100% pure bio pellets, Which is all we sell at www.purelyh2o.com, help remove nitrate and phosphate from your Reef saltwater aquarium so these nutrients are not available to algae and other organisms .the process is to convert  the nitrate and phosphate in the reef aquarium water into bacteria cells that are then removed from the aquarium by a protein skimmer or cleaning your mechanical filter. Nitrate and phosphate are nutrients and can only be removed by water changes with a Reverse Osmosis or RODI Filter System or by having some organism consume it. In most aquariums without plants as competitors, algae will consume the nitrate and phosphate resulting in a tank full of unwanted and unsightly algae. In a great deal of  marine aquariums cyanobacteria, which grows like a red to black carpet over the entire aquarium, will consume the nitrate and phosphate. To grow algae and bacteria you need carbon, nitrogen (nitrate) and phosphorus (phosphate). Studies show that many man...

Q) Does reverse osmosis remove parasites?A) The largest allowable pass through in a reverse osmosis membrane is 1/10,000th of a micron. Thesize suggested by the NSF to remove parasites is 1 micron. This makes the filtration quality of reverseosmosis 10,000 times better than the recommended value! Q) Where does the TDS go after the RO removes it?A) The RO membrane has the ability to clean itself. The particulates in the water are flushed down thedrain. This is why the RO membrane lasts so much longer than the other filters in the system. Q) How much water does this system waste?A) the typical waste to product ratio for a reverse osmosis system is 4 to 1 under the correct pressure.The ratio will change in favor of the product as the pressure increases. There are other ways to improvethe waste to product ratio as well. Please call us at (877) 803-7462 if...

Helpful information when troubleshooting your RO/DI System Milky colored water. This is normal for a new system and will go away after a week or so. If thiscontinues beyond that time please contact us. Drain keeps  running. There are several reasons why this might happen. #1 – You may have purchased a system that does not include an auto shut off system. If you are unsure, please contact our support department. #2 – Your system pressure may be too low and you may need a booster pump for your system to operate correctly. #3 – Your system may have a clog or a leak. Check to make sure that all of your hoses are free of kinks and there are no puddles around the system. Funny taste or smell. If your system begins to put off a foul odor, you may need to change filters and or sanitize the system...

Reverse osmosis is often used in commercial and residential water filtration. It is also one of the methods used to desalinate seawater. Sometimes reverse osmosis is used to purify liquids in which water is an undesirable impurity.Reverse osmosis occurs when the water is moved across the membrane against the concentration gradient, from lower concentration to higher concentration. To illustrate, imagine a semipermeable membrane with fresh water on one side and a concentrated aqueous solution on the other side. If normal osmosis takes place, the fresh water will cross the membrane to dilute the concentrated solution. In reverse osmosis, pressure is exerted on the side with the concentrated solution to force the water molecules across the membrane to the fresh water side. Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration. Osmosis is a special case of diffusion in which the molecules are...

What Is Reverse Osmosis? In order to reverse the natural tendencies of water and salt movement and force clean water to flow from salty water, the osmonic pressure must be overcome, i.e. osmosis must be reversed. In order to reverse this flow of water, membrane systems, and Reverse Osmosis systems in particular, utilize a special constructed semi-permeable membrane element enclosed inside a pressure vessel. Pressure is applied to reverse the flow of water, the source of which is usually and existing, pressure is applied to the feed stream, water molecules are passed through the membrane while salts are retained in the feed. Thus, utilizing the principles of water and salts movement, and combining them with pressure and membrane technology, the natural osmotic flow of solution is reversed. How a membrane separates substances Metals, Organic compounds, and other contaminants are either too large, or due to their chemistry unable, to pass through...

De-ionization, (commonly referred to as DI), is a common process for producing ultra pure water. The DI filter is filled with resin beads, some with a negative charge and some with a positive charge. When you test your water with a TDS meter (total dissolved solids), it gives you a number that tells you the sum of the different contaminates in your water. All of these contaminates are either negatively or positively charged, so when they pass through the DI filter they are attracted to the oppositely charged resin beads. Since the DI filter has both negatively and positively charged resin beads it is able to remove 99% of the contaminates in your water. Reverse Osmosis (RO) is capable of removing 95-97% of all contaminates, so when the remaining 3-5% is passed through a DI filter you are effectively removing 99.9% of the contaminates. This quality of water is comparable to...
