I indeed have a very strong light... On my other tank i had the problem the light was not strong enough, so i though this time i will buy a strong one. But this one is way to strong... the shop told me it would be fine if i had a black water setup... I added some tannings and did start with the blackout today. I did simphon of most of the blue algae before this, but with only little water. Will keep the water changes small if it's not gone after the blackout and add more tannings. I also decreased the light hours a bit to 7,5 hours now.
