Ph

[Reef Pilot]

Phosphates are an ongoing battle, even with the most experienced reefers. Only real solution is get a suitable reactor and run GFO, RowaPhos or other similar phosphate remover. For initial set ups or really high phosphates, Foz Down works well. Then once it is down to near zero, use GFO or similar to maintain. Of course, you still have to keep your tank clean and don't overfeed.
