Pinnacle RO Unit?
Pinnacle 3-stage Reverse Osmosis (RO) units remove up to 99% of all impurities from source water for pure, clear water ideal for aquarium use.

With Pinnacle Reverse Osmosis (RO) units, you’ll help ensure pure, clear aquarium (or tap) water and promote healthy, happy aquarium inhabitants. The Seachem TFC RO membrane in each unit removes up to 99% of all impurities - including silicates - from source water. Pinnacle models filter either 35 or 50 gallons per day (gpd) with a single carbon pre-filter to ensure long membrane life and one 5-micron sediment pre-filter to remove tiny particulate matter and keep water sparkling clean.

Also includes pressure gauge, 4-way automatic shutoff valve that can be connected to an optional float valve to eliminate flooding, high-impact poly quick-fit fittings, plastic no-rust mounting bracket, and external flow restrictor. Modular design makes adding accessories easy.

One of the most important pieces of equipment to any saltwater aquarium is a Reverse Osmosis Unit. This piece of equipment greatly increases your chance for success. One of the main reasons why people leave the hobby is because their aquarium was overtaken by green hair algae.

Why Should I Use RO/DI Water?

Tap and well water contain impurities like phosphate and nitrate. Phosphates and nitrates can lead to algae blooms and headaches down the road. Even if you have well water with no chemicals, it will still have these impurities.

How Does a Reverse Osmosis Unit Work?

A Reverse Osmosis Unit pushes pressurized water through sediment and carbon filters and then through the Reverse Osmosis membrane. The Deionization stage occurs when water leaving the membrane passes over a special resin. The filters are placed in the RO Unit from largest to smallest, so the largest particles are removed from the water first. Running the water pressure at 60 PSI and an occasional membrane flush can greatly increase the life of most filters. Depending on the amount of water you use and the cleanliness of your tap or well, most filters last six months and most membranes a year.

How Clean is RODI Water?

TDS or total dissolved solids, is one way to test water purity. It measures how much stuff is in your water. This includes copper, chlorine, phosphate, silicate, iron, zinc, lead and nitrate. Typical tap and well water has a TDS of 250-500ppm. After RO purification the typical TDS is between 5 and 10ppm, and after RODI purification it is between 0 and 5ppm. As a result, algae has 25 to 50 times less nutrients that it can use to grow.
In summary, using Reverse Osmosis water is one of the keys to success in the saltwater aquarium hobby. Combined with proper filtration, this can dramatically reduce algae growth and aquarium maintenance. This will also save you from hours of frustration and wasted money. Besides a filter, this is by far the most important piece of equipment for a reef aquarium.
