This is the exact model regulator I've used for years from Green Leaf Aquariums. It's a single-stage with fine needle valve.

Unlike many, the bubble counter is useless to me as I use it in conjunction with a pH controller. I know it's old school but it worked for me to monitor my daily pH drop and how quickly I was getting to it.
So let's compare equipment.

Show me what you've got and why did you choose it?
In all honesty, I chose this one because it was relatively cheap and had good reviews. I think the regulator is one of those parts that you DON"T want to skimp on because it's so crucial. However, I also didn't have the budget for more. Seemed like a good compromise and it's been working as intended just fine.Unlike many, the bubble counter is useless to me as I use it in conjunction with a pH controller.
