Algae in your tank? Upload a photo, get the cause.
Whether it's diatoms, green algae, blue-green algae, beard algae or hair algae: upload a photo (or pick the type manually), get the algae type identified, and receive an action plan that won't put your stock at risk.

In 4 steps
How it works
1
Upload a photo or pick the type manually
The AI identifies the algae type (diatoms/brown algae, green algae, blue-green algae/cyanobacteria, beard/brush algae, hair algae), severity and affected areas. No photo handy? Manual selection works too.
2
Root-cause analysis instead of guesswork
Combines algae type, current water readings, reading history, tank age/cycling status and your stock into a root-cause hypothesis with a confidence level. Automatically recognizes when diatoms in week 3 of cycling are simply normal.
3
Action plan with a stock check
Immediate steps plus medium-term root-cause fixes (reduce lighting, adjust fertilizing/CO2, water change rhythm). Algaecide recommendations are explicitly checked against your stock – shrimp and snails are sensitive to copper, and that risk is stated, not glossed over.
4
Kick off follow-up whenever you like
If you want, log new readings and your own assessment (more, less, same – optionally with a new photo). The AI compares it to the last check-in and confirms, escalates, or adjusts the plan. After 2 good check-ins in a row, "under control" gets suggested.
What the assistant can do
More than an algae glossary
📷
Photo or manual diagnosis
Upload a photo of the algae growth – the AI identifies algae type, severity and affected areas. No photo? Manual selection works too.
🔬
Root cause instead of guesswork
Combines algae type, water readings, reading history, tank age and stock into a root-cause hypothesis with a confidence level.
🦐
Stock-aware action plan
Algae treatments are checked against your actual stock – copper risk for shrimp and snails is stated openly.
🔁
Follow-up loop
Kick off a check-in with new readings and your own assessment – the AI compares it to the last check-in and adjusts the plan.
🆓
Free to start
Photo recognition and first steps usable without premium. 5 AI analyses/month in the free plan, shared across all AI features.

Dashboard integration
An active algae issue shows up as a chip right on the tank card in your dashboard – always in view.
Why guessing isn't enough
Without an assistant vs. with Aqualizer
Without an assistant
✗Guessing what algae type it even is
✗Buying algaecide without checking your stock
✗Root cause stays unclear – algae come back
✗Diatoms in week 3 trigger needless panic
✗No way to track whether it's working
With Aqualizer
✓Algae type identified by photo (or manually)
✓Algaecide recommendation checked against your stock
✓Root-cause hypothesis from readings, history & tank age
✓Automatically recognizes "normal during cycling"
✓Follow-up check-in shows whether it's improving
Frequently asked questions
FAQ about algae in aquariums
Is diatom algae normal at the start?
Yes, almost always. In the first 4–8 weeks, new substrate releases silicic acid, and diatoms haven't got any competition yet from plants or other microorganisms. Once nitrification stabilizes, they usually disappear on their own.
Which algae treatments are shrimp-safe?
Most chemical algae treatments contain copper or other active ingredients that are toxic to shrimp and snails. It depends on the specific active ingredient and your stock – there's no universal list. The assistant checks any algaecide recommendation explicitly against your actual stock and suggests ingredient-free alternatives first.
How long does it take to fix the root cause of algae in an aquarium?
It varies: beard algae can often be removed manually within a few days, while a nutrient or light imbalance behind green algae usually needs several weeks of consistent water changes and adjusted fertilizing. No algaecide works long-term if the actual root cause isn't addressed.
What helps against blue-green algae in an aquarium?
Blue-green algae (cyanobacteria) aren't biologically algae at all, but bacteria – classic algaecides rarely work reliably against them. Common causes: too little water flow, high organic load, nutrient imbalance (low nitrate with high phosphate). The assistant assesses this based on your readings instead of recommending a one-size-fits-all product.
How do I get rid of beard algae reliably?
Beard algae (brush algae) are best removed mechanically – take out or scrub affected leaves/decor, and check CO2 supply and water flow, since beard algae often appear when CO2 levels fluctuate. The action plan lists immediate and medium-term steps tailored to your readings.
What does the algae assistant cost in Aqualizer?
Photo diagnosis and generic first steps are free to use. Photo recognition draws from the limited free quota (5 AI analyses/month, shared across all AI features). The full root-cause analysis with reading history and the complete follow-up loop are premium – or usable with the free quota too, but they use up almost the entire monthly budget at once and return a shortened answer.
