I'm setting up an aquaponics system and I'm wondering whether or not a protein skimmer will take out ammonia from the system I need nitrates and nitrites to still be in my system to fertilize my plants and for the nutrients but I don't want the ammonia in the system and I need a little bit of filtration to take out solids but not enough filtration to take out all of the bad stuff that the fish don't like I need that stuff for the plants so will my protein skimmer take out all of that good stuff that I need for my plants or will it only take out the solids and ammonia?
