Nerite and Horned Nerite Snails eating algae - time-lapse

Nerite and Horned Nerite Snails eating algae off anubias plants. time-lapse. Recorded May 1, 2015. 60 gallon, low tech planted tank. After I removed all my pest ramshorn and bladder snails the algae started getting out of control. I added some nerite and horned nerite snails and they cleaned up the algae in just a few weeks! My aquarium needs snails.
