I had searched the net but was not able to see a straight forward answer.

Does using purigen in planted tank can harm our plants since it may absorb essential nutrients? anyone hee has experience of using purigen on their planted tank and share their results and experience?

Thanks

Product is a good ammonia scavenger but so are plants. Product also claims to remove,,/bind up ,,NitrAtes which plants can also use. I have used this product in non planted tanks when using an auto feeder for Fry to help with ammonia levels that may increase before I could get home from work to change water.(Discus)
In my expieience the product needs recharging monthly, depending on fish load and frequency of feedings along with waste created. If placed inside a canister filter for example, the canister would need to be opened perhaps more frequently to remove and or replace/recharge the product.
Sorry ,,I do not know what the effect of using the product would have on other nutrients added to planted tanks and thus would not use it. as mentioned,,for what it claims to remove, plants can also utilize.
Just my two cents.

Hi,

Purigen is a fine product though I do not use it unless I am dealing with a specific problem. :gw

Many aquascapers use purigan all the time. They use purigen to remove ammonia and then replace with nitrate from salts.

It makes the water crystal clear and they remove the 'trigger'

I used to have it in my filter when hi-tec but now lo-tec I don't as I now let the tank run itself plants using ammonia etc.

My short experience with it is that I have not seen any issues with plant health. I don't think it is capable of removing that much nutrients from the tank.

I am using it right now to fix yellowish water due to new driftwood and can't tell the difference for plants.

Tried it, nothing went wrong but then again, I did not notice anything "special", in my opinion, it's just another filter media.

For the price they sell it for, I would rather go with good old active carbon. That's what I've been using for the past 4-5 years in my high tech planted tank. It just works and it's relatively inexpensive. No hassle, I just pop it in the canister filter and change 50% of it or so when I notice that the water in my tank is not as clear as it could be (probably every 5-6 months or so).

I'm not saying that the fancy ion exchange resins from Seachem don't work. It's just that I believe that they are overpriced.

by the way. how much purigen to use? ammount or dosage is unclear to me in their site.

I have 7gallons of tank and the smallest amount being sold is 100ml of purigen is this enough? if more than enough, is there such thing as purigen overdose?

Just buy 100g prebagged and throw it in the filter. There is no real 'limit' Its a suggested amount.

I have a 100g bag in my little external on a 10Ltr Nanon (2USG). lol

Theres nothing special about it no. That is unless you consider uber clarity nothing special!!!. I myself and many others argued our water was crystal clear when people warbled on about purigen's abilities. How wrong we were..All of us. This is THE best polisher in the business.Removes tannins you didn't know were there.

Purigen does not leach anything in the water. It's a polymer to which molecules bind. So there is no such thing as a purigen overdose. The more you have, the longer it's going to take between recharges.

The 100 ml pouch would be fine. If it does not fit in your filter you can buy the stuff + the bag. You MUST use their bag or else you'll get a snow storm in your tank ;) (happened to me...). The stuff is very fine.

250 ml Treats 264 Gallons For 6 Months... Hmmm...

How much should I use in a 46 gallon tank?

Hi,

Seachem’s claim is that 250ml of Purigen treats up to 1000 liters for up to 6 months. :rolleyes:

A little optimistic, me thinks. :D

Purigen is good, those pillow things AC mentioned sound good, I would put a 100 ml pillow or two in the filter. I have only used the free flowing stuff and it is easy to mess up… not that… I… er, have… :eek:

I agree that it's optimistic. I have two 100 bags for my 110g and they last more or less a month. So I guess two 100 for a 46 is not exagerating if you don't plan on opening up the filter very often.

Yeah, that would be great if I could go my usual 3 to 4 weeks without opening the filter.

Biollante can you describe how you do recharge it?
When you buy the stuff it is a very close to white when it is used it turns brown.
How close to the original color is it supposed to get after recharging?
And special how do you remove the bleach out of the stuff before you use it again.

I have four used 100 gram bags lying around here. I stopped using it when the yellow disappeared.
It did that job very well.

But maybe it is a idea to recharge them en put two bags in. The filter I now use has space enough.
