+# Algae & cleaning
+
+_Why the glass gets cloudy, and what slows it down._
+
+## How algae builds up
+
+In a bare aquarium, algae starts to grow 4 hours after the last clean, and the glass gets gradually dirtier until you look after it.
+
+## Plants and decorations buy time
+
+Every plant and decoration pushes that moment back a little, and plants do the most. The total is capped at 4 times the usual time, so decorations never make cleaning unnecessary. Each item in the [decorations catalogue](https://fishies.lol/wiki/decorations) shows how long it keeps algae away on its own.
+
+## Busy aquariums get dirty sooner
+
+The more fish you keep, the faster the glass clouds over. Eggs count too.
+
+- 6 fish or more: the glass stays clear for 85% of the usual time.
+- 12 fish or more: 70% of the usual time.
+- 18 fish or more: 60% of the usual time.
+
+## A fish that grazes the glass
+
+A grown, fed [Bristlenose Pleco](https://fishies.lol/wiki/species/Bristlenose_Pleco) grazes the glass, so algae builds up 1.5 times more slowly. It never scrubs the glass for you and never earns the cleaning reward, and a hungry pleco stops grazing until it's fed. Each aquarium can keep one.
+
+## Scrubbing the glass
+
+Choose Clean and scrub with the sponge. Cleaning glass that has had time to get dirty pays a small reward, while scrubbing glass that's already clear pays nothing.
