Just dose phosphates, turn skimmer off feed heavy for a bit. DinoX will raise phosphates astronomically a 100gal with zero will go to 35ppm over night with dinoX thats the only thing i really saw with usage prior, now i just dose phosphates, had them again when i started this tank. Ulva didn't detour them, i started the fuge before i cycled the tank and the ulva exploded from the ghost feedings.
