Ideal PH should be about 7.2-7.8. Below 6.5 kois may face some problems and die.

my ph is about 7.8

this is at the high end of the range
so I was initially a little worried
would much prefer for it to be in the middle
maybe its my over kiasi local mentality?

anyway, my kois seem healthy and fine
I read up and it seems that the worst thing is if there is a high fluctuation of ph between day and night

as long as its stable, don't change more than 0.2, its ok even if its at either 'extreme' end of the recommended range

also, I was told that ph differs depending on which part of the island you are at
I am up north, and was told that it is usually higher
not sure how accurate this is though

my ph is currently at 7.8. My koi looks fine, they are active. Anyone has any experiences on the TDS (ppm) reading in sillipore?
