Little or no PH fluxuations...

If you buffer with Baking Soda you should have very little PH swings..

Hello koiscales . . .

I'm sorry, but IMHO using BS to 'stabilize' pH in the 8.3 range is an example of treating the symptoms rather than fixing the problem -- and is not something that advanced hobbyists should consider doing.

If water quality out of the tap is adequate (pH, KH & GH), pH swings should be less than .5 per day -- even in full sun. The usual cause of pH swings (outside of unbalanced KH & GH readings) would be plants/heavy algae in the pond producing of CO2 and taking up the oxygen at night.

In this case, getting rid of the plants/algae is the proper solution -- not baking soda.

agree with Don...
got tire of adding BS. my PH been steady at 7.8, GH at 89 ppm, KH at 71 ppm for the pass 7 months w/o adding BS.

I have never used baking soda and never will. My pH is stable at 7.6.

Curious if you test your KH and what is it?

I have loads oyster shells in my shower systems. PH is steady at 7.4 with a digital meter. PH in Tapwater ranges between 8.8 and 9.5, so small water changes and the ph stays stable.

and your kh is? I don't have room for oyster shells. I add bs when I do water changes.

Don't know. Koi are happy, growing and healthy. Tested the GH a few days ago and it was way over 200. I've got to get some decent test kits for GH and KH. Maybe I'm underestimating their importance but I'm beleive with all my oyster shells (like the Japanese use them) I should be ok. Why is kh so important? It should be a seperate thread..we are hijacking this one.
