It's very tricky.
Ulns must be compensated with extra food support.
But, what may appear to be ulns may not due to the measure phosphates. There are organic and non organic and only one is measured.
Best is to understand the tank.
Meassure just to interpret the signals it gives, understand them and get the numbers (and signals) you like best.
Good growth, good color, no stn = good results.
I've had great experience with almost ulns (ulns makes me rtn) and also with moderate (4/0,05) which I found best. But these levels are very important to me to keep ciano outbreaks controlled. Not just for the color of sps which is always fine.
Go on. Let's learn some more!!!
