Definitely the best algae eater

The first photo shows how the wood looked like, the day I introduced the Neritina sp. Zebra snails, and the second photo is presenting you the result after just one week :-) These snails really are tremendous algae "cleaners"!
Of course, algae eaters aren't the solution in combating algae. Balanced fertilising regime is something one should focus on. Estimative Index fertilising method is one of the best solutions in growing lush and healthy plants = algae free aquarium.
Keeping a few algae eaters of course helps a bit, because all aquariums have algae. Some less other more ;-)
