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...

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 UV? Although we can't see UV light, we are exposed to a small amount every time we step out into the sun. In fact, UV light is responsible for sunburns. The water treatment industry uses special lamps that emit UV light of a particular wavelength in order to disinfect water. UV light works by attacking the genetic core (DNA) of bacteria and viruses, destroying their ability to function and reproduce. The process is simple but effective: our systems destroy 99.99 percent of harmful microorganisms without adding chemicals or changing your water's taste or odor. From Wikipedia.org - Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400 nm, and energies from 3 eV to 124 eV. It is named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the...
