too much light?

Agreed. When you get your water to NSW levels, you'll probably see the algae
blooms decrease substantially.

I checked my notes
PH 8,25
KH 9,6 dKH
Ca 400ppm
Mg 900ppm
I've just recently bought tests, and Ca was low. Dosing kalkwasser
boosted it from 300 to 400.

Algae
1) bloom - mainly on bare bottom and glass - a layer fast growing,
brown, slippery, with bubbles, on bottom it makes a sheets sometimes
flowing around. A snail seems to eat it (from glass).
2) coraline - how long will it take to see any grow after having good
parameters in tank?

It's latest picture from my tank

What's that animal? It constantly "grab" water searching for plankton.
You can see algae there too.
