Moving Fish

hi guys,  has anyone got any advice on moving a fish tank..  i am moving my 30l tanks with 6 fish in( 4 x platys and 2 cardinals ) to my daughters for 3 weeks while I'm away, its about 20mins away and wondered if anyone has done this and which is the best way to keep the stress down on my fish,  thanks

30 litre tanks shouldn't be a problem. Just fill a bucket with tank water, put your fish and filter in that then empty the rest of the water away. At the other end, put warm dechlorinated tapwater in the tank, and add the water, fish and filter from the bucket.
The thing to note is that tanks must be empty of water when they are moved. Water, even an inch, will slosh around and the tank seals aren't designed to cope with that sort of movement.

If the water at your daughter's house is somewhat different from yours, take more tank water so you don't have to add much of her tap water.

Sorry, read your post as 30 gals. Probably best to wait. Good luck with the move
