My tap water is 7.4. My tanks, even tanks with no substrate are 8.3. Only water conditioners added are dechlor, and salt (1 tablespoon per 5 gallons). I tested tapwater with salt, still 7.4. I tested dechlorinated tapwater still 7.4 Any theories to why it changes in my tanks? I am not having any issues with fish, in fact our local streams are above 8.0, but I am wondering what causes this change. Any Ideas?

Are all of your tanks on home made filtration systems or are they all store bought? Could be the type of material that you use for the filter systems.

The tanks vary, but the tanks with no substrate are filtered with sponges.

:-k Do you have any empty tanks sitting around? Maybe try filling those up without any equip and letting them sit a few days...see what happens. Then you could slowly add the basic equipment you have on your most basic tanks and see after what piece the PH spikes. Just a thought.

what is your tap ph 24 - 36 hours after it come out of the tap?

could it be gassing something out?

OK right

I would still check the tap water aged 24 hours

I think he's on the right track here. I think treated water, as it ages, reverts to its "natural" state, unless it has a buffer to keep it altered. I have noticed this with my Tanganyikans. They require a high pH, over 8.0. If I put pH buffer in to raise the pH, the pH will gradually drop over the course of a week or two and revert to the natural pH of my tap water (roughly neutral). Since I put aragonite sand substrate in that tank, the pH has been maintained at roughly 8.2, due to the buffering capacity of the aragonite. I think whatever they are adding to treat your tap water is lowering the pH, and it is losing its effect and seeking the natural state of your local water.

Since you are not having trouble with your fish, I would just consider this an item of curiosity, and not lose any sleep over it. On the other hand, does anybody know of any substrate that can buffer the pH to nearly neutral?

Good question ed I would like to know if there is something that would cause the ph to be 7 or even under 7 that could be used as a substrate for my blackbanded sunfish.
