Low pH/kH in Water, Low = Bad? Options

[bekko]

There is nothing wrong with a pH 6.5 unless it is an indication that your pH is falling and could crash. The fact that your pond and tap are the same indicates that your water exchange is sufficient to keep up with the production of acids by decomposition of organic matter.

Goldrush is probably right about the meter/kit. You can check your equipment against a saturated solution of baking soda in distilled water and it should read eight-point-something. Where's CP? What's that number again? Where's that thread?

8.4

Here's where I started and how CP elaborate further with his test:

Hi,

I test my water is around 6.5 ! Same result as tap water !!
Can someone tell me how can bring up the PH beside baking soda ?
I heard coral chip or oyster shell can do that, is it true ?
And how can I get them and use it ?

Appreciate your help !

First and foremost pH 6.5 is fine.

Coral chips or oyster shell can bring up pH FROM 6.5, but both has different saturation points in which the exact figure I am not very sure.I suspect oyster shells brings it up to around 7.8.

Coral chips can be purchased in most LFS, oyster shells you can get from Max Koi Farm.

Thanks guys !
I learned something new today !

Last night, I used AP fresh water master test kit to test my 90 gallons fish tank, the PH result came out 6.0 !
I used BS buffer up to 7.0 for temporay.
I think I will try to coral or oyster shell later.

Cp, you have amazing setup for your fish tank !

This website is great, I always learn something new from you guys.
Thanks again !

in being a water keeper I have learned that the bacteria in the filter is happier and actually does a better job in the 7.2-7.4 range. also that the higher the PH the more damage Ammonia can achieve...what do these two consideration have as to weight in keeping goldfish water
