You then change the media out when you phosphates are detectable or risen to an undesired level. Keeping phosphates low is the essential for growing SPS corals or LPS corals ( hard corals). It is not as important with soft corals as they tend to like more nutreints in the water, however if you have too many nutreints algea will take over. The amount used depends on the water volume of the system and the phosphate level. If your system is an average size between 30-200 gallons I think the regular sized media reactors will work fine.

Thank you so much! Been seeing those terms for months and now I know what is going on (a little bit more). I appreciate it.

I have a phosban reactor and need to trim my Xenias back once per month or they would overwhelm my tank. I have zero measurable phosphates so I can't say it is removal of phosphate alone that inhibits their growth. Perhaps it is a species thing.

I have seen people running phos so effectively that SPS won't thrive, and I have gotten my tank water so clean that even the montipora would turn pale.

There are other factors I am sure, but one factor is the amount of dissolved nutrients in the water -- apparently Xenia don't have mouths, so that may be why they use the pumping action to keep the water flowing across their bodies.

I have seen people use so much phosban that SPS would not grow and would turn pale, and I have used Vodka enough that even my montiporas would turn pale.

So for the people who are running GFO and keeping / not keeping the Xenia, I think the issue is how much phos is left in the water column.
