Hello all, I'm currently planning a 125 Gallon Saltwater Aquarium. This tank would most likely be FOWLR, with the possibility of some Zoas, since Hawaii state coral laws are very strict at the moment. I have a doc linked with the products I'm going to use to build the tank alongside my stocking, and was wondering what your thoughts are on my possible setup, stocking, etc. Thanks!

OK James, I am not much of an equipment person. However, I can bump the thread for you.

Consider starting a tank journal in members tank forum.

PS: When you mention strict Hawaii coral laws, does that refer to corals in the store? For certain, hobbyists collection is illegal.
 
I have had some good experiences so far with Hygger pumps and powerheads, currently running a Jebao DC return pump, and hygger wavemaker and powerhead in 75g tank for 1yr, no issues. Best of luck with your build!
 
A 125g is a great size for FOWLR with room to grow. Your plan sounds solid , just make sure your filtration and skimmer are sized for your full stocking list, not just the starting fish.
Zoas should be fine under moderate lighting if you decide to add them later. Overall, looks like a good foundation. just stock slowly and plan around adult fish size.
