That thing is HUMONGOUS! Now only if I can find one for a decent price. Well come on... we're waiting for you to hook it up to the skimmer.

I got my new mesh needle wheel today, but am unsure as to how to remove the old one. Could somebody please help? Thank you.

Since a lot of the Reeflo owners may have not torn apart a Sequence pump before, I figured I'd document the process quick as I was upgrading mine. It isn't as easy as a smaller pump, but it's not overly difficult either.
Two images of the needlewheels (original left, Reef Specialty on the right).

Step 1: Obviously drain the skimmer and remove the pump.
Step 2: Remove the six nuts

Step 3: The end will come off

Step 4: Get a large flathead screwdriver. The shaft of the pump extends from inside the stock needlewheel all the way out the back side of the pump. Insert a screwdriver into the slot (which will hold the shaft in place), and unscrew the old needlewheel.

Step 5: If your new unit doesn't have the middle seal, move it to the new unit. This is one of the sealing mechanisms that allows the shaft to extend from the wet section here, through the air gap, and into the main pump. It is very important to be careful on removal (don't chip, exert excessive force, etc), as you can damage it. It comes out relatively easy with a larger pair of pliers and/or wrench. Wiggle it back and forth to remove it.

Step 6: Again use the screwdriver on the back of the pump, and screw on the new needlewheel. Get it tight, but not too tight. It should still spin a dozen or so rotations easy if you spin the unit by hand.
Step 7: Reassemble

Thank You - To be safe I'll install a ball valve between the pump and skimmer. I can't imagine that I'll need to trim the 250 back much more than 400~500 GPH.

if you can, use a gate valve .. it will allow you to dial the flow in much better.

3/4 or 1" I would use the 1" that way later if you sell it or need to put more water through it you can. but that said you can still use a reducer fitting before the inlet piece so you could go bigger or smaller for what ever you want.
I used the 1" but use a threaded reducer to 3/4" hope this helps
