2Hr Aquarist APT FIXLITE 100ml

Regularly change water the 2Hr Way and remove old/ decaying leaves.
Stem plants require replanting of the healthy tops after trimming once or twice. Old deteriorating stems invite algae to bloom.

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.
Both APT Fix and APT FIXLITE use active compounds that biodegrade naturally over 12- 24hours, with no nasty residues.
