Hi everyone, I have this problem appears about two months ago. I think this is due to I changed the koi food to cheaper one. The algae is about 3~4 inches long on the wall and giving me a lot of headache because I have to clean my filter more often. Otherwise, the water will stuck. My pond is about 18 months old. The water is very clear and has below parameters: pH 8 NH4 0 Nitrite 0 Nitrate 50 ppm I always add Calcium bentonite to my pond from the beginning. Any idea how to get rid of it. Thanks
