Awesome tank. I am going to get one from LFS tomorrow. To upgrade my cadlight 8 to. Just a couple of months has told me I should have gone bigger. Not sure whiich light I will use yet.

Switched from Rowaphos to the BRS HC GFO and 2 of the SPS are not happy. PE has been reduced as well on some other SPS. I went with the 3tbs recommendation from the BRS calculator and since I was going from using one GFO to another it shouldn't have made a difference but it has. I reduced flow from the reactor instead of removing the GFO along with a water change. PO4 is at .02 for the past few weeks before and after changing to the BRS HC GFO.
I am considering biopellets since it is working great in my 70G and SPS colors are looking great.

Great looking reeflove the scape!
Thank you everyone! This is as much for my documentation as to help others with ideas. More to come this year!

I feed my corals/fish daily and still have 0 phosphates and 0 nitrates. SPS are turning pale and I lost a few frags while other SPS are full of PE and growing fast.
I am shutting off the skimmer for the time being and doubling up on the feedings.

I removed the carbon and GFO completely a week ago. Phosphates were back up to .02 due to the extra feeding but I still noticed STN on a few SPS. I will only use GFO from now on if it climbs out of control. Even with such a small water volume the tank has settled in and high nitrates are never a problem. I am also fighting patches of bryopsis algae which came in on some new frags.

Thank you! The 45G will be awesome and I will keep a look out for your thread. I am thinking about redoing the aquascape and making it less cluttered.

Found the problem with my tank. It was not the GFO, Carbon, or Purigen but those did not help when nutrients went low. I ramped up the lighting to increase growth and try to get more color due to some suggestions from other SPS reefers. It worked great for the first month and growth was phenomenal but the corals used up the N03 and P04 faster than was being input into the tank. NO3 and P04 dropped to 0 and some SPS started to STN, less PE, pale colors. I chased parameters which had been extremely stable but it was a mixture of issues.
Fix:
Removed all chemical filtration, increased fish and coral feeding, reduced lighting.
STN has stopped and colors are starting to return on some of the bleached corals. CA intake nearly ceased and ALK use dropped but is starting to go back up. The tank is at .01-.02 NO3 and .03 P04 even with the extra feedings and no chemical filtration. I added carbon back in to clear up the water but it seems as if I will not need GFO unless it goes out of control. Bi-weekly water changes seem to be enough along with the skimmer.
