All at a super affordable price! This system fits right between our 300GPD residential systems and our Blue Marlin commercial systems. Perfect for small-to-medium sized freshwater aquarium/reptile stores, or hobbyists with large freshwater aquariums. If your store sells water, we recommend upgrading to the Blue Marlin or Blue Marlin PRO for the faster water production and extra capacity. The Blue Fin RO gives you a ton of water FAST! All without the need of a booster pump. It is perfect for hobbyists that have larger aquariums as well

The Blue Fin RO also features larger 10x4 sediment and carbon pre-filters. This translates to longer contact time for proper operation and longer service life so you are not changing the filters as frequently.

* Output based on 65PSI, 77°F, 250ppm TDS water input over a 24-hour period. Lower pressure, cooler water temperature or higher TDS will reduce output. A booster pump (high-flow w/ 3/8" inlet/outlet) is highly recommended if pressure is below 45 PSI.
