Do you agree with this extreme water change practice?
I read an article that discusses how to reduce toxic levels of ammonia/nitrite/nitrate quickly (in an already cycled, established tank).
Basically, you siphon out 80% of the tank water, then add 20% of the new water. Again, you siphon out 20% of the tank water and add 20% of the new water. Finally, you siphon out 20% of the tank water and add 80% new water. Good idea? Bad idea?

bad idea. The microscopic goodies on the rocks and such that will be uncovered for the long duration might die off and then you will have a nice cycle. It also seems really unnecessary, think of all the wasted water and salt.
I wouldn't think of doing such a large water change to begin with. Im doing weekly 10% changes and after the cycle I haven't seen a hint of nitrates. |

in order to keep them alive you would only have to splash them with water periodically

i'd say bad idea too, but if you need to change the water QUICK then it would work the best i think.

I would only do that if I absolutely had to.

If you're exposing live rock... bad idea. If you have levels of ammonia, nitrate, or anything else that require that much concern... shame on you.
Sounds like they're descibing what to do with an abused tank to try to save it. Don't abuse your tank and you should never have to do this. |

I agree with most of what was said here.
However, IMO this would be a good way to handle things if you had a massive spike in ammonia due to something big dying or some other toxic release into the water column. I lost an anemone to a heater a while back and had to do something similar. Not quite as extreme, but it was at least a 75% water change by the time I was done. I read up on anemones darn quick after that episode.

No way do I agree with that nor should you consider such extreme water changes unless it's a crash cituation. Just my opinion though.
