Howdy,

I have a cycled, 23 gallon long, lightly planted tank with 11 cardinal tetras in it. Not sure if they're farm raised or wild caught. Been running for about a month and a half and the pH has been a steady 7.8. Same pH as my tap water here in Vancouver. I don't add anything to my water except prime during water changes.

Do many people here adjust their pH lower to better suit their tetras or other acidic water fish? I believe the pH has been rising over the years in Metro Vancouver tap water with an end goal of a pH of 8.

Will my tank pH drop over the next few months since the water here is supposed to be soft?

Thanks in advance!

Wow. I'm surprised your vancouver water is out of the tap at 7.8. I know a few of us are looking at more like 6.8 out of the tap in Vancouver

Maybe my API kit is testing a little high? But it's still above 7 according to City of Vancouver testing.

That's interesting. I wonder if there's others that might chime in. I don't think I've seen many posts with our local pH being mid 7's, ever.

Last time I checked my tap tests 6.6-6.8 in the lower mainland. I've definitely never gotten anything above 7

Do you live in a high rise building that has a water quality system in place?

Nope, I live in a bungalow built in 1956. Copper pipes where I can see them. Weird how everybody is still getting pH levels below 7.0 when the COV tests show above 7.0 at all their testing stations. Maybe I need to let the tap water sit for longer before I test it so any gases can escape first?

Same with me, usually my PH is around 6.6

But the main gas that would affect pH in our tap water is CO2, which would lower the pH.

I don't alter my pH, or at least not directly, but I do raise my GH and KH since our water is practically 0.

Here in North Vancouver my water out of the tap tests at 7.3 to 7.5. It used to be 8.0 to 8.5.

I talked to a Metro Vancouver official that overseas our water purity and pH: it is set at 7.0 approx.; she said whatever the pH is coming out of our taps is due to the local pipes.

My aquarium water is always trying to rise up to 7.6 and I try and keep it down to a max of 7.4 with Acid Buffer.

Really? Whenever I test, it comes out as 7 after I gassed it off.
