i know it's not a good thing but never found out the reason. anyone care to share why 100% water changes are a bad idea? i know because it'll remove bb, have a great pH/temp change and the little details, but anyone have good explanations? thanks in advance!
 
Where are your fish going to go if you change 100% of the water? Are you just going to let them flop in the bottom of the tank until you fill it back up?

Aside from that, you can shock your fish by changing all the water. Unless the water your are putting in the tank has the same parameters as the water you're taking out, you run the risk of shocking your fish. This can be caused by temp spike/drop, pH spike/drop, so on and so on.
 
why would you want to do 100% of water change? is it necessary?

draining out all the water from your tank and refilled it is like recycling your tank over again. your water parameter won't be the same and your fish will get sick for sure.
 
It's like sucking out all the air of your house, filling it with water, and then filling it with pure oxygen. After about an hour, it should be back to normal, so don't worry.
 
hey guys, i KNOW it's bad for the fish due to pH/temp changes etc. i was just wondering what the DETAILS were. anyone?

your answer is in the question....

fish are very sensitive to temperature change, a sudden change in temperature is very bad and can kill fish
 
Exactly what DETAILS are you looking for here?

hmm, i was hoping there'd be an explanation as to why the fish cant stand the sudden pH, temp and uhm....water change. a down to detail biological answer as to what happens to the body when the water is completely changed.:D

im not that dumb c'mon guys i know a 100%WC is bad:)
