i am currently painting my room and i need to move it. i also have a new 90g that is filled with freshwater for the timne being. can i put the fish in it for now until i am done painting or will it trigger the ammonia cycle. their is also no salt in the water yet.
 
it is filled with tap water but i plan on making it a reef aquarium in the short future. will the freshwaters trigger the cycle before i add salt. can i add salt after that with out getting rid of all the water.
 
the heater is running at 78* and the filter has been running for almost a week and the water is perfectly clear now.
 
If you need to move the contents of the first 90g to enable you to paint, empty the freshwater out of the new 90g and move the old water across then the fish rocks ect use new saltwater (i suggest you buy pre mixed as tap water is bad) to make up the small amount you'll lose in the transfer.
If you put sw fish in fw you will kill them!
 
It took over a week to get a stable Sg reading on my 90g after filling it with fresh RO water when i up graded, that amount of salt takes some dissolving.

i was not planning on adding any fish to a freshwater tank but instead moving the cichlids from my 55 to the 90 so i can take apart the 55 to paint behind it.
 
First this is a salt water thread and i think that is where the confusion is coming from. If your 55 is a cichlid tank then yes you should be able to move them to your 90 with fewer problems. But i would siphon the water from the 55 into the 90 then top it off with fresh water also move the filters and any decor from the 55 to the 90. This i fell is better than just plopping the fish into untreated water. I just recently moved my 30 into a 55 and did this and after a few days all my levels where good. I am sure if someone has a better way of doing it they will let us know.
