My Koi/Goldfish keep dying!
Can anyone give me any suggestions as to why my Koi
keep dying, Probably about 25 in total in a month! Our pond is about 2000 gals, has a waterfall, fountain, filter, lots of plants for cover and lots of oxygen plants. Whenever we have to fill it, I put declorinizer in. I bought a test kit, ended up being for an aquarium, but I assume it doesn't make much difference. I tested Ammonia, it's at 0, the Nitrate is also around 0, and so is everything else, except for the ph, it looks like it's really high, it's hard to tell because the colors on the chart don't match the actuals colors at all, but it looks like it's off the chart, which ends at 9. So I bought a $35 container to lower the ph by 0.2 a day, but I need to use 16 scoops of it a day, and thats almost the entire bottle, so it would cost me $35 a day! Does anyone know if it's the ph that is killing my fish, and if so how can I lower it? Or does anyone have any other suggestions as to why my fish are dying?
