So I started my reactor with gfo/carbon mix about a week ago and now the polyps on both of my finger leathers are not opening and my hammer, candy cane and pearl bubble corals are not opening up fully...what could be the problem? They started showing some of these signs before I started the reactor (which is the reason I got it in the first place) but things are not improving...I started getting lots of algae so i thought my phosphates were getting too high...I dont have my skimmer yet, could the carbon from the reactor be having a negative affect? Any help would be appreciated! Thanks

did you mix gfo and carbon? I thought that was meant to be avoided as they require different flow and maybe another couple of reasons?

Have you tested parameters?

It was my understanding that you can pack gfo with carbon to prevent it from clumping up...its on the brs website... and the tests that I have are all ok except nitrates are pretty high right now (hence the reason for getting a skimmer) I do not have a test for phosphates...

I think you have answered your own question While nitrate and phosphate won't harm your fish, they will affect your corals.

There could also be some precipitate from the GFO and GAC that is in the water column. Do nothing more than a water change and see if there is any change.

+1, I agree with everything 50seven said. WC to remove any particulate that may have made it into the water column and to reduce nitrates and phosphates - these 2 are the main levels to watch when caring for corals.

Perfect thanks guys I will do that and let everyone know the outcome!

When you first bring carbon and GFO online, start at a very slow flow rate. Adjusting it higher as time goes.

Oops deeznutz I didnt do that...what can happen?

What has already happened. They'll be fine though. Just don't neglect those WC's.
