High PH?

So I always have an issue with the water from my tap... My PH it seems is pretty high... usually like 7.8.

What can I do about this and is this too high for a lot of freshwater fish?

7.8? I would love for my pH to be at 7.8! My pH sits at around 8.1, and the fish do not mind at all. Most fish available to hobbyists will adapt just fine.

My most sensitive species are oto cats, and they do just fine as well.I also have harlequin Rasboras, which people claim they require more acidic pH, but in my aquarium thrive. They are all healthy and vicious eaters.

Your pH is fine, do not try to add pH adjusters. You'll just end up killing the fish yourself lol. A stable pH is 10x better than the "correct" pH.

As long as you don't plan on keeping expensive, really sensitive fish, you'll be fine. A 7.8 pH really isn't that high.

Good luck!

Truer words never spoken. The only thing those "pH UP" and "pH DOWN" products are good for is the pet store's bottom line. Fish are remarkably adaptable to pH conditions, if they're stable.

My brother had a tank that got down to 4.5 before his fish started acting listless.

From my understanding certain things can help lower PH such as driftwood. Mopani driftwood I believe lowers PH but my suspicion would be just a slight bump down. The other thing I can think of that lowers PH is peat moss.

But take my info as a grain of sand as I am still new to freshwater and I am simply reading, digesting, and learning.

My tap pH is around 8.2. I keep it down to 7.6 by mixing it RO water. I use about 1/3 RO water. I started doing this more to keep the TDS reasonable and it just leveled off my pH at 7.6. The TDS from my tap is usually around 420-430. I live in limestone country!

I don't really plan on keeping anything too sensitive. So most fish can adapt to different PH?

Was just looking at my 8.1 tank and remembered making a post just like this a few months back.

Your fish will be fine, as stated a stable 8PH is far better than a 7.2-8. swinging PH.

Dead2fall, is that change from CO2? I have been told and also read that pH changes solely due to CO2 do not have as large of an impact on things as the same pH change due to other causes.

It is, but a pH change is a pH change imo. I think we all worry too much about some things honestly.

Learn something new everyday, I was sure that a drastic swing would leave everything in your tank floating....

I'm not pushing co2 and I will see a rate of .4 on a day when I test at different times.
