Update:
After testing out my initial 150 gallon tank, I couldn't get the damaged bulkhead to seal properly. The manufacturer (SCaquariums) replaced the tank. Great service by them.
Since then I've gotten the old swapped out for the new. I also did the plumbing last night. See pic. I decided for now to go with tubing on the return as I may add something more permanent later. (jaebo dc12000 return pump). I also have flex pvc straight from the union going into the refugium section for the E-drain. I'll likely trim that down later on if I like where it's at. Lastly the main siphon has the gate valve with one 45 elbow and the rest flex pvc to the sump bulkhead.
All three bulkheads looked good on a quick leak test. And all three bulkheads have unions immediately below which isn't visible in the picture.
In other news, I have 2 clowns in QT. Named them Fizzbo and Flash. I started with TTM on super bowl Sunday, and after 12 days moved them to a 20 gallon long QT. I recommend doing the TTM. It turned out to be pretty easy using 5 gallon buckets. I followed the sticky on it . Dosed with Prazi on two of the transfers.
One of the things it doesn't mention much is that water changes are acceptable, so long as temp and SG are matched. This along with Prime can keep your ammonia in control, especially if you have 2 fish in a 5 gallon. Feed lightly, siphon excess food, waste out.
Fish are eating well, seem to be healthy. I have one spot on the snowflake clown I'm keeping an eye on. It may just be a white scale, but it'd hard to tell and the one downside to starting with buckets is the lack of horizontal visibility so I have no idea of before/after. It's definitely not ich.
20 gallon long QT is cycled and doing a great job so far of keeping down the ammonia. I did a 20% water change on Saturday and will keep doing so until the main tank is ready.
My next steps are hanging lighting above the tank, and ordered rock, sand, and the skimmer. Hope to be running main tank and cycled by end of April.
