Hello!
Here is 4 days of growth, one with flash and one without as usual.
The picture I posted from the previous cleaning was from 7 days of growth, seems almost the algae had more green color ettter 7 days growth than those with four days growth? Why?:
When it comes Steni material I have used as a screen the algae sits very firmly in the screen. I have to work very hard with this brush to get rid of the algae, and after a good scrape there is always a good amount of algae left in the rough surface. I think this matrialet is very well suited to screen for those who will have a one-sided scrubber.
