2Hr Aquarist APT Fix

The best natural defence against algae is a healthy dominant plant mass. 70% of a tank’s substrate should be planted.

Tanks with large exposed, un-planted areas are far more susceptible to algae, in the same way that fertile open fields invite weeds to grow.  The problem is that copper, like other heavy metals, accumulate over time and do long term damage to the tank’s ecosystem.
