sooo I have a water box cube 20, and am looking for some guidance. I have a bit of an issue with elevated phosphates. My recent results show a phosphorous of .41 ppm (.12ppm phosphate converted) and nitrates at 0. Currently have a small skimmer that I have now turned off for 12 hours to hopefully increase the nitrates a bit, I purchased phos fx, but I’m lost as to how much to introduce to reduce the phosphates. Outside of doing weekly water changes, is there anything I should be doing that I’m currently not doing? Should I use the phos fx? And how much should I use from the bag (250 ml bag size)? Thanks in advance for your assistance. For reference I’m currently using phytoplankton daily, reefroids sparingly weekly, and stopped pellets for my clowns and gone with only mysis for fish feed.
