We are considering to move the forum section to the Facebook page. Maintaining all forum spammers takes a lot of time and we currently only work with volunteers. We should not want everything that is not necessary, there is already enough to do.
The algae breeding unit
Algae grow in water.
They remove all kinds of substances from the water and thereby make the water cleaner.
The cleaner the water the easier we can make drinking water from it.
