SEEKING ADVICE: Skimmer and flow

I own a gen2 bubble King 200 mini, which i've been thinking to use on my next build (75g display tank + 30g sump). In addition i'll be running a filter roller. My concern is that the skimmer is oversized and that i might be better with a smaller or simply run my system without a skimmer.
I also have a ghl maxi doser, which either is going to be used for continuous water change or feeding bacteria with vodka/sugar/vinegar.

Another question would be if 1 mp40qd and mp10, is sufficient for a mixed reef tank (mainly sps) . Tank dimension: L: 40 and W: 25 H: 20 inch.

I can currently get another mp40 very cheap at the moment~100$.

Thanks in advancd!

Having a larger skimmer isn’t really an issue. Worst-case you’ll be emptying in less frequently, and if your bio load does change you won’t have to upgrade.

I’d get the second MP40. You may not need the MP10, but it will be easier regulating flow with two wavemakers of the same size.
