 ## 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.
+Algae feeds on the nutrients in the water. One gauge counts them: the water adds 20 an hour, every fish adds 1 an hour (eggs count too) and every meal adds 3 at once. When the gauge reaches 100, the glass turns green. Open Water and equipment to see every source and every helper on its own row.
 
 ## 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. A filter adds to that on top of the cap: a better filter keeps the glass clear for longer, up to twice as long, but it never cleans it for you.
+Plants and decorations take nutrients out: each point of care removes 6.25 an hour, up to 18.75 an hour from all of them together, so the best planting keeps an aquarium clear about 4 times longer. Each item in the [decorations catalogue](https://fishies.lol/wiki/decorations) shows how long it holds algae off on its own. A filter takes out more: 3 for a sponge filter, 6 for a power filter, 8 for a canister filter, and 4 more from the refugium chamber inside the canister. Enough helpers can hold the gauge level for good.
 
-## Busy aquariums get dirty sooner
+## What fills the gauge
 
-The more fish you keep, the faster the glass clouds over. Eggs count too.
+A busy aquarium fills it faster. Three things push it up:
 
-- 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.
+- The water itself: 20 an hour, always.
+- Each fish or egg in the aquarium (a fish that has died stays until you net it): 1 an hour.
+- Each meal, from your hand or a feeder: 3 at once.
 
 ## 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.
+A grown, fed [Bristlenose Pleco](https://fishies.lol/wiki/species/bristlenose-pleco) is a helper too: it takes 5 nutrients an hour out of the water. It never scrubs the glass for you and never earns the wipe 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 few coins and experience, while scrubbing glass that's already clear pays nothing. The experience grows with your level, with the size of the glass (an enlarged aquarium's glass pays double) and with how green the glass had got.
+Choose Clean and scrub with the sponge whenever you like; there is no waiting. A wipe harvests the algae that has built up: it empties the gauge and gathers scrapings, coins and experience in proportion to how full it was, and a glass under 10% has nothing worth wiping. Coins and experience grow with your level, like a quest's reward, and with the size of the glass (an enlarged aquarium's glass pays double). Leave a full gauge alone and the glass greens over and the fish suffer.
