Daniel Posted August 27, 2020 Share Posted August 27, 2020 (edited) I hadn't noticed this until now, but the amount of Dissolved O2 in tap water is only half of water that has aged a bit. Fascinating! Source: Well water from my kitchen sink at my home in central North Carolina pH - 7.5 Nitrate - ~1 ppm Nitrite - 0 ppm GH - 300 ppm Chlorine - 0 ppm KH - 120 ppm TDS - 166 ppm Conductivity - 219 μS/cm Dissolved O2 - 4.8 mg/L Edited August 27, 2020 by Daniel The Dissolved O2 for tap water had yet to settle to the final number Link to comment Share on other sites More sharing options...
Daniel Posted August 27, 2020 Share Posted August 27, 2020 (edited) I hadn't noticed this until now, but the amount of Dissolved O2 in aged water is almost double that of well water. Fascinating! Source: Reverse Osmosis water at my home in central North Carolina pH - 6.9 Nitrate - ~1 ppm Nitrite - 0 ppm GH - 0 ppm Chlorine - 0 ppm KH - 0 ppm TDS - 28 ppm Conductivity - 43 μS/cm Dissolved O2 - 9.4 mg/L All my water goes first in to my large aquarium from the RO unit, then any water for water changes in all the other tanks comes from the large aquarium.

Alesha Posted August 27, 2020 Share Posted August 27, 2020 Central Florida, city water: Ammonia - 0 Nitrate - 0 Nitrite - 0 GH - 200-ish, most of the time, but can spike over 300 ppm Chlorine - 0 KH - 60-180, depending on when you test pH - 6.8 - 7.8, depending on when you test Link to comment Share on other sites More sharing options...
gcalberto Posted August 28, 2020 Share Posted August 28, 2020 I know my tapwater has a ph of 7,8, but it's soft and has a very low kh. That's especially bad, cause if you have any sort of log, coconut hut or Indian almond leaf in the tank the ph drops from 7,8 to 5-6,5 in about 24h, which can be challenging. Products like seachem natural regulator work way too well and have a much larger impact that it's supposed to have Link to comment Share on other sites More sharing options...
shkote Posted August 28, 2020 Share Posted August 28, 2020 My tap water in middle of farm country Ammonia - 0ppm Nitrate - 10-20ppm Nitrite - 0ppm GH - 350-500ppm KH - 100-150ppm pH - can range anywhere from 7.6-8.4 depending on the time of the year.
