They seem to imply as little as possible/none. I read one answer to someone having algae problems; part of the answer was to reduce phosphate levels; the suggested maximum was 0.15ppm of phosphate, supposedly because even 1ppm of phosphate caused problems.
Basically they are of the 'nitrate and phosphate is evil' brigade; I'm sure they would probably recommend phosphate removers etc.
i.e. pre-PMDD day thinking? (please note also that I was only shaking my head in 'mild' anger :p )
What I meant was that when they said 'excessive' they would be talking in the >10ppm & >1ppm levels...
PS how much nitrate do you need to add to get algae? I'm sure Tom Barr said he once added 70ppm+ and got none...
