Hello all,
I just got a 200g box of reef crystals since I was out. I just did a PWC and tested my parameters and found the pH and dKH to have dropped significantly.
My pH is usually around 8.3 and my dKH is usually around 8-9dKH. After the PWC, my pH is now 7.8 and dKH is at 7dKH. Calcium is high at 520ppm.
I dont understand what has happend? I thought PWC would improve paramters rather than hurt them.
My tank has been up and running 11 months.
I added some dKH buffer, but from what I understand, that will only be a bandaid. I dont dose anything else. My thinking is Magnesium is low? I guess I ought to get a test for magnesium and find out? I was hoping that PWC would prevent me from having to dose chemicals. (Only a couple hard corals).
Thanks,
Matt
