It's interesting to see the differences in N & P uptake in otherwise
identical tanks with different plant communities. My first display featured
a wide mix of plants, but was heavy on val, hygro, sags, swords, java fern
and anubias. I was able to use the standard PMDD formulation with good
success. After refurbishing the tank last year and focusing primarily on
swords and Bacopa, I was forced to double the amount of N going into the tank
because it was being used up so fast that the plantings were looking
yellowed. Anyone else using modified versions of PMDD or finding particular
planting combinations that have special requirements for N & P?
