In four years of running my tank I have never dosed phyto. I seem to be able to maintain an adequate pod population to feed my three pipefish and mandarin as that is all they have ever eaten for the past two years that I've owned them. I also do not have a 'fuge. Just lots of porous live rock where I can see them congregate at night. Anyway, just sharing my experience with pods and pod eaters :-)

I like dosing or feeding the tank with it. Haven't seen any troubles from it either. Won't sps pick them from the water? Chalices and such like that wouldn't mind it either. To small maybe?
