CalmedByFish Posted November 27, 2021 Share Posted November 27, 2021 (edited) My critters are accustomed to pH 7.8. In my new house, the pH is 8.3-8.4. The water I tested (twice) was tap water in a clean tank with new inert gravel, treated with a double dose of Fritz Complete, with an airstone running for 14 hours. Most of my species can adapt to the increase in pH, but the neocaridina, per Flip Aquatics, should max out at pH 7.6. (They were staying alive at the previous pH 7.8, but not breeding.) I've heard decreasing GH can also decrease pH, but I actually want to increase GH a bit. So that option is out. I know that a stable pH is safer than "chasing" pH. My KH is 9-10, so I think stability should be okay. But I'd prefer the pH be stable and lower. When I add organics (plants, fish food and poo) to the tank, to what extent might that lower pH? I know tannins can decrease pH, but I very much dislike tan water. (If needed, I could roll my eyes and keep a species-only neocaridina tank with tannins. Also, my neocaridina are actually my least-favorite species, so maybe I could very gradually let their pH increase, and just cross my fingers.) Regardless of what happens to the neocaridina, the other species I'm more concerned about are: an angelfish, endlers, platies, and green plants. If you have any further info or ideas, I'd appreciate it. Edited November 27, 2021 by CalmedByFish typo Link to comment Share on other sites More sharing options...
