Phosphate Reactors.

[danny zubot]

I have read that they can have adverse effects on some corals.

I don't have the information to back this up anymore but I heard a reason for this a couple of years ago.

Some PO4 media use various elelments as a base which aren't good for marine aquariums. I read that some use a Mg base which can throw your other levels off, while others use various heavy metals that would only be suitable for freash water use. Sorry I can't back up this claim at this time, just offering a plausable explaination.

If you click on the link that Christy has posted above in this thread there is some good information on some of the side effects of using a Phosphate binding media. For me the benefits have far outweighed the risks.

its the type of material in the reactor that has effects on corals. if its iron based and you dont rinse it well leathers and some lps i believe dont like it.
