Boyd Chemi-Pure Elite Information

Phosphates and silicates are organic compounds found everywhere in the earth. In the ocean, phosphates and silicates are formed through the accumulation of dead matter in the ocean, when too much, phosphate and silicate formation can cause death and suffocation in fishes. However, that problem is not very threatening in the ocean, because for one the ocean is very vast and wide so silicates and phosphates are spread around the body of water.

Aquariums and fish tanks are different stories. The space inside these tanks is not very spacious therefore phosphate and silicate accumulation can definitely threaten the life of your aquatic pets.

The Boyd Chemi Pure Elite Pet Store will solve this problem. This is the latest innovation of aquarium science. This product is designed to filter your aquarium by eliminating phosphate and silicate accumulation. This product is safe for use of any type of fish tank.

With the Boyd Chemi Pure Elite, you won’t need different kinds of products in your aquarium. No need for Iron Oxide removers or phosphates reactors. It’s an all-in-one, easy to maintain and hassle free product.

If you want to spend less and get the maximum results of eliminating phosphates and silicates safely then this product is for you.

Chemi-pure can be used with all water types as a chemical absorption filter and ion generator and exchange unit to positively keep pH at a perfect constant level. Also fantastic for use with African Cichlids and Discus! Needs replacement only every six months under normal circumstances. Use 1 unit up to 40 gallons, 2 units from 40 to 100 gallons, above 100 gallons add one unit for every 25 gals. 10oz. Contains 1/2 unit enough to treat 20 gallons.

Chemi-pure Elite formula now contains ferric oxide, that helps remove slime and PO4 (phosphates), giving your coral and fish a healthy environment to grow and live.

Soft corals - Crustose Coralline Algaes - Caulerpas - Gorgonias - Seafans - other invertebrates and fish of all species thrive and grow luxuriously with no water change necessary using real seawater or the better imported mixes. This is not a claim, but fact, experienced by thousands of CHEMI-PURE users. In fact, salt water fish have spawned repeatedly in 5 year old water. CHEMI-PURE does not remove trace elements and is the only filter medium which aids in the natural balance of positive and negative charges, with an emphasis on the beneficial negative ion. CHEMI-PURE comes packed in pure polyester filter bags in sealed plastic bottles, called 1 unit, one of which is recommended for up to 40 gallons of water, and which is completely active for 4-6 months with no `regeneration` or cleaning required and is cheaper than carbon or pads. The one filtration product we unreservedly recommend for use with CHEMI-PURE is the Poly-Filter, by Poly-Bio Marine! Use one pad above and one below the CHEMI-PURE bag. We also recommend the use of foam fractionation or ""protein skimmers.""

Does Chemi-pure remove trace element?
You do not have to worry about Chemi-pure removing trace elements and being a problem. Chemi-pure does contain some carbon and will remove trace amounts of some elements, but not to the extent where you would see any significant effects on any levels in your aquarium.

Will Chemi-pure raise my pH higher than it is now?
Chemi-pure works together with your waters chemistry to safely buffer an improper or low pH. It will not raise your pH from any level, but help keep it at a constant level for your aquarium.

Can I open the bag and separate the product to fit into my filter?
No, you should never cut open the bag and separate the product at all. The product ingredients do not mix evenly. If it is separated, you may not get the full benefits of the product as it is designed to do.

Where in my filter should I place the product?
Anywhere that you can put the product so it has a substantial flow of water going through the bag will do just fine. If you place in a canister filter, put a little bit of filter floss below and above the product to take up some extra room and give a nice fit.

Manufacturer Info

Boyd Enterprises Aquarium Supplies
Boyd Enterprises was founded in 1962 by Dick Boyd, who had been working in aquarium stores since 1947 at the age of 17. He had a love and passion for building and maintaining aquariums as a hobby. Through his constant experimentation to create his own filtration techniques, he developed the world renowned Chemi-pure - the original ion filter medium. In 1955, Dick Boyd along with three others founded the first Marine Aquarium Society in the United States. In 1972, he and his wife Linda, moved into a house large enough so he could build his dream aquarium. It took two years, but by 1974 Mr. Boyd had constructed a 3,000 gallon aquarium that was home to various corals, fish and invertebrates. Boyd Enterprises strives to keep up Dick’s level of Excellence, quality and customer service.

Comments: I run this in both my 55 gallon FoWLR tank and 29 gallon reef tank. My water is always crystal clear, I had a small amount of red slime in my 55 gallon. No amount of water changes seemed to get rid of it, but after adding the Chemi Pure it was gone within a couple weeks.

Comments: I have been using this as long as I can remember and probably when it first came out. I usually over do mine to keep the water quality pristine and free of organics. This is a great must have for reef tank owners. Keeps pH at stable levels as well.

Comments: Placed 3 bags (6.5oz) of Chemi Pure Elite in my sump under my sponge right before the return chamber. The next morning it looked as if my water had been polished. Through may weeks the performance remained steady. I am very pleased and will always keep bags of Chemi Pure Elite in my sump.
