Okay I am going to give some constructive criticism here. Please do not think I am flaming you, okay?
When you come on here and ask people what they think of a particular stocklist and equipment and they find some problematic issues, it is kind of contrary to disagree because you wouldn't have asked in the first place, if you were sure it would work. We are simply trying to save you money, time, and frustration...
That being said, I think that you should definitely tweak your stocklist a bit. Like maybe instead of a volitan, get a smaller lion, and if you are set on the lunare, skip the trigger. This is a stocklist suitable for more like a 150 gallon honestly. Lunare wrasses get very large and can be very aggressive later on.
As for filtration, dont spend a bunch of money. Invest in one good skimmer for now and then later on as your bioload increases, definitely add a DIY sump. You are not going to add all these fish at once anyway, so you have some time. Defnitely take this one slow and allow the bioload to increase safely.
And remember, pictures make this all better and more fun!! So please share once you get it up and running!!!
