I have 4 tanks in my house.
29 Gallon in my basement - Ph 7.5
2 gallon in my basement - Ph 8
2 gallon in bedroom - Ph 7.2
15 gallon in dining room - Ph 7.5
The two in the basement are kept in an environment approx. 55-60 degrees.
The other 2 are in living space where temp is 68-70 degrees.
I perform weekly water changes approx 20% to each tank from the same water source.
What could be the reason for the difference between the tanks?

Well, any rocks in any o these tanks? Is the water exactly the same age? Any of them planted and receiving CO2 injection?

could be what is in each tank....livestock, driftwood, filtration, amount of CO2 or Oxygen(Air Stone) that is different from tank to tank. I could be wrong but I dont think temp is a factor

Good questions.
All tanks have the same substrate. Small brown stone pebbles.
The 29G has 2 rocks in it. Sandstone.

None have CO2 injection.
2G basement - has a Whisper 40 on it, with the flow shut all the way down
29G - AC 200
2G - Eclipse explorer
15 - Whisper 20
Non have additional aeration.

What is the pH of the source water? Live plants (what species) or artificial? Inhabitants in each tank? Filter media in each filter? Open/closed tops? Feed that goes into each tank? Boxers or briefs? Oh, wait a minute... :o

Wow. So many things to consider. Seems like many things could contribute to Ph.
29G - Couple pieces of Elodea and plastic plants, 1 pleco (10"), 12 swords, 1 large danio
2G downstairs - Quarantine tank, no plants, 2 Angels
2G up - 2 plastic plants, 3 silvertip tetras, 2 danios, 1 Angel
15G - No plants, 3 Fantail goldfish
DO MOST OTHER "AQUARISTS" HAVE DIFFERENT Ph LEVELS IN THEIR TANKS?"

DO MOST OTHER "AQUARISTS" HAVE DIFFERENT Ph LEVELS IN THEIR TANKS?"They sure can, due to all of the factors we've enquired about.

Yes, because of "So many things to consider. Seems like many things could contribute to Ph." ;)
You didn't post your source water pH.

Source water - City/Public approx. Ph 8
Compare the nitrate titer of the various tanks. Partial size should be function of bioload and the resulting nitrate level in unplanted tanks, not one size fits all - it doe not.
