1. When doing a water change, does it make a difference in the process

example: man A takes out 4 buckets worth of water, then replaces 4 buckets worth.

Man B takes out a bucket full of water and immediately replaces a bucket full, he repeats this 4 times.

Does it matter?



question #2
I am usualy very good at google searching an so on but am having a hard time with this one. I have very hard water and want to plan the rest of my stock based on species that will thrive in these conditions. can someone point me in the direction of a site or list of fish who prefer hard water. I beleive most African Cichlids do, but I am looking for a community setting...for the moment anyways.

Thanks
 
I think so, because you might be removing some of the new water if you do it the second way. Its really easiest to just empty out what you are going to, then refill :p:
 
Aye, the first way will work out to be a bigger water change overall so you can't save steps by bringing back full buckets after you dump one.

As for fish stocking you should probably test your water to give yourself some solid numbers to look at. That being said given time and proper aclimation you should be able to set up a community tank. I mean if a lfs can keep fish alive then you should be able to.
 
Hound, I do test my water regularly. I do not have the readings in mind or with me but my community tap water and tank water are very hard. I realize fish from my LFS are now accustomed to this but I would love to look into getting a species that would THRIVE in these conditions and maybe see a possiblity of breeding.


edit- THANKS YOFISHBOY!!! I owe you one :bowing:

By hardness I trust you are referring to GH and not pH, correct?

The article that YoFishBoy linked to was pretty good, but it would be nice if he actually explained the different between the two.

Also, he is incorrect on rainbow fish. He's generalized them as hardwater fishes and you can't really do that. Most rainbowfish come from many different types of water -- even within the same species. My Boesemani come from a hard water region and they are readily spawning in my soft water. Most Rainbows aren't picky.

The 'remove all, replace all' is far more effective than the 'remove and replace then repeat' process. It is a dilution and mixing issue.

Most tropicals do not care particularly about water parameters for maintenance without breeding. Some particular fish have water demands at breeding but that is for the eggs not the fish. Some blackwater fish have better color in soft acid water or in water with a bit of tannin, but if you do not have them in side-by-side tanks you are unlikely to be able to tell.
