Hi Mike,

use google translate.
I am from Bulgaria. Treat akvaristika and I want to make your pH controler.
You not write about it long time. I still use it and there need to do.

thank you

Hi Bobi,

I'm not completely sure about what you are asking, but based on the testing I've done, the PH controller design I have on my web site should work. I haven't actually connected it to a tank, so it would be interesting to hear from someone that built one of these PH controllers and actually used it.

Regards,
Mike Willegal
