About this aquarium plant food

Potassium Nitrate is the backbone of the PPS-Pro macro bottle. It’s the primary source of nitrogen in the system — the nutrient that plants consume in the largest quantities and the one most likely to run out first.

Nitrogen drives everything you can see above the substrate. Leaf growth, stem strength, the deep green colour of healthy plants — all of it depends on a consistent nitrogen supply. When nitrogen runs low, plants go pale and growth slows noticeably. It’s usually the first deficiency you’ll spot, and the easiest to fix.

When your macro bottle runs low, this is likely the first compound you’ll need to replace. Buy it individually and top up without having to replace the whole kit.

How to use

Mix into your macro bottle with the other macro compounds using the instructions supplied with your order. Dose the mixed bottle at 1ml per 10 litres daily.
