Well I thought I had all this TFP stuff figured out, but I am currently 6 days post SLAM and found several areas with green algae on the wall in the deep end .
Obviously I need to SLAM again, but I'm not sure what happened. I have been checking my levels every day or two and FC has never dropped below 4.5. My CYA is 40 so that means my minimum FC is 3. Also my pump has been running 24/7 since the last SLAM because I haven't gotten around to re-attaching the on/off things to my timer.
What did I do wrong?
