As long as the fish are doing great and the plants growing, don't
worry about the pH. If is starts dropping below 6 and you worry
about it, put 1/4 to 1/2 teaspoon baking soda (disolved in a cup
of water first) slowly into the the tank. Don't raise the pH more than
.2 per day, however. Sounds like things are going great, good luck.
