I realize every tank is different, but approximately how long does purigen last before having to recharge?

I have one in a 30 gallon tropical tank. The tank has a very large piece of driftwood which leaches some color into the water. Purigen keeps the water absolutely clear for about a month. I keep two bags. One in the filter, and the other regenerating and then in storage for a month. Love this stuff!

You will tell when it all goes brown. I have mine in a 20g long and it lasted about 4 months.

I bought 2 of these. One lasted 4 months the other 6 months in aquariums. I would guess you might get a good week or 2 in a cold sump before it stops working.

I would recommend every 3 months. Make sure you use chem pure elite. The forum seem to say it works better. They also use purigen 100. I have a 34 gallon. Reef sanctuary is a great forum to learn about tanks. I am also running a reef set up.

If concerned you can back flush the tank before each use and recharge with salt. The manufacturer recommends back flushing every 6 months. Clean water sitting in the tank should not be a real issue for 20 days.

It really depends on the length of the burst that you use. We tend to use a two or three second burst every five minutes, and the tank lasts a LONG time. We have been running it for several hours every other weekend for the past several months, and it's just now below half full...

4-5 days in my experience, but we usually drink it the day we charge it. It might last longer if there is more water in it.

It often depends on how clean your filters are. Our water has a lot of minerals in it. I change my filters every 3 weeks. A full tank with clean filters lasts about 12 hours. With dirty filters, the tank never empties properly. The water can't get through the clogged filters. I always run my humidifier on high, and I keep my humidifier clean. Breathing for me is always easier with properly humidified air.

Mine usually runs for 10-12 before I refill it. It's going to depend on the level of saturation you put it to.

More than 3-4 hours. Havnt tested it for that but distilled water is super cheap to buy so isn't a concern.

I recharge mine when it turns brown like weak tea color. 1 should be enough depending on the biological load. If you have protein skimmer it should last 4-6 months between recharging

I have not actually tried to time our usage so cannot put any real number on how long the 5 gallon (20 pound) tank lasts. Having said that I have not felt that tank went dry quickly.

Not long, 2 or 3 months at the VERY longest. This is a trait of the NiMH batteries, NOT the brand. Personally, I would top-off any battery I was planing to use during an electricity free vacation, no earlier than a week beforehand, in order to have the most juice on hand when you need it. This is from my personal experience with a wide selection of brands and a wide variety of battery ages. Everready, on the other hand, claims that NiMH batteries in general will loose 50% of their charge in six months. I expect this may be the case under the very best laboratory, tempature and humidity controlled conditions. Not under normal conditions, like your camera case, electronics drawer, or your battery shoe box. Now... While I've never seen a STORED NiMH battery hold a charge that long, I HAVE found that using them in something that draws a small, but constant current, will give you a MUCH longer shelf-life than charging them and then storing them. Depending on what they are in, I've seen them last up to a year or longer.

I'm not sure exactly but I have used mine for several hours and still have almost a full tank.

I have only used mine for about two hours total so far, for melting lead, and used less than a quater of a 20 pound tank according to my tank scale. So a full tank should last arround 8 hours.

3 to 3 1/2 weeks you might want to buy better battery.works great in the refrigerator have 2 running and you can tell a differents in the food ,freshness of my refrigerator. Good investment.

A E Tank holds around 680 ltrs. of oxygen. So a tank will last around 25 mins. at 25 lpm. here is how I came up with that, tank ltrs. / lpm. / 60 = time. I hope this helps you

The battery life is fair. The tank can run for about 30-45 mins before the battery is drained.
