Kent Marine

Description:
Kent Marine Phosphate Sponge is not an algaecide, but a ceramic medium which will adsorb phosphates quickly (within hours) when placed directly in the water flow. Works in fresh and saltwater aquariums or ponds to bring about 1.0 ppm of phosphate or silicates down to less than .05 ppm in a 120 gallon tank for every dry quart of medium. For silicate to be removed, phosphates must first be removed. Beads are cracked to expose more surface area and increase efficiency! This product will not release soluble aluminum compounds into your aquarium, causing negative reactions from your inverts, as competing products may. Will also absorb moisture for use as an air dryer for ozone, and can be renewed over and over in moisture removal service!

Directions:
Rinse with fresh water (preferably reverse osmosis or deionized water) WARNING: PRODUCT MAY GET VERY HOT THE FIRST TIME IT IS WET! Use rubber gloves and/or place in a plastic container while rinsing! Place in a large mesh bag (800 micron) or a canister filter, directly in the water flow. Make sure water flows through the material and not just around it. Leave for 8 hours to 2 days maximum (as with any phosphate adsorber, phosphates can be re-released into the system if initial charge is left in the system continuously. If you want to leave in the system to keep phosphates low or to remove silicates, replace initial charge with brand new, and change on a regular basis.) For silicate removal, phosphate must first be removed, then a new charge of Phosphate Sponge must be left in the system for several days.

Considerations for use:
Many municipal water companies add phosphates to the tap water to assist in controlling lead consumption by humans. Sodium Silicate (water glass) is also added to help reduce pipe corrosion. Phosphates and silicates also naturally occur in rivers and lakes. Phosphates and silicates are nutrients or fertilizers which, given proper lighting and other nutrients, will promote rapid growth of undesirable algae, diatoms and cyanobacteria. When used as directed, Phosphate Sponge will lower the levels of these fertilizers to help reduce growth of these unsightly nuisances. Successive replacement of charges of Phosphate Sponge may encourage a die off of hair algae!

Renewal:
For phosphate removal, renewal may or may not be possible, depending on conditions of use. At best, product may be renewed two times, depending on circumstances of use, and capacity will be much lower each time. To renew, spread 1/4" thick on a baking pan. Place in a 450 degree oven for one hour. Let cool. Rinse with fresh water and re-use. When reusing, leave for 8 hours, maximum. Do not use pan for food.

Precautions:
WARNING: PRODUCT MAY GET VERY HOT THE FIRST TIME IT IS WET! Use rubber gloves and/or place in a plastic container while rinsing!

Phosphate Sponge

I finally found a product the produces results as advertised. I've been having problems with high Phosphates in my fresh water aquarium for years. I've tried a lot of different 'remedies' but this is the first one to actually work.

Super Sponge

I have a 210 with a 35 gal sump/ref. 14 large fish and lots of corals and inverts. My Phosphates were out of range 2.5+++ I purchased 2 - large jars of Kent Marine Phosphate Sponge and put the product into my reactor and changed it every 24 hours. I cooked as described. Currently on my 2nd cook. I noticed a difference after the 1st treatment. I am on my 4th day and Phosphates are down to .54 the water is clear and all inhabitants look happy. I have tried other products over the years but this one really works as stated.

Great Product

Great Product, I use it in the CPR tumbler and it works great, as many have said before use according to the directions. If you have really high phosphates take it out closer to the 8 hour min. and if lower then you should leave about 24 hours.

Does what is says

Have a 120 gallon reef tank that had .25 ppm phosphate reading using API's test kit. Put the product in an 800 micron bag in my sump, right after the filter sock on the intake, left it in for 24 hours, reading the next day was about .05 ppm on phosphates. I have a feeling this would work even better in a reactor, but it did it's job just in the media bag. One note though, I rinsed this thing for a while in some RO water, it still clouded up my tank for a few hours, not that big of a deal but worth noting.

OMG!!!

I have NEVER had a product work as stated before. This phosphate sponge is AMAZING!!! After 8hrs of tumbling in my reactor my green hair algae started turning white. I swapped the first batch out after 13hrs and added a second batch that ran over night. The next morning ALL GHA was DEAD!!! I did a 10G WC and the tank has never looked so clean, I mean CRYSTAL CLEAR. This product is shockingly amazing and I will continue to use as needed. Please keep in mind that it needs to be rinsed VERY VERY well before adding to the tank. Even with a heavy rinse I still found that it made my tank cloudy. But nothing some filter floss and a water change didn't clear up. I also would like to mention that I saw no negative effects on corals or live stock while using this product, which is always a plus. A+++ for a great product.
