No water changes ever!!

This is a discussion on No water changes ever!! within the DIY Aquarium forums, part of the TFK Resources category; --> Good idea, I will definitely give it a try. I was lost on the idea, but watching the video helps....

i'm skipping ahead

if the top of the drain bucket is above the water line, it will never overfill,

when the freshwater bucket is empty, there is all the water possible that has gone into the tank
excess being moved into the drain bucket
... lets say there's a major discrepancy one way or another, dono, don't care.

once the drain bucket filled till it's water line was on par with the display tank it will not drain any more.

the only issue is if the line plugs up or gets pinched going to the drain tank.

then you've got 5 gallons of water going into a tank that has no ability to drain off the excess, ... if your water level is low enough to handle an extra 5 gallons, your doing fine.

no leaks no mess, could have total mechanical failure for either bucket or display tank, ... and no excess water to pool up on the floor

reading through the thread more now

regadless of peoples complains about if it counts as weater changes and nitrates building at a faster rate than the water is moving ...

-5 gallons a day
-gradual through the hours it takes, so no matter how extreme the difference is between the water in and the tank there is no stress
-there is zero time spent changing the water only changing the buckets

how many people do weekly water changes at 20% of their tank ?, even 50% of their tank

5 gallons a day for 7 days = 35 gallons of water changed in a week
20% = 200 gallon tank
50% = 70 gallon tank
math off the top of my head

lugging 35 gallons of water back and forth in a single day is a lot of work
i say kudo's to this idea, ... requires more space, but the effort is greatly reduced to how often your vacuuming the gravel (and occasional air/water lines plugging up)

Those that don't use a water changer use buckets to change their water....

Have you heard of a water changer? If I had to lug buckets I wouldn't have my tanks.

I'm one of those weird people who actually enjoy changing water. And I lug buckets to do it.
As the water is siphoning out, I visualize all the crap and harmful compounds leaving my tanks, then as I add fresh tapwater, I think of it as fresh air entering a house that has been closed up for too long. Maybe its jist my overly fertile imagination, but it always seems like my fish are much more active and hungry after a nice water change. I can ALMOST hear them saying " thank you, daddy for the fresh water!"
Plus I like to.use the waste water for my garden.
I'm sure that as I continue to age, I'll eventually become unable or unwilling to struggle with the 40# buckets of water, but for now its a labor of love... no automatic waterchangers for me, not yet anyway!
Very nice idea though. It could be perfect for some people. I use 10 five gallon buckets to change all my tanks, probaly a huge challenge for many fishkeepers.

how many people do weekly water changes at 20% of their tank ?, even 50% of their tank

5 gallons a day for 7 days = 35 gallons of water changed in a week
20% = 200 gallon tank
50% = 70 gallon tank
math off the top of my head
More people do 50% weekly water changes then your probably aware of and for good reasons. Multiple water changes(daily or weekly) do not have an affect that is direct to their sum. Simply put you do two 50% water changes, the next effect is 75% of the original water is changed.

35 gallons weekly
17.5% = 200g tank
50% = 70g tank

5g daily for 7 days, the overall effect is
16.2%=200g
40.5% = 70g

However the effect of controlling wastes is more disproportionate then this lets on, tho the degree varies depending on the variables. Lets say your tap water has 5ppm NO3 and your tank is stock in a way that the bioload produces approx. 20ppm NO3 per week(heavily stocked).

In comparison to 35g weekly:
-70g tank- Over one week of daily 5g water changes NO3 levels will be 33.5% higher.
- Over two weeks of daily 5g water changes NO3 levels will be 44.9% higher.
-200g tank- Over one week of daily 5g water changes NO3 levels will be 7.4% higher.
- Over two weeks of daily 5g water changes NO3 levels will be 8.9% higher.

You can certainly have nitrate build up faster then water is changed especially with the daily water changes given how this works and dependent on all the variables. No method works the same for every tank. Tank size, water changed, tap NO3, and estimated NO3 production are all variables here. The overall basic understanding is that multiple small water changes are not equivalent to the same volume single change. However understanding the % difference between these two methods will usually be smaller then the % increase in nitrates levels. This I have always been confident about just haven't ever bothered calculating it out. I had to seek help in calculating this and verifying that its (probably)correct and it only involved cookies, headaches, drugs, and murderous urges. On the bright side I have a pretty awesome excel spreadsheet now.

Additional comparisons using 5ppm tap NO3 and approx 20ppm weekly NO3 production(regardless of tank size).
50% weekly water changes: nitrate will stabilize at about week 6 with 45ppm before a water change and 25ppm after a water change
25% weekly water changes: nitrate will stabilize at about week 15 with 84ppm before a water change and 64 ppm after a water change
Nitrate will always level out... eventually... given the math. The smaller the change the longer it will take and the higher the value at which it levels out.

Also those carrying buckets are crazy, the hose was invented for a reason. 1/2" vinyl costs like 25cents a foot. Also the few minutes of dragging a hose around and doing things while it drains/fills counts as changing water, just like changing buckets counts too.

Large water changes will not stress fish given they are fairly regular and your not changing source waters. Only temp and TDS really have the ability to stress/shock fish, and you still have considerable wiggle room there.

Mikaila, thanks for the math :)

i knew there was a difference that didn't quite add up, i just went with "it's gotta be close enough" so left it at that.
but yes, daily changes vs. weekly are going to be less effective, ... but daily changes of 5gallons is so much easier than 35 gallons once a week having that all at once

Not really. Bucket users are already doing it the hardest way possible. Daily water changes simply spread out the work load but the net effect is less.

For those of us that believe in hoses the difference is an additional 5-20 min of sitting on the couch drinking. The physical labor of moving the hose is the same regardless how much you change. The more you change just adds additional time to gravity emptying the tank and water pressure or a pump filling it.

Srsly the whole idea of daily water changes being less work is only true to those that do it in the way that requires the most work, then complain that its a lot of work....

I was changing water while I wrote that.

Amen.

I change 80% when I change the water. Why? Because I can. I take it one step farther and throw a pump (firmly believe in pumps) on the end of the hose to further expedite the process. Too, that allows me to drain one tank while filling another. It's about working smarter, not harder. But some people like doing things the hard way and that's fine - we all get different things out of the hobby.

i'm not a bucket changer, ... one of those people that doesn't change water, just replaces evaporated water, ...

but i do use a bucket, i fill it with water, i have an air stone in it so it doesn't go stale. or whatever the truth behind it is, ... i believe it does it's part to gas off chlorine. the reality may be different, oh well.
