Can you use just a little bit at a time with water changes or filter changes, then store the rest for later or does it expire?

Hi,That is what I've been doing and I've had no issue. It might eventually expire, but so far I've had no problem! This stuff was a life saver...literally! Lol

I suppose you can use it intermittently with water changes, really shouldn't have any adverse effect, and it's supposed to contain beneficial bacterial for your tank. I used it when initially starting my tank, to expedite my fishless cycle. Though, now, I'd probably recommend using the pre-seeded sponges at angelsplus, versus using the liquid starters. After your tank is established, you really shouldn't need this stuff at all. Your filters will be full of beneficial bacteria.

Short answer: sure. The cleaner the water, the better. But if you're using a pitcher, you may as well filter post-storage.Long answer: My understanding is that water from most municipal water systems is fine being stored with no additional treatment for up to six months. If your water is from a well or other private system, it may vary. If you're concerned about microorganisms, chemically treating your water (bleach, etc) will do the trick. Any other contaminants you're concerned about could be removed with the appropriate filtration either before or after storage. Hope this helps. Short answer: sure. The cleaner the water, the better.

They say it lasts for 6 months, but I change mine every 3-4 months just to be sure. I have good water quality using this product.

Sawyer makes no claims on how long this will last in storage because storage conditions vary so widely. Because it's a filter, not a chemical purifier, it should last almost indefinitely in perfect storage conditions. Even in poor storage conditions with wide temperature variations, moisture, light, etc.... the filter doesn't really break down until the conditions affect the components, which are mostly plastic. That takes a very long time. I don't want to guess on just how long, but if it's unused, I would think a few decades. If it used chemicals that would be different, but it does not so there's nothing but the case and filter which will last many years.

I'm not sure as we use ours regularly but my guess is I would dump the water and refill. I don't think the filters drying out would be a big problem unless they are dirty.

Yep, totally depends on your consumption. Thanks to you I tested the water yesterday and OOPS, I have to change the filter, but we have this filter for at least 7 months

Use half save the rest in a reusable container and you should be good as long as the container is seal

You would just use them periodically, or each time you test. They can not be left in the water for any period of time.

It's my understanding that with proper back flushing and drying the filter will be good for unlimited storage... but hey, for the price, how cheap do we need to be. I have a few that I use on a regular basis and several in "permanent" storage (i.e. go bags). I have reused two of these on a regular basis for well over three months and still feel comfortable with their effectivity. However, I do not filter extremely turbid or dirty water. Such source water I prefilter and let settle before using the straw on them.

Even though it says every 6 months, we don't use it that often so what we do is change the the red and blue filters every 12 months and the purple filter every 24 months (yes 2 years). So far it has not degraded our water quality nor taste. I wouldn't push it more than that though. If you really want to be safe stick with what the manufacturer recommends, every 6 months for the red and blue filters and every year for the purple.

It depends on how soon your scale build up on the filter. I change mine once a month from November to April.

It depends on how much you want to dispense at a time. I personally wouldn't let it go for 30 days without someone checking it.

There is no expiration date on the filters. With two people using the filtered water, mine typically lasts a year. The water flow will slowly decrease noticeably and after a couple weeks will actually stop so have another on hand when it begins to decrease.

We suggest letting the filter dry as much as possible. You can then put in your refrigerator between uses to help prevent any bacterial growth. Place something under the filter in case some residual water drips out.

I purchased extra filters at the time I ordered this product and it's been a couple of months and so far I haven't had to change out the filter. It will very depending on the water and environment but I'm going to say you can at least three months for every filter change would be ideal for you pet.

Not sure, but since the filter is ceramic and they give you some sand paper to clean it. I would say you could use it for a very long time without needing to change it.

I would assume that if you have the prefilter and a chemical filter, you'd be good to go. I can only assume that the chemical portion does not have a shelf life, otherwise they'd have stated so. I've used mine only briefly, and am well satisfied. It's been used where there's a hint of sulfuric acid mist (anodizing) and it has been up to the task.
