I then converted to using a dry salt like substance called Acid Buffer made by Seachem. I pour just a few grams in each day, I have been using this product for four days and have had a small fluctuation in my PH.
I would rather leave the PH alone but was under the impression that the fish were in distress if the PH was not at or near 7 ppm.
Byron- YES! I would LOVE to know more about the proper fertilizer balances. THANK you so very much!!
I have to go offline momentarily, but will be back tomorrow. I'll deal with the plant nutrient issue then. In the interim, can you find out from the water supply people (they may have a website) what the GH (general hardness) and KH (carbonate hardness or Alkalinity) are? The latter is a buffer for pH, which is why chemicals do not work. Fortunately, there are no fish in this tank, at least i am assuming that.
All fish have a preferred GH and pH range at which their internal physiology, called the homeostasis, operates at its best and most effective. So a pH of 7 is not the aim, but a pH closer to the fish's requirement. There is some adaptability in some fish. If you know what fish you'd like to have, check their profiles (second tab from the left in the blue bar across the top of the page), all this data is included for each species. It is easier to select fish suited to your source water than it is to adjust that water to suit sensitive species, though this is possible.
