The reactor comes complete with 2 kg of Rowalith C+ media and if you add this to one of the D-D saltwater Co2 sets then you will have everything that you need to plug and play.

Comments: The reactor work very well. HOWEVER don't try to get any service from Deltec. What a bad customer service company. Every time I called them with an issue I got NOTHING from them. Sorry but for the money what a I will look for another option.

Comments: At first I questioned myself about buying a $1000+ phosphate/carbon reactor but not anymore. The ease at which the media can be put in and taken out is amazing. The quality of the unit itself is amazing. The size is perfect because the footprint is really small. A-...the minus is the cost, but other than that nice work.

Comments: As far as build quality and performance, you can't beat it but it's achilles heal is the aquabee pump. My original pump lasted 3 months and to this date i do not have a replacement from Deltec, i was lucky enough to get the exact pump from one of the online communities otherwise i would have a useless reactor in my cabinet. if i had the to get another reactor i would go with another brand, not worth the aggrevation.

Comments: Reactor design and build are excellent like all Deltec Equipment. Reactor is easy to use with very high dKh values. Aquabee pump with my unit lasted for 4 months. 2nd aquabee went for 5 months before developing a noise due to wear on the impellor bushings. Converted the reactor to an Eheim pump. Aquebee pumps are hard to come by in the US (Cannot be purchased at Marine Depot) and all Deltec equipment uses metric PVC fittings so coverting to a different pump is not easy.
