Thanks for the condolences, but they are premature!!! No loss of fish yet. Just a lot of motionless ones at the surface.

One other observation...every few minutes somebody in the mass freaks out the others, and there is quite a bit of thrashing and jumping for a second. Then they go petrified again.

Going to have to get a more comprehensive test kit than I currently have, to see if I can find something in the water that's amiss. Going to call Seachem again to see if there might be something else that was overlooked, and I have to send back my original Purigen to them. Maybe they might be able to tell me what's going on by analyzing the bag I send them (if they will analyze it at all).

Let us know how the fish are doing this afternoon or when you can.

I would simply never use purigen again, go with regular carbon or try polyfilter pad but no more purigen.

Please keep us up to date on what seachem has to say. I'm convinced it was the purigen wether by itself or in a interaction with soemthing else. Nothing that rapid in change could of happened from simple things like bioload, filtration or anything else that fast. There was a chemical reaction somewhere.

You can have a million people praise a product, but it just takes one problem like this to really understand a product, and/or point out a flaw in a product.

I agree 100%! The thing that causes the issue is the Purigen (in concert with my particular water conditions). I'm not meaning to say that Purigen is a bad product. It works wonders for most, but it appears not for me with my particular water.

I left the bag in overnight, as before I retired for the evening a good many of the larger fish had resumed their normal habits. Some, still were at the surface, but most looked good.

So, now 12 hours later, there are still about half a dozen or so that are hiding up top in the corner, in the dark. I dumped in some flake food, 1/4 of an algae wafer and one shrimp pellet to entice them to feed, but those up top stayed there. The juveniles though were feeding like crazy along with the adults who weren't up top en masse. I also put in some food for the fry, and they also fed like normal.

The addition of the Purigen just seems to be affecting the adult guppies. The Panda Corydora, Trumpet and Nerite Snails and Red-Clawed Crab seem good. The Trumpet Snails have gone back to hiding under the gravel in the daylight, as expected.
If anything, the Purigen is having absolutely no effect on the crab. She likes to sit half out of the water, on the top of the filter pad in the filter. When I open the lid to the tank, she'll normally scurry into the exhaust port of the powerhead (big-ish square opening that overflows onto the filter pad atop the tank, and yes, one time she lost 2 legs in the impeller, but they grew back after a molt or two). Well, this morning when I went to turn on the tank's light and opened the lid, there she was, eating a small piece of carrot (don't know whether she eats it or just likes the texture, or just likes to rip things apart) on top of the bag of Purigen. Upon the movement of the lid, she waved good morning with one claw (I'll take that as "back off sucker") and bolted into the powerhead's exhaust. Yes, one day I'll put some screen over the exhaust. Sorry to digress!!!

Water parameters, at least what I can test for, seem unchanged compared to before putting the Purigen in.

I'm hoping to move into a super large tank soon. Going from 3 to 5 gallons. On that tank, I'll be able to use my Aquaclear Mini (AQ20). Then I believe I'll have good flow through the entire bag of Purigen, as opposed to the trickle through only a very, very small surface area of the bag. I'll update with any findings/observations, when I finally get that set up.

I'll also post anything that Seachem informs me of, if in fact they tell me anything.

What's in your water that could be causing this reaction with Purigen?

Curious if you have iron in your water, and if there's something that may be removing oxygen when you place the Purigen in your filter.

Unknown what might be in the water that's causing this. I figured that the water softener should be removing anything bad. Hopefully it is doing what it is supposed to.... What effect would iron have?

Today I noticed the polishing effect of the Purigen. The water is crystal clear like I've never seen before. In comparison, the water used to look yellowish, but I hadn't really noticed that until now. The water basically has disappeared from view.

Everyone in the tank seems to be back to normal except for one elderly guppy.

I had my first fatality. The oldest fish in the tank died overnight. Well, at least I think it died as opposed to it being killed. I found it above the water on a shelf that supports the filter. The shelf is still under the hood of the tank, but above water. This location is the Red-Clawed Crab's second favorite spot. The fish was partially consumed, so either he died and was placed there, or he just wasn't quick enough to escape the crab, while swimming by too close. I can't blame the death on the Purigen. He was old to the point where I was contemplating euthanizing him soon. He was struggling with his swimming, but was still going after the ladies. That alone kept me from doing it sooner. Figured I'd let the old codger sew his oats .

Package of old Purigen will ship out today to Seachem. Hopefully will know a little more in the next week or two.

Just reading this while searching for something else. Sucks that you lost your fish! Hope things have stabilized and things are thriving now.

I've got similar setups with Marineland tanks (5g and 12g), guppies and Purigen. Never had any issues, and have recharged the bags several times, sometimes a little less than once a week, when I had added new driftwood and Purigen was sucking up all the tannins.

One thing I did was actually replace the carbon filter pad with the Purigen bag, since they're both basically doing the same thing. Though I do also use a pre-filter sponge on my intake (the one for Fluval Edge works great.)

My understanding of Purigen is that, as basically a porous plastic that traps organics, it's not like a chemical that "reacts" with things in the water, so it can't create toxic compounds. It's more like mechanical filtration, but at the molecular level. You have to soak it in bleach to make it let go of the stuff it's grabbed, unlike charcoal that can start dumping toxins back out.

That said, a bag that size for such a small aquarium might have sucked up enough material fast enough that there was a noticeable change in the water quality in a short period of time. With the overstocking and you mentioning the previous yellow-ish color of the water, I just wonder if the guppies, especially the older ones, had gotten use to the "bad" water and couldn't handle the suddenly cleaner water params.

I also had a similar experience with Purigen. I just got the same package couple of weeks back upon placing it in the filter the effect was almost immediate, but my Purigen bag had a slight tear so some of the pellets got into the tank so I wasn't sure if some of the fish had swallowed them. Anyway, the effect on some of my fish was similar. Mouth half closed, slightly lethargic and one of the fish had a very fast gill movement almost like they were shaking. I thought it might because the fish ate the loose pellets. They were all fine the next day though.

I have heard from Seachem a few times since last posting. They could not find anything out of the norm regarding the Purigen I sent them. There was nothing wrong with my sample, and it performed as expected when they tried it themselves. They sent me a replacement that came in a new packaging. No more box, but now in a colorful sealed bag. I tried the new product and got the same results as with the original sample. So it's not the Purigen, but instead something in my water. The last correspondence from Seachem asked me to recharge the new Purigen that they had just recently sent to me. I've not yet had the time to do this, but will soon. I wonder what they are thinking!

Wow, I would be depressed if I came home with all of my 105 guppies dead(along with some shrimp and about 50 ramshorns).

Just to keep the record straight...I only lost one fish and he was on death's door anyway. I also don't know if he just happened to die, or if he was grabbed by my crab while swimming by.
