Asked Question for Aquarium units



Q. What is reverse ?
Reverse osmosis (RO) is water purification process in which is forced through a -that removes 90-99% of water impurities. The result is that is free of and other contaminants. Membrane type the amount of dissolved solids unit is capable of . For example, Cellulose Tri-Acetate (CTA) have a removal rate of 88-94%, Thin Film Composite (TFC) membranes between 94-98% of dissolved , and Hi-S Membranes have higher rates, between 97.5-99%, and are adept at removing silicates.


Q. Why do I RO water?
Tap water often contains that can cause problems when to an aquarium. These , nitrate, chlorine, and various metals. High levels of phosphate nitrate fuel aggressive algae growth, copper, often present in water due to leaching from , is highly toxic to invertebrates. RO filters remove practically these impurities, they are more popular among aquarists, particularly hobbyists.


Q. What is the between reverse osmosis and deionization?
Reverse osmosis and deionization () perform the same task of impurities from tap water. However, purifies water utilizing the of ion exchange to remove and replaces them with pure . In most instances, an unit serves as a well-rounded method that removes the impurities; coupled with a deionization filter, the resulting water 99.9% pure. Many RO are available as a combined /unit or are able an add-on DI unit simply attaches to your existing unit.


Q. How do I if my reverse osmosis is pure?
If your RO product is pure, your aquarium should minimal algae growth, a pH level, and low phosphate nitrate levels. You can the purity of your RO water using a conductivity meter, meter, or by measuring general hardness and alkalinity of water with a test . Purified water will have a hardness of 0 GH of 0 dKH. If test values vary from above, you may need replace cartridges and/or the RO .


Q. I've recently purchased 80 gallon per day reverse osmosis and it is only 50 gallons per day. Is unit defective? if it ', why is it not producing rated 80 gallons per ?
'not likely that you a defective unit. But there a few factors that the output of reverse osmosis . These factors include; the pressure, temperature, and the of total dissolved solids within source water.

ideal operating pressure for RO (reverse osmosis) unit is 65 psi (pounds per square ). An operating pressure of 45 will reduce the output a unit by 50%. There pressure gauges available to the operating pressure of the . If the operating pressure is low, an RO pressure pump can be added to the operating pressure to ideal range. (click here for information about our SuperPump).

temperature of the source should ideally be in the 70° to 77°F range for performance. A temperature of 50°F, lower, will reduce the of the unit by 50% more. Either hot or mix of hot/cold tap water never be used for source water due to the that are added to water from most water heaters.

, the amount of total solids in the source water reduce the amount of produced by a RO unit. PurePro units are rated treat water with a dissolved amount of 500 ppm less. If your source water a higher concentration, it would wise to install a pre-filter in line prior to unit. These filters are at most hardware stores. Because the requirements of reverse osmosis , it is wise to a unit that is rated the gallons per day your needs require.


Q. Is there any I can check the of the water my reverse system is producing? Also, do I have to the membrane?
Reverse osmosis (RO) systems most of the impurities (heavy , minerals, nitrates, phosphates, and so ) in tap water, giving pure, healthy water for your . If your RO product water pure, your aquarium should minimal algae growth, a steady level, and low phosphate nitrate levels. If these conditions , check your RO product water using one of the methods:

a conductivity meter (TDS ), which will accurately measure the of impurities in the water. Whereas regular tap will have a reading in range of 300-500, purified should be in the range 5-25.

the general hardness, alkalinity, pH of the water with test kit. Purified water have a general hardness of 0 GH, alkalinity of 0 , and a pH of 7.0. your test values vary those described above, you may to replace the membrane.

lifespan of the RO depends upon the quality of source water. Under most , an RO membrane will produce 25,000 gallons of purified water last 2-3 years. However, concentrations of certain minerals such calcium, iron, and magnesium will the lifespan of the .
