2Hr Aquarist APT SKY Plus

2Hr Aquarist APT SKY Plus Discover new possibilities with SKY-boosted water. Enables shrimps and hardwater plants to thrive together with softwater plants*. Replenishes all vital minerals in RO/ RODI water without negatively altering NPK. Moderately raises KH to ~2 dKH and pH to 7.2~7.6 Each 3.5g / 5ml per 60L adds 9ppm Ca and 2.5ppm Mg (+1.8dGH, +0.5 dKH ) Recommended: 15ml per 60L of RO/RODI water. *To grow softwater plants, RO/RODI water recommended if tap water measures >2 dKH Why APT SKY PLUS? APT SKY PLUS resolves the key conundrum of how to increase water hardness (specifically as a GH booster) without altering NPK values (which interfere with the calibrated ratios of fertilisers). It moderately raises KH to ~2dKH, within the band still favoured by most commercial aquatic plants. Ingredients Ca (Calcium): 16.6% Mg (Magnesium): 3.5% B (Boron): 5mg/L Cu (Copper): 1mg/L Fe (Iron): 0.05% Mn (Manganese): 13mg/L Mo (Molybdenum): 0.01mg/L Zn (Zinc): 8mg/L Seaweed extract <1% If you have softwater or use RO water, then simply add 15ml per 60L. If you have hardwater or are unsure, obtain a GH reading using any common test kit. You can also read your local water report as we describe here . Use the Dosage Calculator (below) to determine dosage. For the very first dose, Water Volume = tank’s water volume. GH Reading is your tank’s GH level. Subsequently, during water change, Water Volume = Volume of new tap water added. GH Reading = tap water GH level. One way is to first mix APT SKY / SKYPLUS in a small container with some water and add the milky solution into the tank. Or you can simply add APT SKY / SKYPLUS powder directly into the tank. It is OK if it covers the plants. SKY vs SKYPLUS APT SKYPLUS raises KH moderately to ~2 dKH and buffers pH to 7.2~7.6. APT SKY leaves KH and pH unchanged. Use APT SKYPLUS if you keep guppies, mollies and snails. Use APT SKY if you keep tetras and rare softwater plants. Both are great for shrimp. A more detailed comparison can be found here .
