Very nice like the sand affect and what you did with the baby tears... sweet!

Here were the tank parameters over the last month.  You have to be a little careful not to read too much into them because some of the students may not have the same "zeal" for perfection that planted tank people would

No those would be accurate readings.  My guess is that if I was using LaMotte test kits my nitrates would be around 10mg/L and the phosphates would be around 5mg/L. 

That whole high phosphates causing algae thing is a myth.  Actually it is the phosphates which drive the biochemical side of the photosynthetic reaction
