Opinion question for you all. Is there such a thing as too many water changes?
I've been battling some low pH issues and one of the ways to reverse that is to do water changes, however I am wondering if there such a thing as too many water changes? I do a 25 to 30% water change every week vacuuming gravel every other week however my pH still is rather low and I want to raise it up.
Would I be safe doing water changes twice a week for a few weeks or without huting the bacterial colonies too much? These are all established tanks, from 20 to 55 gallons. My tap water is a bit basic, so I don't think it is lowering my ph.

Doing a lot of water changes won't hurt anything. But, when you stop doing them & go back to your regular schedule, you will see a spike in ammonia &/or nitrite.
So, I'd suggest to stay on the 2x a week or monitor closely when you stop & treat accordingly.

2x
We do water changes twice weekly.

Too many water changes could exist in a few cases:
- If it were a very stressful event for fish which aren't able to cope well with stress.
- If the water you're adding back is very different from the original parameters - large temperature swing, pH swing, etc.

Except she's only doing small water changes, 25-30%. That'd have to be a hell of a parameter difference to make an impact.

What is your ph out of the tap, and what is it in the tank? What is it in your tank that is causing your ph to drop?
-
Since it is happening on multiple tanks, not 100% sure yet, the water changes are my buffer while I try to figure it out. Ph right out of the tap is over 7.5, I'm running it aerated overnight right now to see if it drops a lot. Might be too Mapuche decaying plant matter, might also be the gravel, doing some aeration tests now. Might also be some of the drift wood, I hear oak will drop your ph like crazy. Lots of variables right now.
-
Would it be possible to add or use crushed coral exclusively as your substrate? That might counteract the driftwood/plant problem.

That is part of the long term plans. I have some cool limestone from up north that seems to be working slowly. Also going to try some fish that LIKE low PH, since I am blessed with an abundance of it.
