How do you lower nitrates when phosphates are 0??

[tebo]

when you say make it stronger, what you mean

more light, more flow, what do you mean exactly

[SantaMonica]

Both. Rougher screen too.

[tebo]

ok, thanks

[SantaMonica]

Also, making the light even across the screen.

My problem is not my ats, not really know if you remember but my ats its really strong, what happens is the mistake I made that shot my N over the 15 ppm and P to a little more than 0.02ppm

Already have my ATS rolling one month and has not lost anything

So the question is whether he needs more phosphate

I think SM May be referring to your earlier picture of your screen. There are two banks of fantastic " incredible hulk " growth. I think the aim would be having this growth all over the screen. Ie why is it in two banks of growth, and replicate this for the entire screen.

[SantaMonica]

No need to add P. Different species of algae grow to consume different ratios of N and P.

[tebo]

OK ok I have it
