The above shows the result of a single dose of APT Fix via spot-dose method. By Day 2, the inactive BBA would usually change color to red and/or white. These would either decompose, or serve as food for algae-eaters and other microorganisms. By Day 7, the leaf is now mostly free of algae.
The above shows the result of a single dose of APT Fix via the drain-dose method. By Day 2, the hair-algae has lost some of its green color. By Day 5, all the hair algae has been deactivated. You can remove it completely using a fine brush.
Yes, but this approach is less effective than spot-dosing or drain-dosing.
APT Fix biodegrades naturally over 24 hours. So you can repeat the recommended dosage very 24 hours.
The most effective way to avoid new-tank algae problems is to properly cycle the tank before planting and introducing fish.
Inadequate Cycling often results in Diatoms ( brown fuzz on the edges of leaves or thin, brownish spider-web like strands) or Green Water ( which is triggered by excess organic waste).
While APT Fix will work against these forms of algae, it is better to simply have patience (in the case of Diatoms) or review the causes of Green Water as we describe in our guide below on the different types of algae.
Within the recommended dosage, no.
The exception? Plants that are already very weak.
Both algae and the plants will be similarly affected in such a case.
Also, exercise extra care when spot-doing on Mosses, Liverworts (Riccardia and Riccia etc.) and Vallisneria (Tape Grass) as their cell structures are much more similar to algae than other plants and are therefore more susceptible to being affected. We recommend spot-dosing rather than the drain-and-drip approach for these plants.
As a rule, old leaves do not recover as plants channel their energies towards new growth and naturally discard older stems and leaves. You can rid the older leaves of algae, and delay their deterioration, but the leaves will generally not regain coloration or sheen. For most aquatic plants, long term tank maintenance involves routine replanting of the healthy tops, and removing old stems and roots.
APT Fix does not harm healthy fish, shrimp and other livestock within its recommended dosage. Of course, if you keep very sensitive livestock, you should avoid all products that give you any concern.
