    Ii thought I would write the cycling journey with my Betta here.

    After setting up the 5 gallon tank, I put media from my cycled tank in the filter. The filter is from a Tetra kit, a Whisper. It has really low flow, but Bettas aren’t good swimmers so it’s okay. Since I removed the original carbon cartridge and replaced it with my seeded media though, the flow is even less so I’m thinking I might have put too much for this weak filter capacity.

    I’ve seen a video from someone who used this filter for many years with the tank, also for a Betta, so I will be more patient before deciding this filter isn’t doing a good job.

    On day 2 :
    Ammonia : 0
    Nitrites : 0
    Nitrates : about 10-15 ppm
    (For the first time I had filled the tank my my cycled tank’s water, which had just had a water change, thus nitrates at that level).

    I did not test on day 3 (but will be testing daily for a while).

    On day 4 (today) :
    Ammonia : 0,25
    Nitrites : 1.0
    Nitrates : between 10 ppm
    PH : 6,8

    On day 4 after 70% water change :
    Ammonia : 0
    Nitrites : 0,25
    Nitrates : 5 ppm
    PH : 7,2

    Yesterday Charlie was lying in bed more. Today he is more active. Since I don’t know his habits much, I thought he was a little lazy. But the water quality must have been the cause.

    I looked at my parameters from when I was cycling my 45 gallons (also fish-in), and it appears that with this 5 gallon, on day 4, I am where the 45 gallons was on day 20 (nitrite peak). The 45 was cycled on day 26.

    So, I’m hoping the 5 gallon will be fully cycled in about 6 days. If it is, it will have taken 10 days, thanks to seeding, instead of 26. And it started almost at the nitrite peak point.

    Until then, I will do many water changes, as many as necessary. I will do another one tonight so Charlie has a good night. And tomorrow, and so forth.

    Water changes with a 5 gallon are such a breeze, especially since the tank is close to my sink, lol !

    That is the beauty of having a cycled tank. Almost instantly cycling another tank is a breeze. I keep 2 dual sponge filters running in my main tank. Any time I need to set up another tank just move one of the seeded sponge filters to the new tank and it instantly cycles it.

    How quickly it cycles depends a lot on the bio-load of the tank the media is moved from. If it comes from a well stocked tank there will be a lot of bacteria on it. If it is coming from a tank with just one or 2 fish there will be less and it won't instantly cycle a tank enough to handle the bio-load of more than one or 2 little fish but will still help.

    My cycled tank is still lightly stocked for a 45 gallons : 3 rosy tetras, 1 serpae, 3 platies, 1 SAE, 1 oto and 2 cories. My nitrates are a little too high for my taste so I am waiting until I get them where I like before adding more bio-load.

    It’s great that you always have media ready for the next tank. I guess you must have many. This one will be my last, not enough room.

    Parameters tonight after 40% WC

    Ammonia : 0
    Nitrites : approx. 0.12-0.15 ppm

    Today around noon :
    Ammonia : 0.25
    Nitrites : 0.5

    I did a 65% water change and increased the filter’s flow to help cycle faster. Charlie wasn’t fond of the agitation so I try to find a common ground. I can’t go any lower but he is still not sleeping in his bed (I put it on the other side so it would be farther away from the filter, but nah, he’s not happy. Not much I can do for now).

    After water change :
    Ammonia : 0.1
    Nitrites : 0

    Around 6 pm (no change) :
    Ammonia : 0.1
    Nitrites , 0

    Today at 1200
    Ammonia : 0.5
    Nitrites : 0.25
    PH : 6.8

    After 65% WC
    Ammonia : 0.1
    Nitrites : 0

    I increased water flow from the filter, as the cycle seems to need it. Charlie B will have to get used to it.

    At 6 pm (unchanged)
    Ammonia : 0.1
    Nitrites : 0

    Today :

    Ammonia : 0.35 ppm
    Nitrites : 0.15 ppm

    WC : 50%

    I’m glad to see the ammonia decreasing and nitrites starting.

    I took some overgrown plants from my 45g and put it in with Charlie B.

    I'm not sure how I missed this post. I truly was not ignoring you.

    I don't really have that many. I have my main tank-the 55 gallon. I also have a 10 gallon, a 5.5 gallon, a 2.5 gallon bowl with plants and one nerite snail, a 2.5 gallon jar that is my snail breeding jar and then just today I set up a sterlite storage container that holds about 3 gallons that I am hoping my BN pleco eggs will hatch in.

    With that many fish in your 45 gallon tank there should be lots of bacteria on the media so it should work very well to seed another tank. Actually I am surprised to see that you have gotten ammonia and nitrites in the betta tank. I would have expected it to have instantly cycled.

    (I see I got my posts mixed from 2 different threads, lol!)

    It’s the first time I’m doing this, but I am also a little surprise it’s taking so long. Today is day 10 or 11 and I still have ammonia and nitrites. I didn’t have any the first few days, maybe because I was using my other tank’s water.

    I actually wouldn't use water from another tank. In my humble opinion fresh clean water would be much better for your little guy.

    I agree, I only did it for the first two days (after my other tank had a water change), to help with seeding. Since then Charlie B has been getting fresh water from at least 50% WC every day.

    Today (day 16 I think)

    Ammonia : 0 (yeahhhhh !)
    Nitrites : 1.0 ppm

    Water change : 50%

    It looks like it will take close to as many days as with my non-seeded fish-in cycle (26 days).

    I suppose the flow lf this filter is sooooo low that it’s not enough to do a good job at spreading the bacteria, so it’s going very slow.

    But we’ll get there, I’m sure ! :)

    Day 17 :

    Ammonia : really 0 now ! (there must have been a tiny little bit left yesterday, as the color is even more yellow today)
    Nitrites : 1.0

    WC : 50%

    I have seen « long » detritus worms today, they really gross me out. I’ll start feeding pellets only so there is no food falling on the bottom.

    Day 18

    Ammonia : 0
    Nitrites : 0.5

    WC : 50%

    We’re making progress, the nitrites have started going down. When they’re at 0, I’ll check the nitrates. Or maybe tomorrow, we’ll see.

    Hopefully 3 days to go, maybe 4 !

    Lots of times when the nitrites start doing down they drop to zero quickly. It looks like you are almost there.
