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