Auto doser.... SPS now dying

[daniella3d]

must be something else. YOu would need major swing that would be obvious in tests, not what you mention.

Maybe you should test for something else, like copper.

I have had my aquarium for 2 years and half and I never checked the PH, and I am sure it is all over the place, because my KH sometimes get low, but yet my SPS are doing great. Only time I had die off and bleachign when when I used Kent carbon with copper and contaminated my tank.

It took 2 months to recover and it is still not as it was before.

If anything, dosing one large single dose will create far more swing, and dosing with a pump had brought real stability to my tank. I don't see how dosing a single dose could be any better, quite the opposite.

I wonder if the dosing is creating PH swings.

Would ph swings hurt SPS yet not my other corals In the same manner?
