Here's a quick update. In order to get ready for the new pump for the under sand filter I had to switch the current pump over to a spray bar. I used 3/4" pvc and drilled it every inch with an 11/64" drill bit.
I also built the drain portion of the closed loop. Wanted to go ahead and get all of the pieces that needed painted taken care of.
Then I applied a little paint.
And wahlah...
A little full tank shot.
I am really impressed with the amount of flow the spray bar is creating. I think I am really going to be happy with the circulation once I get the new pump hooked up.
Oh, just for the heck of it, here's a crappy picture of one of my favorite fish.
