I'm pretty happy with this list. Maybe a few modifications to it but for the most part I like it.+1 on the research. Lot of ways to skin this cat.
At first glance:
Skimmer: SCA 301 or 302 if your sump is large,
Sump: the biggest you can fit in the stand. Maximize water volume
Fuge: yes should be part of the sump, maybe use a 40b and build Fuge/ sump
Circulation: what Ted said
Return: DC 3000
Media: run k1 or hel-x media
I agree with you and ted. The past couple months I've made some mistakes going too quickly, but I've also learned from them. Now I'm going slow and steady. I know the maintenance involved but I also try to stick to a routine and haven't had any quality issues. Only pests, which I'm hoping won't be a problem from here on out since I'll be dipping coral and have a QT. And buying quality equipment with backups should stop catastrophic events from happening. I've been trying to get my tanks setup the right way the first time so I don't run into issues like the overflowing 27. Now I shouldn't have those kinds of problems. Hopefully over the next few months of getting the equipment and starting the build you guys will see that I'm doing things the right way instead of the cheap way beforeI have to agree with most of what Ted has said in this thread. If you think it cost a lot now going too fast will only cost a lot more in $ and frustration . It's ok to hold on to the tank and get situated and comfortable first. Some of us have paid the price and only trying to help you learn from our mistakes. There have been a lot a people that burn out of the hobby because they turn it into too much work and not just enjoying it .
I thought the same thing. And I don't think any pipes would clog since I run the plastic cone shaped screens on my drains. I thought the first idea was fine or do I still need one tank draining to sump and one tank to fuge or just both to fuge. There is 2 1" bulkheads on the back of my fuge that will connect to the 2 1" bulkheads on the back of the sump. And imo with a ball valve and union on each pipe there should be no chance of overflowUnnecessarily complicated, people have a fuge in the middle section of their sump all the time (including me). If you don't mind the complexity then go for it, but also keep in mind that each ball valve, union, bend, etc. creates a restriction.
Ones a 18" or 20" cube and ones a 24" cubeList looks fine. I'd consider getting the possum for the 24" cube and something else for the 30" 29g. Maybe a small coris wrasse or something along those lines.
