The smarter way to treat algae.
Especially effective algae control for BBA, hair/string/fuzz and most forms of filamentous algae.
Gently biodegrades completely.
Spot-dose up to 1ml per 10L every 24 hours.
Our Standard 300ml Pack comes with a calibrated spot-dosing pipette. Out of stock in USA.
3% Epoxy Adelhydes
Power meets intelligence. The best algae treatment ever.
Above: single spot-dose of APT Fix. By Day 2, inactive BBA usually changes color to red and/or white. By Day 7, the leaf is now mostly free of algae.
Above: single spot-dosage of APT Fix via the drain-dose method. By Day 2, hair-algae has lost some color. By Day 5, all the hair algae has been deactivated.
This is an effective approach for removing algae on hardscape: wood and rocks. Avoid this method for plants.
This is our usual approach to treat algae on plants. Always pause the filter during spot-dosing. Avoid this method for treating algae on Mosses, Liverworts (Riccardia and Riccia etc.) and Vallisneria (Tape Grass).
If you have alot of areas to cover, you can exceed the 1ml per 10L limit. Spot-dose on affected areas, and perform a 50% water change after spot-dosing.
Yes, but this approach is alot less effective than spot-dosing or drain-dosing. We recommend spot-doing with the included pipette.
If your tank looks like the picture below, APT FIX / FIXLITE will not make any visible / meaningful difference. You can use a copper-based algicide, which will indeed kill all the algae. However it will also destroy the tank's bacterial colony and other plants. For such a tank, we recommend a reset.
Yes. APT FIX is an effective treatment algae control for cyanobacteria / BGA.
APT FIX contains a proprietary formulation of epoxy aldehydes.
The aldehyde components are protein crosslinkers that deactivate algae cells by binding to their proteins. The active component activates in water, but is quickly broken down by biological microbial action, resulting in no bio-accumulation in the aquarium ecosystem in the long run. This enables APT FIX to be a safe and effective inhibitor for various freshwater algae.
Both APT FIX and FIX-LITE biodegrade naturally over 12- 24 hours. So you can repeat the recommended dosage very 24 hours.
Option 1: You can exceed the 1ml per 10L recommendation to cover all areas, and do a large (50%-70%) water change after that. Be careful to use dechlorinated water.
Option 2: You can spot-dose on 1 area today, and another area the next day. Do this over as many days as you need to cover all areas. Generally a single spot-dose will be effective for any particular area. This method is slower can can be used if you are keeping more sensitive livestock.
If you are introducing new plants, or have taken out your existing plants to re-plant, you can dip your plants in an APT FIX / FIX-LITE solution before planting:
1. Create a 5% solution by adding 20 parts water to 1 part APT FIX / FIX-LITE.
2. Dip plants in solution for around 10 seconds, not more.
As usual, remember not to let the plants dry out.
APT FIX is generally stronger than APT FIX-LITE, though either can be used.
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).
Read this post on tackling algae in new tanks.
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, avoid spot-dosing APT FIX 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. Use APT FIX-LITE instead.
Perhaps. Both FIX and FIX-LITE give plants a temporary unfair advantage against algae, and this helps them recover.
However, plants that are already very weak may not benefit. In fact, FIX / FIX-LITE may affect them the same way as they impacts algae.
In a very mature tank, the signs that your plants may be very weak include:
a) Very little, or no new leaves over long periods.
b) Widespread algae on leaves.
c) Melting leaves.
Overall they might still look 'OK' but are extremely fragile. In such cases, FIX / FIX-LITE might affect them the way way they impacts algae.
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 / FIX-LITE do not harm healthy fish, shrimp and other livestock within their recommended dosage. Of course, if you keep very sensitive livestock, you should avoid all products that give you any concern.
APT Fix should be clear / grey in colour, with slight sedimentation. During production, a purple- blue dye is added as part of the manufacturing process, but fades over time. If your bottle appears purple / turquoise / blue or off-white, don't worry- the colour would fade over time. The efficacy of the product is not affected by the change in colour.
APT FIX-LITE should be slight-pink.
APT FIX / FIX-LITE should be used within 2 years of opening / first use.
The included pipette holds 3ml.
