That's a temp setup untill I get my refugium set up and redo the whole return piping. It will be necked down to four 3/4" outlets across the tank. (with siphon holes)

Thanks for asking, and yes, I like the orange sponge also. I hope to get a couple more and some type of fans.
Glad to hear you have stuff in place and future plans....no fun to come home to more water on your living room floor than what is suppose to be in your tank!!

If you do the piping yourself...angle the holes so that they are facing different directions. Adds a nice touch to the return.
