How do you keep the hose from clogging on your dosing pump hose. Dosing all for reef and had a hose clog basically stop the flow of liquid.
 
It’s a pain, haven’t figured out easy way to do it. Replacing hose every few months seems to be easiest solution.
 
Generally they clog at the end. You could leave the hose extra long and cut off 1/2 inch every now and again. I generally just try to pinch the hose and rinse when I see it starting to clog.

It sounds like maybe the AFR (calcium formate) is being metabolized by bacteria in the line.

You might try flushing with peroxide
 
I have my line end with a John guest connector and replace every so often
