System 19

I am looking to upgrade from my 58 Oceanic to the new 120 Tech Series tank and I am interested in knowing more about the skimmer in the System 19. It looks a lot like the Classic DOC which the Tunze sight says is not a good "stand alone" skimmer for SPS corals which will be the focus of my new tank. Let me know about this. I guess the System 19 looks better to me because of the calcium reactor. Thoughts please.
 
It is not a good skimmer for SPS and the calcium reactor it uses is quite old and not very strong. For a serious SPS tank to get maximum coloration you really need a larger skimmer.
 
Do you have any recommendations of a Tunze configuration that would give me the best skimmer and calc reactor combo ? Are the DOC 9010 and 9015 good for SPS ??
 
A 9010 will work but to really get the glowing colors you see in photos the nutrient level has to be very low. The corals would be healthy with a 9010 and many would be colorful but the more difficult acros will need a really nutrient poor environment to show that strong color. That generally means a big needle wheel, carbon and phosphate removers and a strong calcium reactor. I know our Master DOC's which are not out yet will work and they will fit in an Oceanic model 3, at least the smaller ones will. For a calcium reactor, our 3170 teamed with the osmolator and calcium dispenser would work as would any of the major brand calcium reactors. You will want a compartment for carbon and phosphate remover as well. You could use our 3166 filter for this but at this time it would be a largely DIY project. If you are not so intense about it and would be happy with montis and some of the hardier acros that show color in higher nutrient environments and would like some LPS, the CK16 would do the job nicely and you could just add an external or in tank calcium reactor.
