Phyto Carb (Aquatic Remedies)
If you want faster plant growth, richer color, and a cleaner-looking aquascape, phyto carb is a smart addition to your planted tank routine. Aquatic Remedies Phyto Carb (also sold as Phyto Carb CO2 Plus) is a liquid carbon for planted aquarium systems. It can be used with CO₂ or without CO₂, so it fits both beginner and advanced setups.
Moreover, it is designed to support healthier photosynthesis by providing a bioavailable carbon source. As a result, plants often look more active, and the tank can stay more balanced.
What Aquatic Remedies Phyto Carb does
Aquatic Remedies Phyto Carb is commonly used to:
-
Provide an organic carbon supplement for aquatic plants
-
Support stronger, steadier plant growth in live planted tanks
-
Improve the efficiency of iron assimilation in plants
-
Help reduce algae pressure when used correctly and consistently
-
Support better plant performance in low to medium tech aquariums
In other words, phyto carb helps plants compete better, which can naturally keep algae under control.
Why carbon matters in planted aquariums
All aquatic plants need carbon to grow. Usually, plants get it from dissolved CO₂. However, in many tanks CO₂ is limited, especially in low-tech setups. Therefore, using Phyto Carb CO2 Plus as a daily carbon support can make plant care easier and more consistent.
Additionally, when plants grow well, they use nutrients more efficiently. So, you often see less “waste” nutrients available for algae.
Key benefits of Phyto Carb
-
Works as liquid carbon for planted aquarium tanks
-
Useful with or without CO₂ injection
-
Helps plants use iron more effectively for better color and health
-
Can support algae control for planted tank setups (as part of good maintenance)
-
Easy daily dosing for stable results
-
Ideal for aquascapes and routine planted tank care
How to use phyto carb
Recommended dosing
3 ml per 100 liters daily or every alternate day.
Quick dosing guide:
-
25 liters: ~0.75 ml
-
50 liters: ~1.5 ml
-
100 liters: 3 ml
-
200 liters: 6 ml
Tip: Consistency matters. So, smaller regular doses usually work better than occasional large doses.
How to get the best results
To make Aquatic Remedies Phyto Carb perform even better:
-
Keep lighting stable (avoid very long light hours).
-
Maintain good filtration and circulation.
-
Do regular weekly water changes.
-
Use balanced plant nutrition (macro + micro) along with this organic carbon supplement.
-
If algae is heavy, reduce lighting and clean manually first. Then use phyto carb consistently.
Also, avoid overfeeding fish, because extra waste can trigger algae even in planted tanks.
When to use Phyto Carb CO2 Plus
Phyto Carb CO2 Plus is ideal if:
-
You run a planted aquarium without pressurized CO₂
-
You want better plant growth and improved leaf health
-
You are seeing mild algae and want extra plant support
-
You want a simple daily routine for a cleaner aquascape
Moreover, it is useful in new planted tanks where plants are still settling in.
Safety and precautions
Even though phyto carb is easy to use, dosing accurately is important.
-
Dose based on actual water volume (after soil and décor)
-
Do not overdose “to speed up results”
-
Keep good aeration, especially in heavily stocked tanks
-
Store the bottle away from heat and direct sunlight
If you keep sensitive livestock, start with alternate-day dosing first, then move to daily once everything is stable.
FAQs
Is phyto carb a replacement for CO₂?
It can support planted tanks without CO₂, and it can also be used alongside CO₂. However, it is best viewed as a carbon support product, not a direct replacement for full CO₂ injection in high-demand aquascapes.
Can it help with algae?
Yes, algae control for planted tank setups often improves when plants grow better and stay healthier. Still, for best results, combine it with good lighting control, manual cleaning, and proper maintenance.
How fast will I see results?
Many hobbyists notice improved plant “activity” within 1–2 weeks with consistent use. However, results depend on light, nutrients, and overall tank stability.
