Dosing Zeo addatives
 

I want to set up my second dose to add things like coral vitalizer, amino acids, zeobak etc. Has anyone done this before? Any recommendations?

I dose Pohl's etra via a doser, 15 ml every day. The only thing complicated about it is remembering to check the bottle to see if it's run out.

If it doesn't need to be refrigerated or shaken before each dose, I don't see why a using a doser couldn't be done for other products.
