Auto doser.... SPS now dying

[paddyob]

Copper test negative.

I have dosed bulk for six years. This issue started when the doser began it's work. Anyone who has seen my tank knows it does great. Until now.


Ph is fine, as mentioned.

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.
