount of Reef Roids. If my NO3 gets too low, I’ll dose a bit of the Brightwell Neonitro that you use. Most of the time I am right in my desired sweet spot of .06/20
My ‘no scrubber’ pH range is 7.75 - 7.9. With the scrubber it averages 7.95-8.4. I am no expert on ph but I’ve been told that corals need the ups and downs of ph like we see over night for respiration/skeleton building purposes.
I also wanted to mention that when you dose nitrate, it will drop your PO4. I suggest that anyone dosing either should always test both together and then dose accordingly. These are just my anecdotal observations in my SPS keeping.
