What else will slow down algae?

I haven't been checking and I top up with kalk.
It's just run away i assume. I'll let the top up run with plain RO water for a few days and let it drop a bit.
But the test kit could be wrong.

Try doing 10% water change for a week and make sure to suck most of the algae, and 48 hours without light then 3 hours only with light after, for the rest of the week.
Just my thoughts, this method works for me when i had the dino..

using kalk can be really harmful if you overdose it.
how's the skimmer looks like??maybe it is not working hard enough??
