    I've heard that some say to change 80-90% water change and others have said 50-60%. So whatever it is I'm not sure which one to use. You can comment or simply just vote on the poll and I'll take majority and do that.

    the size of the water change you make after a fishless cycle depends on how hi your nitrates read. If you're only showing 20ppm nitrates, 50 - 60% would be fine. but if you're showing 40 and above, do an 80 - 90 % or even a 100% water change to get them down to to 10 or below.
    Remember - your beneficial bacteria lives in your filter and filter media (and some in the substrate and hardscape) NOT in your water so you can change out 100% of your water and not affect your BB.
    Make sense?

    I just do a 90% pwc. Why bother keeping in too much water if there is no fish in there to stress out? Thats my reasoning anyways

    I always change as much water as I can

    Fish will do their best when they get a lot of fresh clean water
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    I change 50-75% every week. I wasn't able to vote in the poll. Guess I can only do that in chatterbox for some reason.

    I chose "other," because like FM said, it depends on your nitrate level. Sometimes you have to do multiple water changes to get the nitrate level down. Sometimes you only have to do a smaller percentage, because you're already keeping live plants, which consumes the same waste matter that beneficial bacteria eats, so your nitrates are lower.

    When in doubt, ask yourself... W.W.L.S (What would Lee Say)?

    Unsure of why you can't take the poll it should be located at the top of the screen of this post. I was think about only changing 10-20% of the water weekly after the cycle and large water change was complete. I just feel doing that large of a percentage would be a shock to the fish. Thank you for your information.

    It could be, if you were swapping out one ph or temp with another ph or temp. Just be sure to match the temperature of the tank with the temp of the tap. Make sure there's not a big leap in pH from the tap, too. If there's not and the temp is the same, it won't matter how large your water changes are. Just be sure to use Prime.
