While it will make better water than you're getting from your tap, it's not really what is recommended for reef tank use. And there are several things I don't much like about either system.
For reef tanks, it's best to have a system that incorporates a DI
chamber so you get water with a TDS
of 0-1. A straight RO
will usually only give you a TDS
of 12-14. A good RO
unit will have a sediment filter, a carbon block filter, the RO
membrane, and a DI
filter. These filters, except for the RO
, will be in clear housings so you can see when they're getting dirty. It's nice to have a pressure gauge and TDS
meter as well since these allow you to monitor the performance of the unit. Personally, although they are a bit more expensive than the ones you're looking at, I like the Aqua FX units best. You can go to www.aquariumwaterfilters.com
to see them or check the sponsor forums here on the site. I don't think the one you're looking at will do what you want it to.
