Anyone Used Nualgi?
 

This stuff is like magic in a bottle, massive coral growth with some decent algae control, as a 7 month fresh reefer this stuff has helped where magnesium spiking and shade kill-off hasn't!

Looks like an $100 bottle for 500ml of silicate to encourage diatom growth. Damn! I used to get diatoms for free :p
