Fish purchase
I bought Ram cichlids el. blue, Siamese algae eaters, Bronze corydoras and Serpae tetras. The plants grow very fast and some of them bloomed.

NO3 low... Easy Life or Seachem?
Thanks to the new light the plants grow fast. In May, I started observing deformation of some plants’ leaves. NO3 was low. Comparison of the Seachem and Easy Life fertilizers.

First prototype
The AquaSky unit development meant for me learning a lot of new stuff. I started this journey roughly a year ago. Now it is time to share my experience of the first prototype's test.

New LED light
The LED light worked on the aquarium for two years. The light intensity weakened and the epoxy coating turned yellow. I decided to change the LEDs. For the new light I used the white LEDs with CRI 98 and RGB LEDs which I placed inside the profiles with diffusers.
