I have had a nextreef pellet reactor for about 4 months now and I love it! My nitrates were between 40 and 80 ppm becasue I feed alot and have alot of fish. I could not keep SPS in my tank because they would just die. I didnt want to give up my fish either and this was my answer to "having my cake and eating it too". Now with a 100g system I am successfully growing beautiful SPS and I have all my fish and I feed every day. NO3 is 0 and PO4 is 0! My softies and my LPS shriveled up for a couple of weeks after running it a month because the water quality changed for the better but they ALL bounced back and are growing faster than ever.

The only down side to having a bio pellet reactor is, I got a case of cyano. It was not bad and it would start to grow and then die so it could not get a foot hold on my tank. It didnt make sense to me because NO3 and PO4 is 0. I learned that the pellets provide a carbon source for the cyano to feed on. That is why its important for the outlet of the reactor to be near the skimmer and its also important to not have the flow to the reactor too high. I recently buy a ball valve on the pump line to the reactor and problem solved. Personally I recommend having bio pellets if you want lots of fish and SPS without having to do mass water changes every week. I havent done a water change in about 2 months on my tank because it does not need it. I dose fuel and feed coral frenzy everyother day and everything is happy.
