Bleaching bottom up

[sgtbilko]

I have two acros bleaching from the bottom up. There each about 1/2 bleached. I cant figure out why.

Nothing bad tested.
calcium 480
alk 8

water changes every 2 to 3 weeks.

Lots of love given to the tank.

Just cant figure out why im getting bleaching from the bottom up.

Anyone have any thoughts.

and how about a photo or two
