View Full Version : best place to put Seachem Purigen
Hi there ive never used this product before but read up alot about it and have heard nothing but good things about it. i have a tank that is very murky, like whitsh almost, so i got a jar of the purigen and would like to know, in your opinion where would be the best place to put it for it to be most effective? i have added it to my 2nd filter chamber at the bottom where the water flows through to get to the last chamber. also how long does it take to be effective?
How exactly have you added this to your filter chamber? Is it in a bag?
Purigen works best in high flow areas....hope you got it in a baggie...or even an old stocking will do...otherwise it's gonna go EVERYWHERE!!!
yes its in an old stocking im not that blonde guys lol, i took one look at the R68 for a mesh bag and thought na a stocking will work just fine thank you hehe. azurekoi so the bottom where the water goes from one place to the other is a good spot? or should i put it in the overflow from the first chamber to the second? or in the last were the return pump is? does it work in 24H or does it take abit longer? new product lots of questions lol sorry
Anywhere in your filter will be fine (comp tank?) - as for performance - eish - depends what it's taking out...but generally 24 to 36 hours clears up most gunk...
ok cool jup its the comp tank. hmmm ok its been in for 24hr now so will see maybe by saturday how things are looking. Thanks Sean.
Hey Windfire, Azurekoi is correct, Purigen will work best anywhere there is good flow. As with other medias, the goal is to have as much water pushed through the media and as little pushed around it ( bypass). Azurekoi is also correct about the duration, this depends on what it is removing. Unlike a mechanical filter, such as a filter pad, Purigen is actively scavenging nitrogenous organic molecules and color bodies. So... if you haze is caused by a bunch of excess waste in the water, Purigen should make a difference in a day or two. If your haze is caused by a bacterial bloom or algae bloom, it will take longer as the Purigen will have to deplete the waste being utilized by such organisms. Even then, I would expect you to see a good difference in less than a week.
As for "The Bag" vs some old stockings, we developed "The Bag" specifically for regenerable resins such as Purigen. It is a Polyethylene bag with welded seams and a reusable zip-tie closure. The benefit of this is that the bag can withstand the caustics used to regenerate Purigen and other resins. So while it may be more expensive in the beginning, it last far longer than any other bag and therefore becomes more economical. I have had some of mine for well over a year and they have withstood several regenerations.
Nonetheless, thank you for using Seachem products and thank you Azurekoi for helping out!
Keep well my friends.
Hmmm, windfire, great minds thinking alike and all that - I just got some purigen and was wanting to ask where to put it in ornery ol' corner filters! So instead of starting yet another thread... Should I put the baggie above/below/between charcoal + wool? Thanks again!
I would suggest letting the water flow through the wool first, than through the charcoal and Purigen. This will remove most of the larger debris first and allow the chemical media (Purigen and charcoal) to function more effectively. Many people like to have the water flow through the Purigen last, as to polish the water right before being delivered back into the tank. The key is placing it where maximum water flows through it.
Cool thanks again! Eager anticipation of results :-D
Is there any recipe to how much purigen to use per litre of water?
Each 1 L treats up to 4,000 L of water.
Ok, so the half cup I have will treet my 280l tank perfectly. And I assume that as this is a filter media, there is no such thing as too much... although too much is probably just a waste.
That is perfectly fine! Sometimes having too much chemical filtration media (carbon) could lead to extremely clean water, which is not always a good thing in certain environments. However, since Purigen only removes nitrogenous waste, you really can't over do it.
reusable zip-tie closure
I bought the bagged type and do not recall it having the zip-tie. Did I just not pay close enough attention?
What is the zip-tie for? I regenerate mine straight in the bag. Am I supposed to take it out of the bag before regenerating?
The seperate zip bag is for when you buy it in the bottles, as it is loose. The bag type is their small one. You just regenerate it with the bag. Id love to see someone try regenerate is outside the bag... the stuff is finer than sugar.
Just remember when you regenerating it to keep swishing it, elze you dont get to generate the purigen in the middle of the bag.
Hey Tom, Zoom is on it, the prebagged 100ml sizes are sealed all the way around. We do sell a bag named "The Bag" made from the same material that has an open end with a reusable zip tie.
Some people do regenerate it outside the bag but I am also a fan of the swishing method to ensure the bleach gets all the way into the center of the bag or the media is moved from the center to the exterior. Really does depend on the size of the bag though. The 100ml size really doesn't need any help but if you have a bag packed with 500ml, it can definitely help.
ok cool thanks everyone learned alot. i'll have to see how it goes and have to decide if i move it or not though i think its in the best spot or not. thanks again guys i'll give it a week. maybe do a waterchange tomorrow
You bet, like I said earlier, the main thing is good flow. As long as the water is being forced through the media, it will do its job. Hope you all have a good night, I am going to go home and do some water changes.
Keep well everyone.
ok did a water change to help the purigen along. maybe i'll do another one on monday or tuesday. however i had the accident that every aquarist has at one point or another, i forgot to turn the heater off so of coarse added the new water and since it was really cold here today there was a sizzle and a hiss and thats the end of my heater, i will have to replace it on monday.
Can you believe it! Me too. Luckily I smelled something and took the heater out before topping up. It surely would have burst! And with the cold snap I find my heaters is batling too keep up. So I do not know how you are going to maintain heat till Monday!
TomK i was getting a lil worried so popped into a petshop on my way to watch my boyfriend play indoor football, so hopefully they wont suffer to many ill effects from the cold for the las day. i would like to add that i think winter has arrived in style!
We are sorry to hear about the heaters and hope all goes well!
Today I decided to take all the cotton wool out
And give it a clean, just a few swosh.
I noticed that there are still remaining gunk in the water.
Before I turned the pumps back on, I was thinking to add
Charcoal to remove them but didn't know where could be the
Best place, seeing all the water in the side sump chambers were
Which got me thinking, so I goggles purigen and remembered this topic
On our forum.
The product is regenerated with bleach but it says it will lose it's performance
Over time, how often is the regen process and how long will purigen last?
And how often do we need to regen it.
As stated on your website it last 6 months, is this per regen
Or the final stage of purigens life Span?
Ps hope I'm not confusing you after a
Few drinks and cough mix
BBQ, in most tanks, depending on bioload, Purigen will last abou 6 months between regenerations and can be regenerated many times. In general, you can regenerate Purigen 6-8 times. The more it is regenerated, the sooner it will need to be regenerated again. This is because the repeated bleaching process reduces the capacity of the resin over time. With that said, even after several regenerations, you will still be able to get several months of use out of the product. Some people go through 10, 12, or even more regenerations without seeing a major reduction in the time the product is active.
Also, remember that Purigen is removing dissolved organic wastes. It is not going to remove the detritus and sludge building up in the filter. The fact that this is building up in the filter is a good indicator that your wool is doing a good job trapping it. Regular filter maintenance should prevent the buildup and also help improve flow.
what caused my purigen to turn red? pls see the following link:
sorry for hijacking this thread
Oddly enough, mine also turned red. But it is still cleaning fantastically
@ shan, check out the previous link, I just posted there about red Purigen. The red coloration is not necessarily going to reduce the effectiveness of your Purigen. Really depends on what is causing the color. If it is from removing some organic, like a color enhancing nutrient, the product should last just as long as it normally does.
