2Hr Aquarist APT SKY
€12,90 - €44,90
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 with no negative altering of NPK, KH or pH.
Each 3.5g / 5ml per 60L adds 12ppm Calcium and 3.5ppm Magnesium (+2.5 dGH)
Recommended: 15ml per 60L of RO/RODI water.
*To grow softwater plants, RO/RODI water recommended if tap water measures >2 dKH
#Mini70g
This size is not available in US and Europe.
Why
APT SKY 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) and KH (where higher values are not favoured by most commercial aquatic plants).

the weather at your command
Enjoy the freedom to breed shrimps in softwater tanks, and have hardwater and softwater plants thrive side-by-side.
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.

hardwater / softwater 101
Plants have conflicting softwater / hardwater requirements.
APT SKY and APT SKYPLUS remove the hassle of having to choose between softwater and hardwater plants. For softwater tanks, it boosts shrimp health and reproduction.
The catch? It does require Softwater or Reverse Osmosis (RO) water to begin with. At the moment, there is no easy way to make Hardwater ’Soft’.
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.
smart savings
As a GH booster, APT SKY is ~ 3X as concentrated as conventional remineralisers. Each 3.5g / 5ml per 60L adds 12ppm Calcium and 3.5ppm Magnesiumm, raising GH by 2.5 dGH.
Did we mention that it is super-soluble, non-caking and just a joy to handle?

Is low pH in tanks due to aquasoils/softwater a concern?
Tanks using aquasoil in softwater countries naturally have very low pH values. This usually sparks some concern among the aquarist crowd which worry that such a low pH will affect livestock or bacteria health in the tank...
