Memorial Day Perking Up!

Memorial Day is for remembering our loved ones fallen in combat in our nation's conflicts and also those who have served in the armed forces, especially those sent in harms way. They used to plant tree, still do I expect, to honor and remember.
I thought I'd put up a picture of the float system today. As you can see if you compare this picture with the one from a couple of posts ago, the plants have grown a bit. I'm still running the system at a CF=19. The next time I fool with it I'll take it up to about 22 or so. There are two pumps in the system. One is driving the central fountain which is there to cause water to drop into the pool and oxygenate the water. The other is just circulating the water to keep it moving. So far it is working well.
