Ulva tumble tank, unsure of appropriate nutrient concentrations

[Pastadoggie26]

I have just recently set aside a 70 gallon tank to (hopefully) be used to start a tumble culture of Ulva macroalgae. I was wondering if anyone here knew what concentrations of Nitrate/Phosphate/Potassium levels are optimal for growth and what means to use in order to achieve those numbers. Any help would be greatly appreciated ^.^

 

Thank you very much for your time!

Iron is also used by algae.

You may have more luck checking out a planted tank. They may be geared towards freshwater, but plants generally use similar ratios to grow and there's an interesting balance to keep up. There are a lot of minor trace elements needed, as well, though water changes and some invertebrates/fish to feed may help with those.
