several of my corkscrew vals have been starting to turn all brown and dieing. not sure whats up with it.

what are the general causes for this? I will post pics tomorrow if necessary.

along with my algae issues, something is definately up in this tank! gotta figure it out soon!

Notes:
Dose more than EI recommend (high PO4, high NO3, high K, 2x Traces, etc etc)
co2 = 60ppm
lighting is under dispute :gw but I have 260w over a 1/2 full 110g tank
