I'm setting up a Koi pond this summer and I'm not sure of how to do the Well water. Do I need certain chemicals or how to make it safe for Koi fish?
baking soda never got the ph to stabilize. I added crushed oyster shells and plants, let the pond run for months fishless. The next spring the ph was a nice 7.7 plus minus.pH at 5.4 isn’t good. Interferes with respiration. Baking soda with raise pH cheaply. Target 7.2.
Just remember that water has no dissolved oxygen, so spray it in when you add water.
I need to test that. I know when I pull our tap water it is 5.4 or so, last time I tested it. I do spray the water via the garden hose into the pond. It sort of waterfalls into the pond. But with the volume of the pond the low ph water going in doesn't harm it.PH will rise as tap or well water is aerated because the CO2 buildup is equalized with the above ground air.
