I would not use this at this time, then, if you have a high ammonia level. It could react negatively with the ammonia. High pH is usually not a major concern unless you have some really delicate fish such as discus. To help lower both, do a partial water change and replace water with some bottled natural spring water, which is usually around 7,0. Additionally, it would be safer to use something all natural, such as peat, to lower the pH, in your current situation. You would add plain peat to the filter system. Look for this where they sell additional media at the fish store. And last, but definitely not least, use Tetra SafeStart Plus to help lower the ammonia by boosting your biological filter. I would do a partial water change first, to help remove some, then let the tank settle over a few minutes after adding the new water, and add the TSS Plus.
