what if i dont have another tank?? will another bucket work? and what about my filter media or whatever? that has the bacteria and stuff? both buckets are 5 gallons i think. and i think 10 pounds of sand. enough toprolly fill a 10 gallon. i dunno cuz i ahevnt tried.
when you said you did water changes... to get the cloudyness out? do you have to? or will it settle?? is it dirtyness or just it being cloudy cuz its sand?
and also, this tank is kinda new. so, its cleaned out pretty good. the only reason id wanna use the water already in it is cuz i dont have any other dechlorinated water, unles i get that stuff at walmart... i dunno
If you cleaned the sand well enough you should not have to do any water changes...that was just my attempt to "speed" up the process. The sand will settle over time. I would also suggest to get some filter floss, or filter fiber to put in your filter, as that will catch very small particles that have passed through the rest of your filter media. The filter floss/fiber is really cheap, and can be picked up at your LFS as it is pretty popular.
I would assume a bucket would be okay for the fish, granted the water is at the same temp as the water the fish came form in the tank, just swap out your heater and put it into a bucket. I would also try to put the filter on the bucket with the fish, just because it is going to take at least 12 hours for the water to clear enough for fish, that is if you do not do water changes to help speed up the process. The bacteria will dies off at about a rate of 2-10% daily if no ammonia is present. Just do
not let the filter media dry out, as this will kill off your bacteria colony. If you do not want to put the filter on the bucket that would be okay, just keep the filter media wet.
Also, put an aerator in the bucket with the fish. You could if you want, put the aerator under the filter media inside the bucket with the fish. That way no bacteria will die off.
The stuff at walmart? either tetrasafe...I think that is what it is called, or API Stress Coat are good water conditioners to add to the water if you want to swap out the water, and those products are pretty cheap. Anything that says it will take out chlorine and heavy metals will work for a water conditioner, and I would suggest you have them too. So that when you do weekly water changes you can just add that to the new water, and it will be safe to put into the tank.
So I would take the fish out and put them in the bucket...just provide some places for them to hide and what not.
And then exchange the substrate.
Hope this answered your questions?
If you have any more question, do not hesitate to ask.
