A few leaves on my Amazon Swords have a black film of algae. What are the causes and solutions? Its a 10 gallon tank, 3 watts/gallon,fertilizer tablets are added and lights are on for 10-12 hours per day

Thanks Justin

Hi Justin,

There could be several reasons for an algae outbreak, from poor water quality, to over fertilizing, to excess lighting, overstocking, over feeding, etc.

How often you add the fert tabs? How long do you leave yoour tank lights on, and how often do you do water changes?

What you can do as an imediate messure is to remove the afected leaves, and do a 50% water change.

It also depends on what kind of algae we are talking about, but you can check the folowing link to see if there is the one you got.
