Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I don't know Chris. Now that you mention it, it does look like star arms, but I have treated a few tines in different tanks and never had an issue with any livestock. Maybe you have something in the tank taking him apart, Crab or shrimp perhaps.
That the one
I should add that I use a BlueLine 55 for my return. Used exclusively as the DT return. Full open it pumps around 500-600 through my 180. Which is right around where I wanted it. That's about 13ft of head plus a few fittings. I used flex PVC to reduce fittings as well.
Looks like it might be right but add in a fitting here and there and you might as well blow the water through with your lungs. I would invest in a good pressure rated pump and call it a day. The only internals I've come across that can compare are a line of sicce pumps, can't remember which though.
