Need help deciding on a tank changing gears

[Bythesea]

I have a problem I created, I have an IM micro 30 almost ready to go just need rock and sand,but I just came across a beautiful 75g bowfront tank matching stand and canopy for a good deal. What should I do buy the 75 and start building slowly while running the 30 till i'm ready? just keep the 30? or sell the 30 not even start it uo? you have to understand this is my first tank from what I learned the bigger the better. Hope you can help me out.

Go with the 75 and don't even start up the AIO

Go with the 75g, don't start the 30.

Going to run the 30 first this is my first try at reefing the 30 is ready to go except for rock and sand , the 75 will sit till i learn enough to know how i really want to set it up so i don't waste time and money.
