Flourish Phosphorus, 2 L / 67.6 fl. oz.

I’ve used Flourish for years, at least a decade. It does the job and won’t harm any shrimp or snails.

Keeps your plants growing well in the aquarium. Plant nutrition is important to maintain a healthy ecosystem and needs to be closely watched. Phosphate is one of three key components to keep the plants in top shape. It's best to have a good supply on hand.
