Purigen - Page 2

My tank is new and has been set-up about 5 weeks. The Purigen has been in about 3 weeks. I had the normal algea cycle out-break and that was while Purigen was in the tank. Didn't seem to have any affect on the algea. I've since added some Kent Phosphate Sponge and the algea was gone within 4 days.

I haven't noticed any ill effects with my corals after adding the purigen. The first hour I put it in the corals closed up but I think that has more to do iwth disturbing the water flow then the actually addition of the purigen. I have noticed soem of my corals (mainly the cabbage coral) grow a little faster. I'm ASSUMING it's because I have better water clarity so the light can penitrate a lot further.

I'm hesitant to say that the purigen made the difference between the algae growth in the tank or not since I have been working at it for a long time and there are other small routine changes I've made during the use of the purigen to help combat algae growth such as better vacuming of detritus in the tank that I think has a bigger impact.

Overall, I like the purigen for the water clarification it's done more then anything else. I will definately keep using it and plan to recharge the media within the next couple weeks to try that aspect of it. If it recharges the way it's suppose to and keeps the water clear, it'll be a perminant method of chemical filtration in my tanks. I personally find it helped my saltwater tank more then my freshwater tank.

Thanks Cougra!
The purigen does recharge as advertised (surprising in this business!). I use two 250 g bottles at a time, and find that it takes long enough to recharge the Purigen that it pays me to have four jars so that I can simply slip in two more bags and restart my filtration, then recharge the other two bags (jars) at my leisure.
I like the light idea (I have VHOs only), maybe I'll give it a try in my reef.
Thanks!
Dean

Purigen is not supposed to be a phosphate removing media nor have any effect on algae other than maybe removing disolved organics.

I've been running purigen (250ml) in my 12g nano for about 6 months now. It's my only form of filtration other than the sponge at the intake chamber. It seems to work very well. I have a second bag recharged and ready for use when the old one needs replacing. It's working to to combat an pretty high bioload for a 12g tank.

Bump!

Quick question on purigen/chemical media. If this media removes ammonia/nitrite, wouldn't this cause a general decline in the denitrifying bacteria, so that if/when this media is stopped, there will be a brief cycle as more bacteria have to grow to remove the additional ammonia/nitrite that was taken care of by the chemical media?

Witfull · 06-22-2006, 10:07 AM

when they say it removes them, its due to it removing DOC's (disolved organic compounds) same as carbon does. binding it before breakdown. but either left to long will nitrify. with carbon you replace it. purigen you recharge.

It's been three months since I've added the purigen to the tank and find that the water quality is still really clear. It's defiantely a product I'll keep using but I need to recharge the batch I have in the tank. (I still haven't gotten around to it yet). I have a second bag that I'm going to add to the tank this weekend to replace the first one while it's recharging. I'll keep an eye on the water clarity to see if there is any difference which will tell me if I left the purigen in too long or not.

12g Dude · 07-03-2006, 02:02 PM

I recently recharged a bag of purigen. Since I swap them out, I left the other to dry. I noticed that after the bleach soaking, it was bright white again. After drying, it's turned brown again. Any ideas as to why this would happen? Should I recharge it getting it to the pure white color before placing back in the tank? It was white when I bought it, I'm thinking it should be white when I put it back in.

I have tried Purigen before. I notice that it does not work for my tank. I do not get any colour change as descript by some of the pics here.

I have also tried Zeo (stone base) Nitrate removing filter media and again I find that it does not work very well too.

Now I uses the Aquamedic denitrator (deniballs base) and it rocks. It does take some time for the filter to mature and once its does, u are ready to rock and roll.
