So as of the beginning of this week, my aquarium water has begun to turn into this greenish tint that sometimes doesn’t let me see my fish. Any ideas of what it could be? I’ve tested my water and my readings are as follows: nitrate 20ppm, nitrite 0 ppm, GH is 150, KH is 40, and pH is 7.8. The only fish I have in this 10 gal are some harlequin rasboras and a male betta. Also I usually do a 25% water change once a week but I haven’t done one yet as I don’t know if doing one right now would help or cause more damage.
