Desperately Fighting Diatoms
So in my quest to find a solution to this problem, i've heard suggestions of testing my water at saltwater shops, has anyone heard of them or what i can get to test my water for phosphates and silicates? Also has anyone had any luck eradicating/controlling them? If so how? Also my tanks are not new, and i would like to find a way other than buying otos or plecs. Please help i'm desperate.
