Jim TN Posted October 29, 2021 Share Posted October 29, 2021 I must say I am in a bit of shock. I used my last Tetra Test Strip a few days ago. I used my first Aquarium Co-Op Test Strip a few minutes ago. The readings are very different, though, I will say I had trouble reading the Tetra Test Strips. The main difference is the PH. The Co-Op test strip says my main community tank is Nitrate 25, Nitrite 0, Hardness 150, Buffer/KH 40, PH 6.4 and Chlorine 0. I judged the Tetra Test Strip to be around PH 7. I would prefer my PH to be around neutral. My tap water is around PH 7.6. My fish are Neon Tetras( doing extremely well ), Bloodfin Tetras, Lemon Tetras, Harlequin Rasboras and Honey Gourami. My tank is heavily planted and has a lot of wood as I feel tannins are good for fish though I realize they reduce the PH. Do I need to use Seachem Alkalinity? A water change will increase the PH but my tap water Buffer/KH is around 25. Thank you Link to comment Share on other sites More sharing options...
