I use it for my 2 10g tanks and my method works well. Just make sure the hoses are all nice and neat and just place gently on the top of the water. it will fill up and youre set. If you dont have the tubes nice and neat you'll end up making a mess when you go to reach the end to the bucket. Trust me...been there and done that!

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
