yeah you should be fine, I seen too many mixed reviews for your skimmer on my 90 gallon. like I said it should be more then enough for your 40gallon.
The ASM skimmer I have now is working great with filling up that cup, I just need piece of mind. Ever since I had issues with my 55 and they seems to be resolved by upgrading to double what I needed for a skimmer I live by that now.
Look at the beast I had Matt build for me all that for a 630 gallon tank.
This skimmer is super quiet which is awesome. Right now it's throwing out some microbubbles but it's still breaking in. I have pre cycled marco rocks and about 30 lbs of caribsea seaflor spec grade reef sand so the skimmate so far is pretty clean just a little hazy. Looking forward to adding fish in the next couple week or two. Lmk how you like the msx!
