I also bought the same day, and tested these all three together, in order of performance : amazon.com/gp/product/B00MT718Z8 and amazon.com/gp/product/B00025652A
One of the three boxes said to soak the item for 15 minutes prior to use. I tested them all without soaking, and then after having soaked in room temperature water for 20 minutes. All results were consistent. They all performed much better after having been soaked, but the top performer was still very clear.
If I need any air to water I will be purchasing Hydrofarm.
4 month update:
After 4 months in dirty conditions amazon.com/gp/product/B00MT718Z8 is performing better. The Hydrofarm is clogging so badly it's barely functional and needs cleaned every 2-4 weeks, the off brand one mentioned though producing larger, fewer bubbles, isn't clogging noticeably.
Pros: Very small bubbles, if that's your thing. [Note: This doesn't really matter that much for hydroponics DWC]
