This is #1 for me! Can’t stand it when people say I need a light under $100 bucks for my 55g. Take your time when doing a build my current grow out build is a year plus, people may say that’s a crazy expensive build but I do it at steps and save so for example my custom bashsea sump was 2 grand I saved up for a few months and ordered it then a few more months saved and bought something else. If I didn’t do that it wouldn’t look like it does today!Invest in good equipment once instead of buy cheap and wishing you had spent it in the first place
