Purigen in a Planted Tank?

Hi all,

It seems a lot of people sing the praise of Purigen and use it in their filters. In a planted tank, wouldn't this be counter productive by soaking up the NO3 required for the plants? I was looking at getting some as I always have high nitrate levels, but more live plants would probably help more!

Cheers,
Dale

If you're nitrate comes from an organic source ( decomposing food and plant material, fish waste, etc. ) then, yes, it will remove nitrate. If your nitrate comes from an inorganic source such as KNO3 then, no, it won't remove it.

@DaleM adding Purigen will not reduce NO3 or absorb it.

Purigen is an organic scavenging resin, it will collect dissolved organics preventing them from entering the nitrogen cycle.

As @Jeff5614 said KNO3 will not be affected.

Two points:

1) The marketing hype is that Purigen removes decaying organics before they decompose into nitrogenous compounds and produce nitrates. Back when my tank was fish only, I used Purigen (two pouches in my 60g) with another two for instant replacement as needed. Oh the material turned brown indicating it was collecting detritus, but I never saw it reducing tank generated nitrates at all!

2) After a long period of use, I found that Purigen was no better at promoting clear water than simple polyester filter floss. The Purigen pouches were retired to a storage bin. With the heavily planted tank, I just use bio-sponge material in filters...and the water is crystal clear.

(Note that on occasion I do use a Marineland Magnum Polishing Internal Canister filter with the micron cartridge charged with diatomaceous earth - nothing beats occasional DE filtration).

Disclaimer - I have no affiliation with Seachem or Marineland other than a purchaser of their products and receive nothing for mentioning the product(s) they produce.

I love using Purigen because it really helps polish the water well and I feel that it helps improve water quality. It isn't a cheat code to get you out of proper husbandry, but the stuff works well.

Do water changes to lower nitrate levels. When was the last time you cleaned your filter or filters? People tend to ignore those so they end up turning into nitrate cesspools.

AbbeysDad likes to keep 'mulm' AKA a layer of sludge in his tank, so adding Purigen Chemi-Pure Green or any other form of 'carbon' isn't going to do anything as the sludge is always there polluting the water. Snail poop regardless of the species of snail being kept contributes to the sludge factor.

Purigen, Chemi-Pure Green ( it is called that because it is plant friendly), ect... do well in tanks that are maintained. People tend not to use them that way though. They think if they put stuff in a filter that it will act like a magic wand so they don't have clean their tanks. None of them work that way. If that is your intention, you may as well throw your money out a window.

Well, it's just one of those days that doesn't happen often, but I'm afraid I'm going to have to agree with my dear Smooch. Purigen, Chemi Clean, activated carbon, etc. are just a tool in the belt. Those along with good tank maintenance such as regular water changes, removing decaying and dying plant material and detritus that doesn't make it to the filter, regular frequent filter maintenance, etc. keep DOC's to a minimum. You can't toss in some Purigen, stop with regular maintenance and expect your tank to stay clean.

One is chemical and the other mechanical so the latter wouldn't do much until it was removed from the fiter.

I agree, but I'm trying to find where someone said they were relying on just the Purigen.

I don't think anyone did say that, but I was so shocked that I agreed with the general idea that Smooch posted I just had to mention it.

I've been using Purigen for quite some time. Also run a UV sterilizer. And perform loads of tank maintenance. Kind of the everything but the kitchen sink approach.

However, in the interest of seeing if any of it really matters, I have been weaning myself off Purigen. Used to run it in all three filters. Have been removing it from one of the filters every two weeks, and am down to one now. So far I have seen no noticeable difference. We'll see once I remove the last one next week then run it without any for awhile.

Not to say I won't go back to it, just trying to determine if it's really doing anything or not.

Same for the UV sterilizer. Used to run it only after a water change, then just started leaving it on. Once I get past the Purigen weaning, that thing is next.

My suspicion is neither is doing a great deal, but I am going to find out.

I use it in one of my tanks. It definitely helps to polish that last bit that passes through mechanical. I find that those little pouches need re-charging more frequently than seachem lets on but it's easy enough to do. Every other diffuser cleaning I re-charge the purigen, so like every 6-8 weeks. I'm sure tank size, stocking, biomass, etc. all determine how long it remains active.

Does purigen remove meds like carbon does? Does anyone run both? No chemical filtration on my 55 right now, but running preventative meds right now so will need to order something by tomorrow to have it by the weekend water change.

I would remove purigen and use carbon to remove medicines... especially ones with copper in it. Purigen is intended to remove organic waste, not inorganic based or metals.
