If I had 50ppm nitrate in my tank, I'd be finding out why and resolving it rather than worrying about algae and taking things out of context. I did not say that high nitrtates are caused by high nutrients; nitrates of 50ppm may have nothing whatever to do with nutrients, and nutrients are absolutely required by all plants including algae in order to live, which nutrients are obviously missing in your tank since you have no algae.
DW's book is fairly old now, other ppl have continued to experiment and collect evidence also.
as you said in another thread some people will always believe the world is flat!
changing an old way of thinking, is admitting that one may have not been originally totally correct in their believes, it can be a hard thing to admit!
so i understand this. i used to think high nutrients cause algae?
tom barr being one of those sources for info, his site is quite something and the cash he has thrown at equipment to test things out, is far beyond the average aquarists capabilities
as for the bold bit above,
its the total opposite, i have ALL nutrients in abundance. along with high lighting!
if this wasnt the case i would likely get algae as soon as any one nutrient became limited.
and i'm not sure where i say algae can grow without light and nutreints...........
