How often do I have to replace carbon filter for a 2.5 gal tank for 1 betta fish? I plan to replace it when it is needed opening the tiny case.

I only needed to replace mine at most, once a month. I would say it really depends on if you leave the filter on when you feed your fish. By turning it off during feeding, I could sometimes go 2-3 months before changing it.

Once a month would be more than enough. Carbon is not necessary in your set up, but it would give the water a more polished look between water changes. Carbon left in place too long can actually start to release contaminants back into the tank. I would change half the water in your tank once per week, cleaning the filter every other time, and the carbon replaced every fourth time.

The prefilter is there to catch sediment before the water passes through the carbon filters. This prevents the carbon from getting clogged up prematurely, extending the life of the unit. We recommend replacing the prefilter cartridge at least every 3 months. Actual interval will depend on your incoming water quality.

My water is very good, low in minerals and things that would affect taste so I change them every 2 months. I do back flush the container to clean out debris at least weekly. I also found it worthwhile to dispose of the smaller charcoal pieces that will clog the end caps.

You will need replacement filters, it comes with one. You will need to change the filter at least monthly, or depending on size of tank and number of fish. I have a 2.5 gallon tank and four small fish. I do a partial water change monthly. Once in a while, if needed, I take the filter out and rinse it out and put it back. But at least monthly put a new filter in.

When I initally bought my "big" setup, I read that you should replace them once a year or max 1000 gallons. I replaced mine at the one year mark. If I were you though, I would order directly from propur. The customer service beats the other retailers. And by the way, im skeptical that these filters actually filter out flouride. Do your research

I've only had mine (two in two tanks) for a few months so it's too early for me to report from personal experience if/when they need replacing, but the company says they last 1-1/2 to 2 years. Actually, I don't know why they'd ever need to be replaced, as the bacteria should regenerate, although the stones are supposed to leach calcium and trace minerals into the aquarium, and that effect would eventually diminish. Then again, I don't know why they should do anything at all for a biologically filtered aquarium that gets frequent water changes, but they seem to have improved water conditions, even in a couple of tanks that were in pretty good shape to begin with. I may add them to some other tanks eventually.

I've seen this as well. Killed off a few fish before I stopped using the aquarium. However, it was the filter that came with the aquarium, not a replacement.

I would most likely say 1-2 weeks, and then you'll have to clean the filter out. This filter only cleans the water of little particles. This filter does not clean up the feces on the bottom of your tank. I like this filter a lot. I have three baby bettas in a 5 gallon and this filter keeps the water clean for 4 weeks. Hope this helps!

The water will need to be changed once a month about 25% of the water. The filters last quite a while because the filter system is actually designed for a 5 gallon aquarium. Once you notice the filter over filling that's when you change it

The problem is that carbon filters provide a warm moist environment to grow bacteria so you pobably want to change them every 3 to 4 months. S.Chiples

Hi Edward, I have the big filter series that take two filters. I use it for a fifty gallon rubbr stock tank I keep in the basement to keep giant goldfish brought in from the winter. I keeps the tank clean as there are 8 really big goldfish. I usually pull out the two filters about every three weeks or so. I also take out the whole unit and clean out the scum from the unit, So-- 3 into 52 weeks in a year-- 17 or 18 times. These are messy fish, so maybe I change them more often than I need. Hope that helps.

I also use this for a red eared slider turtle. All of the filter media I change at different times to allow the "good" bacteria a chance to do their jobs and not "shock" the water with all new stuff. The carbon I like to change at least every 4 months. The polishing pads if you use them I change every month and the foam filters I will rinse every month or so, but change out with the carbon every 4 months along with the carbon.This is a great filter system! Let me know if you have any other questions and I hope you found this helpful!

hi, i would be happy to answer your question the box says 25 gallons but we have used ours for at least 50 to 70 gallons the minerals might be gone but the carbon is still there giving the water a great taste i do not know if you have yet but the filter is very imprtant for taste becuase if dont have the water taste kinda likeplastic at first becuase the vapor picks up the smell of the new plasic but the carbon filter completly eliminates this all in all great product even bought relitive one. filters are about 35-40 for 2 pack.

A properly cycled tank should NEVER get a FULL water change. Once a week change 25% (50% when necessary)of the water with a gravel vaccuum and add a biological supplement like API Quick Start by pouring it over the filter. Change carbon every 4 weeks, biomax at 6 months, and foam at one year. Rinse Bio and foam (not at the same time) every 6 weeks when changing water.

Very Easy.... and a huge savings instead of buying the packs of only like 3 pre-assembled. The blue frame is reusable. Slide frame into filter, pour in 1 pack of the carbon, clip the flaps of frame down to close the filter, rinse under cool water to remove any carbon dust then put into fish tank filter unit. That is all. Takes me about 30 seconds.

Basically I ml per gallon. So if your tank is over 100 gallons get two. If under 100 gallons use one. I have a 29 gal tank and use one bag. I recharge about every 3 months. Tbe beads never turn black but more of a red brown color. I will rinse it under fresh water each time I do a water change. If you do not already have Prime, buy that as well. You should also be using rodi water. I bought my filter from bulk reef supply.

Everything that is needed to start filtering is included. Only things that are not included is the filter media, bio balls, etc. It all depends on the type of aquarium you are trying to set up (fresh water vs salt water). I run GFO in mine for my reef tank. Carbon is useful in just about any aquarium. If you do use a filter media, I would suggest buying filter bags as well, or else it will be spread through out the filter, caught in the filter floss, and wasted when you clean the filter weekly. Most medias last more than 2 weeks, so you want the ability to take the media you are using out and put it back in after you are finished cleaning. Or else you will have to replace the media, which wasn't fully used. Even with out the above materials, the added flow and filter floss will help in over all tank health.
