2Hr Aquarist APT FIX – Effective Algae Remover

2Hr Aquarist APT FIX – Effective Algae Remover

APT FIX is a targeted algae treatment for planted aquariums, built to knock out black beard algae (BBA), hair algae, string algae, fuzz algae, and most forms of filamentous algae — the stubborn types that shrugging off a water change and a good scrub-down.

What Makes APT FIX Different

The active ingredient is 3% epoxy aldehydes, which deactivate algae cells by binding directly to their proteins. Unlike copper-based algaecides, APT FIX doesn't accumulate in the aquarium environment — it biodegrades completely within 12–24 hours, so it doesn't build up in your substrate or filter media over repeated treatments.

It's applied with the included spot-dosing pipette directly onto affected areas, rather than dosed across the whole tank. That targeted approach means less exposure for healthy plants, fish, and invertebrates, and a more concentrated hit on the algae you're actually trying to remove.

Key Benefits

• Targets black beard algae, hair algae, string algae, fuzz algae, and cyanobacteria (BGA)
• Spot-dosing pipette included — treat problem areas directly instead of dosing the whole tank
• No copper or biocides — safe for repeated use at recommended doses
• Fully biodegrades within 12–24 hours, leaving no residue buildup
• Safe for fish and shrimp when used as directed

Technical Specifications

• Active ingredient: 3% epoxy aldehydes
• Spot dose: Up to 1 ml per 10 litres
• Biodegradation: Complete within 12–24 hours
• Safe for: Fish and shrimp at recommended doses
• Includes: Calibrated spot-dosing pipette

Which Algae Does APT FIX Treat?

• Black beard algae (BBA)
• Hair algae, fuzz algae, and string algae
• Cyanobacteria (BGA / blue-green algae)
• Most forms of green and red filamentous algae

Important: Do not apply APT FIX directly onto mosses (Java moss and similar), liverworts (Riccardia, Riccia), Vallisneria, or other delicate plant species — the concentrated spot dose can damage them. For algae on or near these plants, use APT FIXLITE instead.

How to Apply

1. Pause the filter before dosing
2. Spot-dose with the included pipette onto affected areas — up to 1 ml per 10 litres of tank water
3. Wait 12–24 hours
4. Perform a 50% water change if needed
5. Repeat every 24 hours if necessary

Expert Tip

Algae treatment only buys you time — it doesn't fix the underlying cause. Black beard algae and hair algae usually point to unstable CO₂, excess light, or fluctuating nutrients rather than a lack of "algae killer." Use APT FIX to clear the current outbreak, then check your lighting duration, CO₂ consistency, and dosing routine so it doesn't come straight back.

Frequently Asked Questions

What types of algae does APT FIX remove?

It targets black beard algae, hair algae, fuzz algae, string algae, cyanobacteria, and most other filamentous algae types.

Is APT FIX safe for fish and shrimp?

Yes, when used at the recommended spot dose of up to 1 ml per 10 litres.

Can I use APT FIX on moss or delicate plants?

No. Avoid direct application on mosses, liverworts, Vallisneria, and similarly delicate species. Use APT FIXLITE for algae growing on or near these plants instead.

Does APT FIX leave any residue in the tank?

No. The active ingredient fully biodegrades within 12–24 hours and doesn't accumulate with repeated use.

How often can I dose APT FIX?

It can be repeated every 24 hours if needed, though most outbreaks respond within one to a few treatments combined with a water change.

Pairs Well With

• APT 3 or APT 1 – to restore nutritional balance after treatment
• APT Pure – water conditioner for the water change after dosing
• APT FIXLITE – gentler algae treatment safe for moss and delicate plants
