It was recommended that I post this here to get some insight and hopefully a recommendation. The issue I am having is a blue/green cyano outbreak. It has been going on for about 6 weeks or more at this point. My nitrates and phosphates are both reading 0, api for phosphate and salifert for phosphates. I have a 10% WCs routine which has been altered with 20% the last 2 weeks in an attempt to manually remove and lessen the nutrients available to it. There is a lot more info about my situation in my original post here, but if you need specific information and don't want to read through the entire forum, I understand and will post any information here you would need. Thank you.
