[AquaticLife] Eheim 2227 and PH
One thing that occurs to me. If you think that filter may have made a difference maybe you recently added it. Some of the things you can put in filters can variously pull bad things out of the water, and even change the ph (more likely by raising it). What exactly have you got in that filter?
Lenny, I take it the time of day only affects the chemistry of your aquarium if you have real plants? Or alot of algae?
Changing the way air moves through an aquarium could conceivably change the amount of carbon dioxide in the water. I’m familiar with this because my city water has an artificially extremely high ph and I prepare the water to put in the tank by bubbling air through it, and, if that doesn’t work, bubbling air from my lungs through it, to bring the ph down to that of the water in the tank. Even teh woman at the city water utility lab said that the ph is so artificially high that exposure to air lowers the ph by dissolving carbon dioxide in it. But once the water is in the tank, and I have plenty of air moving through the water in the tank, it maintains a set ph.
We’ve had discussons on these lists, and it’s remarkable what can alter the ph of your water in what ways. Not only does water from your tap differ in what could later its ph, but the structure of your tap and the way the water comes out can variously take out CO2 or add CO2. Conceivably your wet dry filter could add CO2, though unless your tank doesn’t get much air, I’m trying to imagine how that could chagne the ph of an established tank.
