Suggestions on sump?

[Jim the noob]

Hi guys, im considering getting a sump for my reef tank and could use a little help on the matter...
At the moment i have a 200 liter tank (not drilled) and would like to be able to use the same sump for my bigger tank ill get at some point, im thinking about 1750 liter /460g,
i know skimmer and some other equipment might need a change by then, but would be nice to re-use the sump..

my thoughts are:
-Filter roll
-macroalgae refugium
-a skimmer ofc.
-and a chamber for coral growth..

Anyone got any ideas that could get me i the right direction?

I would get as big as you can fit in, because you will always need more space when you start adding stuff.
