Phosphate Question......

[Timbits]

Thanks for the reply guys, i'll be sure to test my phosphate to see where my levels are at before i start using GFO.

in regards to rinsing, would i be exhausting the media too much if i rinse it under the tap?? its going to be in a media bag. seems easier and more efficient under running water than if i use RODI, i would just dip the media bag in a container of RODI water.

and with the corals losing their colour, will all corals lose their colour?? or mostly just SPS?

i have mostly LPS and softies and just a few SPS corals.
