Good day all, and happy friday. @Randy Holmes-Farley could you help me understand the need to dose phosphorus? I received my latest icp test Link, per this evaluation i am low on Phosphorus and nitrate. I have started dosing ATI's nitrogen solution but am curious about dosing phosphorus. Is there a difference between Phosphorus and Phosphate? Should i dose it? I understand phosphate is a good thing at very low levels, and is easily available from most fish food or other additives. I only ask because the test also indicated im deficient in iodine, after dosing per the recommendation i had green slime algae within a week . Any clarification would be appreciated.
