Once to twice a week if you have no filter or if you don't but any conditioners. If you do have a conditioner or filter follow its instructions.

When is the best time to clean a fish tank?

The best time to clean a fish tank is time that is available to you every week for maintenance.It's a good idea to set aside time one day each week (preferably the same day so you never forget) to do at least a 50% water change, and to clean any debris or waste from the tank.


How much water should you leave for the fish when you are clean the tank?

The general rule is that one should change around 25% of the water at a time, thus all you need do is leave your fish in the tank and siphon out 25% of the water, and then replace with dechlorinated water of the same temperature. If you are cleaning a bowl, then it is more common to clean the entire bowl; in that case the fish maybe be placed in a bucket or cup.

Do you let new water sit before you put it in the fish tank?

I do. My belief is that adding any kind of chemical to the water in a tank is basically the same as adding chemicals to the air I breath. I would not appreciate it. All I need is clean air and all fish need is clean water. The chlorine added to reticulated systems will evaporate off given time, so I let top up water wait overnight in buckets before using it.

Well, you dont have to put anything inside daily just put a little bit of Tap Water Conditioner every time you wash the fish tank with tap water. If its a big fish tank do wash it every week and if its small wash it every three days.
