Too many water changes? Is it possible?

[ercnan]

what about the fact that tap water contains things like chlorine, and floride?

what about places where water is hard or not perfect for fish perams?

i think all these things needs to be considered.

and don't forget the temp difference. is your tap water colder/ hotter than whats in the tank?

your temp drasticly drops a couple degrees cause of rapid water lost replaced by colder tap water? now think how the fish would feel.

and also how come no one asked how big the tank was?

Like a nice rain shower?

How much do you think the temperature of the lake drops when it rains?

Large Water changes are good if they are done frequently. If your tap water parameters match your tank parameters, and your hot water heater can handle it, then you should be ok.

Large water changes after a long period of time can cause sudden shifts in pH balance and the level of dissolved solids in the tank, which effect the fish's ability to osmoregulate.

Different water change schedules for different types of tanks. My overstocked community and cichlid tanks get large water changes often. My planted, soft-water tetra tanks get small water changes every once in a while.

It just depends on each individual scenario.

What about when it floods, it would be a considerable ammount I would imagine, and then there is usually a breeding frenzy.

there was an article about keeping oscars, and the guy put like 12 in a 75 gallon tank and did 100% wc's daily, and had another oscar in a 300 gallon with weekly changes, and the ones in the 75 were much healthier, grew faster, and they would even go right in the stream of the buckets of fresh water being poured into the tank.

Got a link to that article.

no fish likes aged water. http://www.theoscarspot.com/index.php?option=com_smf&Itemid=49&topic=4894.0
that proves it they live wild with 100% or more daily water changes.

Got a link to that article.

Here is a link, ya have to scroll about half way down the page.

My bad, didn't notice that there. Thanks for pointing it out.

Quite true. But that's fish taking advantage of a particular environmental effect to their advantage. They're not doing it simply because they feel really nice because of all that lovel flood water. They breed when it's best to begin the process of finding a mate and begining the process of raising fry.

It's all about future practicalities not because it feels good.
Fish aren't like women who like the perfect setting in terms of roaring fires and candles before engaging in lovemaking, fish spawn when they need to.

But if the fish are suffering from shock due to the sudden drop in temperture then they wont breed, they are stimulate by the rising waters. It is how they have breed over generation, getting use to the sudden temperture change, they can also get use to 50% daily water changes as well.

Also it depends on your standard of woman to how you need to wow them, some need only payment and a dark ally.

A lot of animals of course breed as a last ditch attempt to distribute their genetic information before death. Still others kill themselves in the breeding process.

Driven by the reproductive desire fish and many creatures will tolerate fantastic difficulties but they wouldn't be happy living through that everyday.

It's not like us sensible people who wait until we can provide a good stable home and have a happy domestic life before we mess it all up by introducing screaming infants

My silly analogy aside, I’d agree with your statement to the effect that some species are clearly more tolerant of environmental change. Different species do have different tolerances depending on whether they have evolved to exist under dynamically changing conditions or very stable ones.

The object should be to ensure we know which fish are better adapted to a more variable environment before hitting them with enormous percentage bulk water changes.
