APT SKY PLUS solves the key puzzle of how to increase water hardness (specifically as a growth hormone booster) without changing NPK values (which interfere with calibrated fertilizer ratios). It moderately raises KH to ~2dKH, within the range still preferred by most commercial aquatic plants.
APT Sky Plus Benefits
- Allows for the co-cultivation of soft and hard aquatic plants.
- Improves the health and reproduction of shrimp and other invertebrates.
- Compatible with aquariums using CO₂ systems where pH stability and low KH values are essential.
- Easy to dose and fully soluble.
Recommended APT Sky Plus Dosage
- If you have soft water or use reverse osmosis water, simply add 15 ml per 60 liters.
- During weekly maintenance (water change), add the same dose only to the replaced water (newly added) in the aquarium.
One way is to first mix SKY PLUS in a small container with some water and add the milky solution to the aquarium.
Or you can simply add SKY PLUS powder directly to the aquarium. No problem if it gets on the plants.
Use APT SKY PLUS if you keep guppies, mollies and snails. Use APT SKY if you keep tetras and rare plants that prefer soft water. Both preparations are great for shrimp.
