water evaporation going crazy

i noticed that my 20 gallon has been losing water like mad. i have checked the whole tank for leaks but nothing turned up. Could it be that my new filters and the new tank are absorbing water or something? or could it just be evaporation? the tank it currently at 79 degrees F.

i know this is probably a silly question however.............
is the lid on properly,the reason i ask this is because
my tiny tank in the kitchen was losing an awful
lot of water and i too thought there was a leak,
until i put the lid on,and the water loss has stopped.

when you set up a new tank,hide an extra
sponge or two behind some decor,that way you have
something seeded for you next filter.

i see you mentioned new filters , the more surface aggitation the more water evaporation occurs . also different filters will cause more evaporation like penguins because of the the extra surface area compared to the volume of water on the biowheel .

a tight fitting lid is a great help and also the difference in temperature from the room to the tank is a big factor .

Do you have a lid for the tank or condensation trays? Without them the tank will surely lose water faster. If you have a lid...it shouldn't be losing so much water....

I'd double check all the filters and hoses/tubes again. Do you have a lot of bubble wands/air stones?

With the changing of the seasons, we normally turn on our home heating systems. Many times this is a dry heat. Air will seek a normal "saturation" point. This means that air of a certain temperature will hold so much water. If you have recently turn up th heat in your home the temp rises, heat usually removes moisture from the air, and replaces that humidity with available moisture--your aquarium water.

Someone has already mentioned that water that is being aggitated evaporates quicker. This is true because the surface tension is broken making evaporation easier. This can be lessened by making sure that your aquarium's lid is tight fitting.

So, to make a long story short, just grab a bucket and fill the tank back up.

i do have one bubble wand and 2 filters going, i just realised the breeder unit for my baby cories is holding the lid open on the front to a certain extent. yes we have turned our heat up,but this started happening b4 we turned it up. i guess i do have lots of water moving, so ill try to fix that.

My 20 high platy tank is down an inch in a week. It's got 2 HOBs and a big bubblewand, and the top is really loose. Plus the humidity in the house is about nil, so I am not surprised.

Logic is only the beginning of wisdom
