That's my point. Feeding too much will not have immediate affect on your nitrate levels ( food and poop have to decay first before it turns into nitrates) and by the time it does your algae ( macro/ micro) will consume it right away leaving nothing for your corals to consume.I feel like I feed too much. Fish are fat
I would also control cheato / skimmer running time as it look like your export method are way more powerful that the intake.
