APT Sky is a specialized General Hardness (GH) booster and shrimp mineralizer developed by The 2Hr Aquarist. It is designed to restore essential minerals—primarily calcium and magnesium—without altering other critical water parameters such as KH (carbonate hardness), pH, or macronutrient levels (NPK).
This makes APT Sky ideal for use in a

Give it a go!
I wasn't expecting too much given I'm adding this to tap water, but I was wrong! I've seen a pretty profound difference in growth and colour from my pink flamingo, my red ramshorn snails are way more healthly and plant growth in general seems a lot better.
Definitely worth a try, even with tap water
