How do I add pond plants to my Koi pond, when they just eat them all?
You can almost always add plants to your filters where the Koi can’t get to them. If that’s not possible or not enough plants will fit in the filter(s), consider adding an Active Bog, a shallow gravel-filled planting area at the perimeter where water pumped in from the pond flows through roots that pull the nutrients from the water column, effectively starving the algae. Since you pump the water into the bog it can be placed anywhere where the water will flow back into the pond, around the perimeter or even on a floating or fixed platform in the middle of the pond (Bog Islands), and your Koi can’t easily get the plants.
