I concur with Rex. You'll need it for DIY. I did it without one for a while and what a mess. There was always this slime buildup on my ladder/diffuser. And the bubble count is not all that relevant, since it'll fluctuate over time with DIY. If I were you, I'd get a drop checker. I just ordered two from Blacksunshine here.
