Thread: pH and ORP meter

Rather than constantly observing such things, it would be better to observe the KOI itself more.
As long as that basic attitude remains unchanged, the day will not come in my lifetime when Japanese enthusiasts and you will share values.

Surely water quality is important?
I observe my Koi as often as possible even to the extent where I now have a submerged camera where I can see them even if I’m not home.
My Koi are pets and I truly care for them.

The Salt reading has never returned to 0.0 since I had it at 0.6% a long time ago, but it worked properly when raised. The Specific Gravity is not realy any use as it's forever 1.00 and the us/cm reading not important to me, maybe if using RO?

I have the probes in the clean water return from the filter so they don't get much dirt but I do clean them occasionally in a Virkon solution, they seem to be working well so far.

Thank you for this. The only time I will use ORP is if I have to use pp which hopefully won’t be for a while.
