Its crazy how some of these algae and bacteria work. After last deep clean I was pretty much dino free and could literally see the cpl patches that I missed dieing off. All it took is me to stop paying attention and let phosphates 0 out. Came back with a ferocious force and completely took over in just a day or 2. Good thing is I've solved the riddle. I beat myself this last go around lolI honest thought I would see dinos again but just some film algae my pods are loving it
