I have a little ten gal tank with 2 cons. I been just changing the water and cleaning the filter. 4 days ago the tank was Consumed by alge. i wasnt able to see inside the tank. So i thought i might wipe down the front tank. Did this... and today 3days from when i wiped it down.... ALL the alge is gone. all the walls and rocks and all... even out of the filter... now what happen? i just now added a plant like 1hr ago... didnt bother to see if the alge was all gone. Thanks.
