Great tank!

Your going to like having a big ol tank like that.
Not trying to be a pain in the neck, but it would help GREATLY if you were to extend your intake tubes all the way to the bottom of the tank. Debris, poo and uneaten food tend to settle at the bottom and having the intakes right at the bottom allows the filters to do a much more efficient job.

You can extend them by purchasing a few lengths of vinyl tubing from your local home improvment center. Should be more than a couple dollars at max. Just measure the outter diameter of the tubing that is on the filter and purchase the lengths of vinyl with an inner diameter one size smaller.
If the intakes are 3/4
outter diameter, then buy 5/8 [B]inner diameter vinyl tubing.
Then, just push the new tubing over the intake and the intake extension until you have the screen part of the intake right at the bottom.
This REALLY helps keep your water sparkiling clean......
good luck!
