Boyd Chemi-pure Blue Ultimate Filter Media

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.

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.

Replacement is recommended every 4 to 6 months under normal use.

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.

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.

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.

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.

It will work fine in any area with maximum exposure and good water flow being pushed into and around the unit.
