I think my increase in alk wouldn't have done anything as it happened slowly. I keep my temperature at 78F. My PO4 is reading high setting at .56-.22 or something like that. My clown don't bite the tips any. Any thankfully no BJD.
A couple things I did when I was finding I was having troubles. I was running about 25.5 deg celcius, I dropped this down to 25.
I also added activated carbon to it, both seemed to have helped a bit, but might've just been coincidence.
