That is what they were meant to be when we wrote the original
article. I was very doubtful about publishing a "PMDD" recipe, because I was
afraid that people would use only that part of the whole idea.
Unfortunately, some people did just that.

That is what I have done from the start. In more than a few
postings and a lot of e-mails in response to enquiries, I have said
just that. Not surprisingly, the strategy of the original paper
leads to problems eventually, as the amount of phosphorous becomes
just too small. This may not occur if one has a heavy fish load and
lots of food going in, but that hasn't been the case with my tanks.
Nevertheless, phosphorous is the nutrient that I'm most concerned

Same here. I also add some magnesium sulphate.
