My 600lt Mixed Reef including 11 Carpet Nems and 30+ fishes, and 5 feedings per day, have always had issue with Phosphates... Approached Brian for a solution on these issues, and managed to control phosphates to 0.02-0.08 using the PCS phosphate remover. Over the past week, I had noticed my phosphates climbing and eventually hitting 0.18! Worked out that I was introducing 10.4ppm of phosphates through my food each day, and was suggested to test each food individually to determine the source of the issue !

Just wanted to share the results

Note-the quantity of food is what I use for each single feed.
