      THE BENEFITS OF USING CHEMIPURE (for 3 months) (absorption filtration media)Better than activated carbon Keeps aquariums crystal clear Removes dissolved organics, ammonia, nitrite , nitrate. Reduce expensive water change  Helps fish have a better appetite Eliminates osmotic shock Keeps pH stable and constant Reduces fish loss due to pH changes or polluted water Increases fish life span Filters out coppers, metals, odors and phenol Remove odor Which chemipure pack size should i get?5oz:  tank of 133L and below11oz: tank of 284L and below40oz: tank of 757L and belowEach pack will last for estimated of 3-4months Chemipure quickly filters excess waste nutrients that bacteria feed on, stopping bacteria build up and clearing your tank. Most fish tanks and aquariums become cloudy, dirty or murky as bacteria consume waste and multiply, clouding up the water. Chemipure removes dissolved organic waste, food and other particulates quickly and safely by filtering them directly from marine and freshwater tank water, stopping the bacteria build up. Chemipure is a simple-to-use filter media suitable for all types of aquatic environments, and which is manufactured with the latest technologies available. Chemipure is very economical, and provides problem-free filter operation. Chemipure is a nylon filter bag filled with a high grade blend of activated carbons and ion exchange resins. The activated carbons filter particulates and waste while the ion exchange resins help remove nitrogen (ammonia and nitrate) build up which is harmful to your fish. Chemipure also stabilizes water chemistry while keeping your pH levels perfectly constant. Its effects are far reaching, another reason why aquarists worldwide have been using it for years to help improve the life and health of their aquariums. What is the proper way to rinse Chemi Pure/Chemi Pure Elite?Put unit under running water and gently manipulate the bag until the water starts to clear. This may take up if not more than 5 minutes of rinsing. There may be some carbon residue released in the aquarium after rinsing. You may see some cloudiness; however this is completely normal as well as harmless. It will dissipate within a short amount of time. How do I judge what is the proper unit size of Chemi Pure/Chemi Pure Elite for my Aquarium? The directions say use one unit for 5 to 40 gallons. This recommendation is based on the variances of individual aquariums. For example all systems will vary depending on the actual volume of water. Which will differ due to the quantity of rock, gravel, decorations, etc.?Then you have to consider the Bio-load whether it is a heavy, overstocked aquarium versus a very lite Bio-load. These differences will also directly affect the amount of food going in, as well as the amount of waste being produced.Then take into account the variety of different filtration systems available today. Some are much more efficient than others. All of these factors will help you to determine how effective the different size units will be for your individual needs. When is the best time to change out my Chemi Pure/Chemi Pure Elite unit? Replacement is recommended every 4 to 6 months under normal use. What is considered NORMAL use? is an aquarium that is only moderately stocked coupled with adequate to really efficient filtration.Feeding habits and waste production factor into the equation as well. If you notice your aquarium start to get cloudy. Replace your Chemi Pure/Chemi Pure Elite at that time. What is the best location to place my Chemi Pure/Chemi Pure Elite unit for optimum performance in my aquarium? For Chemi Pure/Chemi Pure Elite to be most effective it should be placed in an area with a good amount of water flow evenly distributed over the unit for maximum efficiency. I have several small aquariums. I want to buy your Grande size Chemi Pure/Chemi Pure Elite and divide it up amongst them. Any recommendations on how to go about that? We do not recommend opening the units of any size of the Chemi Pure/Chemi Pure Elite units. The product is combined in such a way with the proper ratios of the different components that if altered will not provide optimum filtration. The effectiveness will be greatly diminished if not fairly useless at that point. Will Chemi Pure/Chemi Pure Elite help to set my PH in my aquarium? Chemi Pure will stabilize your PH at the level it is at when the unit is added to the aquarium. If your PH is too high or low you will need to get it to the correct level for your aquarium before adding Chemi Pure to help keep it at the level desired. Can I place my Chemi Pure/Chemi Pure Elite under my Bio ball Trickle filter? It will work fine in any area with maximum exposure and good water flow being pushed into and around the unit. chemi-pure, chemipure, chemi pure, vitachem,
