I got one “pipeline” completely glued up last night. I try my hardest not to get primer all over the outside of the pipe, but it never fails; I always end up dripping and spattering the primer.
The distances between the holes isn’t quite the same, 1/8” difference here, 1/16” difference there. I test fit the return line in the tank after the glue up was done. I decided to just have the bottom holes be returns for the closed loop.
As for the pesky hole on the right hand side off by itself, I decided not to use it for the closed loop. I might use it as a third sump return. For now I’ll cement an elbow and enough pipe to extend past the fill level of the DT.
This afternoon and evening I’ll finish the drain “pipeline”. It’s about halfway done now.
I’m going to mount the closed loop return line today. That’ll be the hardest “pipeline” to mount because I can’t fit back there. The sump will have to come out and I’ll have to reach up the back to get the farthest bulkheads where they need to be. Kathy is going to help me by pushing the two closest bulkheads into place.
The drain pipe, which will be inserted in the four holes directly above the return pipe, will be easier to mount. I can get on my stepladder and bend over the DT to get the left bulkheads in place while my wife gets the other bulkheads pushed through.
So far my leptospirosis frags are doing well. Dory is hiding less and when she comes out she swims a little farther than the time before, She’s eating NLS pellets right now but tomorrow I’m going to feed her nori. Hopefully she’ll take it. I’m not sure if they’ll eat chaeto or not but it’s in the tank if she wants some. There’s also some hair algae I’ve purposely allowed to grow knowing she was coming to Perseverance Reef.
It would be a bear but I might try to get move the tank just enough for me to be able to get behind it. I’d have to get about half the water and half the rock out at a minimum but it can be done. If I do that I’ll be able to mount everything with the flange side in the DT.
If not I’ll likely mount everything with the flange and seal on the dry side. That would make it easier to remove if I had to but it wouldn’t look great, at least not until my aquascaping hides them.
