A: This is a very good question and it starts with testing your pond’s pH levels. The nuetral pH level in water 7.0, but if the pH gets up to 8.5 or higher it will have a harmful effect on plants. If your pH is high, you can use pH Drop to slowly bring it back down. Another thing to do is to test your tap water’s pH level. If this level is high, you may want to count on using pH Drop every time you do a water change or after it rains.
