Brightwell Aquatics ChaetoGro is a complete fertilizer for Chaetomorpha and other macroalgae grown in refugiums and algae reactors. Healthy, fast-growing chaeto pulls nitrate and phosphate out of your reef – but in clean, low-nutrient systems it often stalls from lack of potassium, iron and trace elements. ChaetoGro fixes that without adding any nitrate or phosphate.
Key benefits
- 13 essential elements – including potassium (min. 1.30% as K2O), iron, magnesium, manganese, boron, molybdenum, cobalt, zinc and sulfur.
- No N or P added – feeds the algae so it consumes more of your tank's own nitrate and phosphate.
- Revives stalled chaeto – restores growth in ultra-low-nutrient reef systems.
- Safe for shrimp and other invertebrates.
How to use
- Basic: 5 ml (1 capful) per 20 US gal (approx. 76 L) twice a week for the first 2 weeks, then adjust to your algae's growth.
- Advanced: 6 drops per 20 US gal (76 L) daily.
- Shake well and add to the refugium or an area of good flow.
