Peat (sera super peat) against algae?
I simply doubled the peat granulate amount (sera super peat) after I encountered strong algae growth. Whatever the reason is, the algae problem stopped immediately. Peat somehow seems to be a wonder weapon.
peat is indeed active against algae, even in two different ways: Many algae grow better in alkaline water containing carbonate than in acidic water low in carbonates - and light filtration caused by the water tint is also rather effective! The only limitation: Peat filtration is not suitable for all fish, for instance it would be completely wrong in aquariums for East African cichlids!
