I have a 5000 gallon pond with 10 koi some large some small and bottom gravel filter ph has been above 9 for a while. Also have auto feeder for first time. Trying to grow my koi this year. Have food measured right so none is going into skimmer so seems to be working fine. I get lots of yard debris in the pond spring and fall and have to use pond sludge produce or bacteria to break it down. Have UV working. Clear water some white bubbles which looks like organic material is building up. My Salt level is currently .30
I am looking for help with lowering ph. I am wondering if it is my food volume or debris that is keeping my ph so high.
