Purigen vs. Carbon for shrimp only tank

I researched about purigen and carbon. The only advantage Purigen has over Carbon that it can be recycle/recharge. Carbon will end it life once it's being used up.

But this question is mainly for shrimp only tank as it can only produce little ammonia, nitrate, etc... Will it make a big different if I use Purigen over Carbon. Since the Purigen usually cost 3x more than Carbon.

The method of recharging Purigen can be a hassle and dangerous if not done correctly and potentially threaten to the tank.

Seachem Purigen 250ml: Pet Supplies

Marineland PA0391 Diamond Blend Activated Carbon/Ammonia Neutralizing Crystals, 23-Ounce, 652-Gram: Pet Supplies

For the math 23 ounce of Carbon = 680 ml and for only $9.12
250 ml of Purigen is $13.03.

Cost efficiency vs product usefulness???

They do slightly different things.

I run purigen in my shrimp tank just for piece of mind. I haven't needed to recharge it yet. Every single report of purigen causing a problem after being recharged has to do with rushing the process and NOT following Seachem's directions.

Carbon and purigen are quite different things. Purigen is a godlike substance that will make your water crystal clear, and it's reusable. Probably why it costs more. I don't use carbon in any of my tanks unless I'm removing medication or something like that. A healthy tank doesn't really need carbon.

I've recharged purigen several times, never had a problem.

I guess I'll give Purigen a try, my tank is already crystal clear but doesn't hurt to make it clearer =)

I've used Purigen 24/7 in my planted discus tank for several years, and swear by it's effectiveness as a purifier and water clarifier - I wouldn't be without it.

Re-charging is no problem and not at all risky if you ensure it's well rinsed in de-chlorinated water before using it again after re-generating in 50/50 bleach/water.

You can re-charge every 2 or 3 weeks or so, for up to a dozen or more times, before it begins to lose it's effectiveness (good for a year), so it turns out to be much less expensive than any carbon.

I was wondering... When you guys use purigen, you guys let it soak for a day before putting it in the tank? Or just put it straight in? Im talking with shrimp tanks.

Pretty sure you can recharge carbon unless I'm missing something.

i let it sit in a very heavy solution of de-chlorinator over night then a heavy solution for 8 hours or so before throwing it in my tank.

1 6 gallon
1 2 gallon 8" cube
1 10 gallon endlers tank
1 betta

Here they are http://www.plantedtank.net/forums/al...p?albumid=9625

6 gallon journal

you can see more photos here the 4 8" cubes are on flicker... will get to their journal at some point (they are fun as they change often)
