Zoone

I made a quick check today, NO3 and PO4 was about the values that i expected, 10 and 1.5.
Fe was quite a bit lower than i wanted to 0.05 – 0.1, when i would like it to be roughly 0.2, so i had to adjust the dayly dosing of Fe / micro.

All algae are not ugly and boring to have, this is some pictures i took this evening of some algae that are decorative.
