2. Clean The Pool
Reducing your pool use is a great way to save water, but stagnant pools can also encourage the growth of duckweed. You can keep your pool clean and free of duckweed by plucking it out by hand or using a skimmer. Alternatively, cover the pond with a tarp to keep off leaves that will only encourage the growth of more duckweed A tarp or cover is also a great way to reduce evaporation, which will reduce how frequently you need to refill your pool.
