Long story short I mistreated my AIO 50G tank for a little over 2 months causing nutrients to rise and algae to take over , Iv been carbon dosing Elimi-NP for about 2 1/2 months now plus the help of Vibrant to clean out my algea, I have reach near my desired levels and been stable at 5ppm No3 0.07 Po4 , and a point where little to no algae left , I would like to incorporate a HOB refugium in the next coming weeks to let my Vibrant bacteria fade away and discontinue the use of carbon dosing. (I had given a cheato reactor a try prior but my algea in my dp had outcompeted my cheato) My fear is zeroing out my nutrient while making the switch or the total opposite. Any tips or tricks on how to transition safely ?
