Why a weekly 50% WC is better than two weekly 25% WCs

[ScatMan]

your comparison is dishonest.

if cleaning 50% of your horse's bedding 1x a week was enough to keep it happy and healthy, cleaning 25% 2x a week would be slightly worse for him because he would be standing around in slightly more poop on average.

that's a fair comparison.


which is Wrong.... The horse would not get thrush because the filth would never get past a certain point... thats my point. The "average" doesn't matter only the "worst numbers"....

OMG! the "worst numbers" are the same in both scenarios!!!!! how do you not see this???? stop banging your head against the wall and pay attention.

you must have missed my edit: what you're saying is that: 100% wc daily is better than 100% wc weekly, and that i agree with. but it doesn't compare to op's example. do you see how your analogy is completely different than what op is saying?

And calling me a liar for haveing over 20 yrs of animal husbandry experiance is nieve of you. The only thing the OP proved was 1 large water change dilutes NItrates better on a "average" basis then 2x25%... which has nothing to do with the actual husbandry of our animals since other reasons we do the water changes aren't addressed. So His data is incomplete. when it can be proved elevated nitrates won't do harm to our pets then You may call me ill-informed... BTW I was raised that calling someone a lier is hitting below the belt.

what other reasons?

And my point is the "medacine" hasn't stood the test of time to be proven to work, and not do more damage.

The "truth" is better safe then sorry.

I am useing the OP's original numbers for comparison.. so as not to further confuse the debate. so when saying 50% is not better then 25%x2 I'm takeing into account the actual number differences being used. But useing the same numbers the OP threw out there as a grasping point.

keep the gloves up

i'm having a hard time believing that you're not trolling, pardon my low blow.

There's no need to do a water change I had that on my 400g, never did a water change, and nitrates stayed at 10-15ppm. Drip systems with monster tanks is really the only way to go, and lots of people here use that very same system.

That's what I thought.
As for me the drip system is not doable as right now due to the location of my tank. So yeah I still do wc but with no buckets. I call mine semi automatic

THe 25%x2 a week never reaches the same max nitrate levels as the 50% once a week.... omg... open your brain.

dissolved organics, hormones, minerals and vits...? aware of any of these?

If I was trolling I'de have you worked up into a much more aggressive state. and be taking low blows at you. imo the only troll is you. since none of this "math" has shown what impact it has on the fish, only speculations. Your not backing up any of your argument other then throwing the "math" out there. experiances? instances? fish you've kept in this type of UP and Down Nitrate sway?...

holllllllllllllllllllllllllllyyyyy crap!!! YES IT DOES! look at the charts!!!!!!!!!!!!!!!!!!! open your eyes!!!!!!!!!!!!!!! ignoring the facts does not make you correct!!!!!!!!!!!!

dissolved organics, hormones, minerals and vits...? aware of any of these?

the same principal appliies to ALL OF THESE because they are disolved in the water just like nitrate. don't you understand it yet!?!?!?!

the only evidence i submit is the math, you showed nothing, not even math!

Math can show funny unexpected things sometimes. But you can't argue math. It's always true. You can argue application of it. You can argue interpretation. But not the math itself.

If one large WC once a week keeps the nitrate ppm to a lower average according to the math, then it just does. There is no arguing that.

if you can't see how that's possible, remember that you are not starting from the same place with each schedule.

For the 1xpw@50%, you start your WC cycle with 50% old water.
For the 2xpw@25%, you start your WC cycle with 75% old water.

Which fish is living in more filth at the start of the cycle?

lets say you "filth up" 5% of the new water per day.

In the 1xpw@50%, you go 7 days and add 35% for a total of 85% filthy water
In the 2xpw@25%, you go 3.5 days and add 17% for a total of 92% filthy water

Which water is filthier?

Well, it makes sense to me.

Just do 2 WC at 50% per week and don't think about it.

 

[dayak]

Both way will keep the nitrate level in a tolerable amount with the 50% weekly has less average than the counter part.
Unless u like the pain of wasted time more often be my guess, as for me I take that time to admire the fish with my beer on my hand not the bucket.
Those fish waste I know its ugly in the tank but the bad subtance that's harming the fish r pretty much filtered out with ur filteration system so its not valid argument if u take the filter out now we r talking, those bad subtances that harmfull for the fish all r converted to nirates at the ends.
