I agree ^^^
I started with a 75 and love it, in fact so much I got a IM30L AIO at the first of the year and started another dedicated LPS tank. Used tank, lights, power heads and pump, rock sand and water less than $800. 75, homemade sump, skimmer, pumps, power heads, lights, apex...++$3000,
the maintenance is easier for sure, equipment was less expensive, fish selection is limited but I’m finding a lot a pleasure in smaller. Trouble is it fills up pretty quickly. Both are great ways to start, 75 is a lot more work (just spent 3 hrs doing the 6 months cleaning of the sump and equipment) but is in fact more stable than the 30. 40b would’ve been my 2nd choice
