Update:
Since I added phytoplankton and copepods it looks like the color got better, more intense. Today I dipped her, as I got into temptation to buy another one and didn't want a bacterial infection also get into a new torch.
One minute after dipping, as I can finally do pictures of the base. I dipped AquaForest Protect Dip for 5minutes, then rinsed and put it back to it's former place. There is some white stuff, I tried to blast it off, but I can't. Anybody got some tips? In my unexperiences eye it looks like it is some sort of illness?
