Hello,

I am planning to set up a planted tank and took some tap water to the LFS for baseline tests. All I had tested were GH, KH and PH. GH and KH were ok, 5 and 3. PH on the other hand PH was on the high side, 8.3. I checked the city/county website and found that their goal is to raise the PH to 8.8 this year. With 1.0 PH drop with CO2 that would still be high. The water treatment plant uses soda ash, sodium carbonate (Na2CO3), to raise PH. Does this present a problem? (excessive sodium in the water) If so, how can this be corrected?

Thanks
Bill

Ok, I did some searching and sodium carbonate is no threat. the PH is still high for tetras, corydoras and the usual suspects.

Almond leaves lowers ph as well as ultum soil

I had a very similar situation when I lived in Austin, where the municipal water supplier raised the pH to around 8.8. It would drop back down to 7.9-8.0 by itself after it equilibrated with atmospheric CO2, but I also injected CO2 down to around pH 7.0. There wasn't any plant I could not grow, and kept the same school of blackskirt tetras and corys for 6+ years.

They raise the pH because iron, lead and copper are insoluble > 7.0. It's a simple and effective means of preventing those metals from getting into tap water.

Thanks for the replies. I think I'll "age" some tap water and check PH again. It would be nice to avoid doing rigorous water prep for routine water changes.

The fish i'm drawn to like soft acid water. I'm almost convinced that remineralized RO is the answer. It could give me peace of mind knowing that the water is well controlled no matter what the city does. Some posters make it sound easy.

I'm in no hurry so lots of research first.
