This may have been discussed here in the past but a quick search didn't yield anything. As the title suggests I'm curious to know who doses phytoplankton, who doesn't and who used to but doesn't any more. I'd also like to know the reason for your choice and details if you do (how much, how often and what brand). General discussion of pros and cons is also welcome.
I ask because I used to but haven't for the last year. Now I'm trying to decide if I should start again.
