12 Essential Aquatic Plants You Need for a Crystal Clear Natural Pool

Hardy Water Lily

Why water lilies help with clear water

A hardy water lily does more than look gorgeous. Its leaves provide surface shading plants value, which helps reduce direct sunlight and slow down algae growth.

That shade can make a huge difference in hot summer weather. I’ve seen pools look calmer and clearer once the surface light gets more balanced.

How to plant one correctly

I use a wide aquatic basket with heavy planting media and top it with gravel. Most hardy lilies like full sun and steady depth, usually around 12 to 24 inches depending on the variety.

Always check mature spread before buying. I’ve crammed the wrong lily into the wrong space before, and wow, that got annoying fast.

How much is too much

You want partial coverage, not total takeover. Too many floating leaves can block light from other helpful pond filtration plants below.

I aim for enough shade to cool the water without smothering the whole surface. Hit the next button below because watershield offers another shading option, but with a more relaxed, native-style look.
