Korallin BioDenitrator Nitrate Filter S-1502 w/ Eheim 1048 Pump VS NatuReef Controlled Biological Denitrification Reactors

Anyone have any input on how these work and if one is better thant he other. I was looking at them and it seems as if the Korallin can be turned into a calcium reactor with extra parts if one wanted too. i was thinking the Natureef could be used as a dossing if you did not need it denitrifcation at some point. Anyone if anyone has some input on how they work if they are worth it and if so which is better and anything else you like to throw in.

Might look at nitra guard cubes also I saw someone on r2r started using them for nitrates

I have a 120 dule reef tank with a 50g sump. Running a pretty light bio-load. I add at least 5-10 gallons due to evaporation. So I am looking for something that may help reduce water changes down to 1 time a month or even less if possible. I am not really having issues just looking for something that will simplify my tank at work. Looking to make a system easier to maintain I guess. Not that its hard but like to get a tank to close as zero Mx as possible.
 
Having a good skimmer sure helps. Do you run a refugium? Also look into running polyfilter. I had some nasty hair algae problems, stuck some polyfilter in and "poof" two weeks later it was gone. Hasn't been back since.
 
Look into RDSBs. I suggest to run yourself a 5gallon bucket RDSB (remote deep sand bed). IT is an excellent source of denitrification and works wonders. Cheap and easy to use, barely any maint, no pellets to change, nothing to buy...just sand. Im going on about 18months of zero water changes & zero nitrates on my densely populated 300 gallon FOWLR and I feed HEAVILY 6x/day.
 
Do you have any links you can suggest to setting this up. It sounds like its worth a try since its does not cost money. Thanks for the suggestion.
 
Sure.... http://reefcentral.com/forums/showthread.php?t=595109&highlight=rdsb&page=40

Main points: Keep high flow going across the sand bed, keep it between 6"-18" deep, if you use slow flow across it make sure to siphon detritus out frequently, watch nitrates climb down, the end
 
Oh, and also its important to point out you will notice Phosphates drop as well. The sand will bind up phosphates like a sponge. Eventually it will get full and stop this absorption but it will be many years in a deep deep sand bed.
