So after 30 + yrs. I still dont have this figured out.
First we strive for low nutrients when starting. Then its not low enough, so we use one of the UNLS systems or now bio pellets and so forth.
Then its to low and our fancy sps dont colour up enough. So we are told to add more fish and feed more.
And in between we purchase skimmers that cost the same as my Focas.
I,m just saying.
