How low a kh do I have to get down to before my ph will lower? I can get my kh down to 60ppm and still no ph drop. I can't solve my water problems and no one seems able to help me. I have asked many people. I live in a rural area with farms, is it fertilizer run off? I am not a chemist and a lot of the stuff you talk about is way over my head. I have plants and only DIY Co2, is my C02 inadequate? This ph problem is the same in all of my twelve tanks. I am able to spawn and raise cacatuoides and Borelli. My rams spawn and then eat their swimming fry. Is it hopeless? Do I just have to stick with fish that are not too picky about the ph? Thanks for any advice, Teresa. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
