I believe it is a meter of extra CO2 and greater clearness of water, not because of extra O2.
I mean can pearling be visible if water is not saturate with O2?
I believe it can because when i ad en extra light over one 250 l tank ( usual it is lighten whit 120 w MH and i add 800w reflector for picturing it ) plants start pearling like crazy in two minutes.
Not enough time for plants to change saturation of water with O2

Well, I've been to Zagreb and most of what was Yugoslavia.
It was an nice place back then.
Hopefully things are getting better.
If you can read Slovaian, I had an article come out in that language recently.
You can type and speak better English than I could any of the languages spoken there. Do not feel bad about your English skills.
Try adding more CO2
slowly.
Add just a small amount more.
Then watch the aquarium.
Then if all looks well, add a small amount more CO2.
Watch the plants.
Watch the fish for signs of gasping for at the water's surface.
Reduce the CO2 if you see any probelms with the fish.
Make sure there is enough water surface movenment.
You can always add more CO2 for the plants, but the fish are more important.
Plants will pearl even if the water is
not saturated with O2(O2 at 100 % saturation). All they need is a peroid of good growth: light, CO2 and ample nutrients.
