Chemi-pure Blue significantly reduces organic compounds and phosphates while raising redox and helping stabilize pH for a healthy, crystal clear aquarium. Look for the new Chemi-pure Blue at a store near you. Which chemipure pack size should i get?nano pack : tank of 18L and below5.5oz:  tank of 133L and below11oz: tank of 284L and belowEach pack will last for estimated of 3-4months FAQ What is the proper way to rinse Chemi Pure/Chemi Pure Elite? Simply hold the 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 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. chemi-pure, chemipure, chemi pure, vitachem,

      NT Labs NT LABS Test Nitrite (NO2)

      3 in stock

      NT Labs Test Nitrite (NO2) is an aquarium water testing kit used to measure nitrite (NO₂) levels in freshwater or marine tanks. What is nitrite?Nitrite is produced by beneficial filtration bacteria as they break down the harmful waste ammonia excreted by the fish. Like ammonia, it is not visible to the naked eye. Nitrite is still very damaging to the health of the fish although it is not visible to the naked eye. Nitrite is then broken down into nitrate, which is harmless to the fish. What is the recommended nitrite level?A level of zero mg/L (ppm) should be maintained at all times. What do I do if the Nitrite level is wrong?If a level above 0.25 – 0.5 mg/l (ppm) of nitrite is recorded, then a substantial water change is essential. Change 25% of the water volume for 1 mg/l (ppm) nitrite and 50% for nitrite levels above this. If you record nitrite levels, it is important to check other vital water quality parameters, especially pH and ammonia. How to use? Ensure the test tube is clean. Take a 5 ml sample of water into the test tube. Add 5 drops of the Nitrite reagent. Replace the test tube cap and shake thoroughly. Wait 2 minutes, then compare the colour of the sample to the colour scale provided. Zero nitrite is represented by a colourless sample. Any hint of pink in the sample indicates the presence of nitrite in the water. Any colour forming after the two minutes should be ignored.
