Follow the SLAM process, followed by the Mustard Algae protocol.
Thank you, I did.
Though I didn't do this... "If you have underwater lights, they should be removed from their niche and the niche brushed out, and then the lights replaced."
My understanding was FC @ 2-3 ppm was the right level.
Could you please tell me what it should be?
Edit. Looks like I misread this chart. I guess 3-5 is the correct level?
