    Im doing mine now (12% or so) just thinking how everyone did theres. Im 3x a week on mine:

    10-15% tuesday
    Same thursday

    20-25 % saturdays

    Whats your way of change?

    Once a week, on Thursday. I usually take out around 25%, but probably a little more than that sometimes lol!

    25-30% on Sundays. Is there a reason you are doing them that often?

  4. LeoDiaz Fishlore VIP Member

    Same lol but i do more around 40-45%

    I do 40-50% weekly on my tanks

    Three times a week does seem a bit excessive... I do 25-40% on Saturday mornings.

    Once every 10-14 days. 50%. Siphon out the patio door, python to fill it.

    I usually do 20-30 percent weekly.

    If I get busy and do a biweekly I'll do about 30-40.

    I was doing 50% a week but now that I have so many plants and my nitrates are barely rising I am going to once every two weeks. I do use polyfilter to absorb organics also and R/O re-mineralized for top offs.

    See that's the problem I'm having, as you can see in my Flourish Nitrogen thread.

    My tap has 5.0ppm nitrates so at least my top offs feed the plants :)
    But its been 9 days since I did my water change and my tank is at 7.5ppm nitrates, which I'm thrilled about and was the whole point of planting the tank in addition to enjoyment. But trying to figure out the right schedule for health of the fish. I know the plants overall make the tank much healthier and I'm adding in back in replenish for calcium/magnesium. Interestingly enough I tested my alkalinity today and it has dropped about 40ppm from 180 or so down to 140. Maybe I'll be putting some crushed coral in my tank too if I'm doing less water changes! My ph has remained high though. Normally about 8.4, right now 8.2.

    I would like to limit water changes to twice a week also but wouldn't if it affected the fishes health negatively. How does Walstad maintain the minerals in her method, or does she use stuff like Replenish?

    I read her book but don't remember. My guess is she used a layer of argonite or something in there. She only did water changes like once every 6 months but it was a very particular eco system where the plants out numbered fish and their bio load to a pretty big extent. She didn't use any additives like fertilizers either. She felt the decomposing fish waste was enough.

    I was use to a really overstocked where i did it 3x a week..i just kept the habit
  17. leftswerve Well Known Member Member

    Currently at 2x20% a week. I do it in two intervals because 3 5g buckets of water is enough to carry at one time.
    I also do it twice to control nitrates, I'm working on other methods (more plants and denitrate filter). Yes, I overfeed, i deal with it (so does my tank)

    Once a week, 75%, using a Python Clean-n-Fill to drain. I have a 60 gallon vessel that I fill beforehand, and use that to refill the tanks. If that runs out I use plain tap water to refill. I do tend to feed heavily, so this works for me. I use sodium thiosulphate to eliminate chlorine.
