I have 2 recently cycled tanks.
Tank 1. A 3 gallon heavily planted tank with Eco complete. Ph 8
Tank 2. 10 gallon lightly planted tank with driftwood, Mopani wood, petrified wood, black river rock, Eco complete. Ph 7.6
The water is aged tap water from the same source, with Prime added. PPS Pro fertilize used properly dosed. Ammonia and nitrites in the tanks are 0. Nitrates are low.
Am I right in assuming the difference in Ph is due to the stone or wood in Tank 2 .
Is the ph likely to be less stable in tank 2.
I want to provide a stable environment for the betta I plan to buy, and don't want the Ph bouncing around, especially when I do water changes in Tank 2 using tap water with the Ph of 8.
