Cloudy Water in New Koi Pond: Barley Straw and Plants

New Pond, Cloudy Water: Patience and Plants

4-week-old pond with 5 baby koi, tadpoles, cloudy water despite filter cleaning. This is new pond syndrome—bacteria and algae blooms before equilibrium.

Quick Fixes

• Floaters: Water hyacinth, lettuce (shade, nutrient uptake).
• Barley bales (brick-sized) — sink in pond; replace as they decompose.
• Stop cleaning filter daily — you're removing beneficial bacteria.

Don't Add Chemicals

Algaecides, flocculants, etc. disrupt the cycle. Let nature establish.

Cloudiness usually clears in 4–8 weeks with plants and barley.
