Hi all, anyone tried this product called Seachem Purigen
Issit really that good?81Q7YvbSVIL._SL1500_.jpg
* Chemical filter media for fresh and saltwater aquariums
* Effectively removes protein and other organic aquarium pollutants
* Regenerate Purigen chemical filter media for extended aquarium use
Premium synthetic adsorbent removes soluble and insoluble aquarium impurities. Purigen is a macro-porous, synthetic polymer that removes proteins and a broad spectrum of organics at a rate and capacity that exceeds all other chemical filter media by over 500%. Controls ammonia, nitrite, and nitrate, by removing nitrogenous organic waste materials. Seachem Purigen also significantly raises redox to improve aquarium water quality and clarity.
Exhaustion is indicated by discoloration, and it can be regenerated easily. For marine and freshwater aquariums. 100 ml treats up to 100 gallons, for up to 6 months.
Directions
Rinse before use. Use 180 micron interlocking mesh bag. 1 liter treats up to 1,000 gallons for up to six months. Exhaustion is indicated by a pronounced discoloration of the beads to dark brown or black.
Regeneration
Soak Purigen in a 1:1 bleach to water solution for 24 hours in a non-metalic container in a well-ventilated area and away from children. Rinse well, and then soak for 8 hours with a solution containing 2 tablespoons of dechlorinator per cup of water. Rinse well. For freshwater use, soak for 4 hours with a solution containing 1 tablespoon of buffer per cup of water. Original color and full activity should now be restored and Purigen is ready for reuse.
Caution: Some slime coat products may permanently foul Purigen and render regeneration difficult. Do not reuse if odor of chlorine is detectable. In case of doubt, soak beads in small quantity of water and test for residual chlorine with a chlorine test kit.
General Information
Purigen is a premium synthetic adsorbent that is unlike any other filtration product. It is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others by over 500%. Purigen controls ammonia, nitrite and nitrate by removing nitrogenous organic waste that would otherwise release these harmful compounds. Purigen's impact on trace elements is minimal. It significantly raises redox. It polishes water to unparalleled clarity. Purigen darkens progressively as it exhausts, and is easily renewed by treating with bleach. Purigen is designed for both marine and freshwater use.

Excellent water polisher but you'll need to dose more fertilizers should you use it. Try to get those in filter bag packs. Last I saw them was at Seaview last week.
It works well to adsorb excess organic compounds which eventually contribute to ammonia production... ideal for tanks with higher bio-loads and need extra buffer against accumulation of organic waste.
Since it has minimal effect on chemical fertilizers, it is useful in planted tanks that dose fertilizers too (rather than carbon which adsorbs everything including the fertilizers).
The only thing is if your tank relies entirely on fish waste to generate nutrients for plant growth (ie. low-tech or el-natural walstad setups), then it may not be so suitable to use Purigen as it may soak up most of the compounds that generate nutrients, which could result in nutrient deficiencies.
Sorry hijacking! Anyone knows where selling around amk region? Also can tell me the cost for 100ml?
Not sure about AMK area, but C328 at Clementi sells the 100ml packs at around S$14 each.Originally Posted by SwordZ
Sewview sale $10
i bought mine from amazon 500ml for 21.26 US Dollar equals 28.41 Singapore Dollar

If I remember correctly, I bought the 300g, the one in bottle for either $16 or $18 at NA
UA, i just brought purigen last week, i install into my eheim pro 200 canister, i got three layer, the first layer is blue circle spong, two layer is the tray bio media/carbon media (I put on top of it) , 3rd layer is the bio media too. Is it the correct way to install the purigen? It seem like after is install it, the water become crystal clear !
Yes, thats the correct placement, the last layer (after the carbon pad), just before water flows up into the impeller area.
Btw, you can probably remove the carbon pad if its already in use for more than 2 weeks, should have exhausted its usage by then. Can create more space to enable maximum water flow through the Purigen pack.
Purigen definitely does make the tank water look much clearer, as it adsorbs alot of the suspended microscopic organic particles that would otherwise be floating around.
Oh yeah, the carbon pad i already remove it. By the way, i saw eheim white colour wool sponge. Is it necessarily to install one?
If your canister has good space, there is no harm to put more types of media inside.
This is because some bacteria may prefer different media to nest more than others, thus you end up with better bacteria filtering.
LIFE IS UNBEARABLE WITHOUT A FISH TANK!!!
What is the white sponge thingy? I dont recall having it.
Yes, fine white filter wool is usually the last stage mechanical filtration meant to trap small bits of dirt and waste debris (those that get past the coarse sponge and bio-media)... otherwise there will tend to be alot of small visible dirt and debris floating and littering about the tank.
Its one of the media that have to be replaced regularly when it is full of trapped debris and clogged up (rinsing and washing can't unclog it properly), so its a wear and tear item.
Most people just buy packs of white filter wool sheets and DIY cut them to fit their filters, much more economical than having to keep buying the original eheim ones.

Oh.. my water is very clear now, so i dont need to put also can right.. I am worried my flowrate. Last week i accidently broke my lily pipe outlet !! End up i change all back to ehiem in and outlet. Surpisely, the flow is very strong? By the way, i am using those taiwan lousy acrylic plastic lily pipe. Maybe this lousy lily pipe affect my flowrate? I am looking like Vivi brand or Gush.. but very expensive !
Last question UA, how about X303 Shiruba canister? Where should i put the purigen?
Well, its still better to put a layer of fine white filter wool in your canister filter... i find that in those tanks where i don't use filter wool, the bottom of the tank tends to accumulate alot more dirt and debris (mainly lots of poop bits from fishes and shrimps), because there is nothing to trap them and the bits just keep getting recirculated and settling all over the tank.
Btw, Purigen only adsorbs microscopic particles and organic compounds... it doesn't trap larger particles like bits of waste matter, so the fine white filter wool serves that purpose.
After some usage, you can see the filter wool gradually turn from white to dark brown between filter maintenance, it really helps to trap alot of dirt and waste debris.
As for lily pipes, their wide outlet lily shape is meant to spread out the current to create a wider flow pattern, so the current will be gentler but cover a larger area. The original eheim pipes are just a simple straight pipe outlet, so the current is stronger but the coverage is narrow.
"As for lily pipes, their wide outlet lily shape is meant to spread out the current to create a wider flow pattern, so the current will be gentler but cover a larger area."
Spray bars are better than lily pipes, but lily pipes, especially glass type, give the tank a more 'high class" look.
With spray bars, it is possible to direct the outflow near the surface in such a way that the whole tank surface is well agitated, thereby improving oxygenation. But this will be meaningless to those who don't bother much about oxygenation.
All my friends don't bother much about this aspect. But I always place oxygenation top on the list of my priorites. Everything else is secondary. I always like to take good care of my bacteria because they are the things that make a healthy tank possible.
Doesn't that mean the co2 injected for plant growth get depleted?

For that filter, the purigen pack should also be placed in the top media basket after the white filter wool pad... though the space is quite tight in that filter model, so have to remove some bio-media to create more space for the pack to fit properly.
