Review on 💦 AQUANEAT 4 X 2 Inch Large Air Stone Cylinder: Essential Accessories for Hydroponic Growing, Pond Circulation, Aquarium Fish Tank - (4 Pack) by Jessica Hall

I use these for DWC hydroponics, they are high quality and work well. I have a 960 gph air pump so the bubbles are very strong even though they are divided into 6 parts. These are good air stones - I would recommend them. However, if you're on a budget: check out the Penn Plax 10" Air Rod for less than $5. The surface area it releases bubbles on is huge - one of these can replace at least two. Like I said, these Aquaneat are a great product 5 stars but I have since found a better deal at Penn Plax ($3.49 at the time of this writing) It's worth noting that a 1.5w air pump may not have the same effect as my powerful pump has.This applies to both Aquaneat and Penn Plax.I am currently using the equivalent of 6 watts to pump air through each and the bubbles come out fantastic.I can't vouch for less air pump power but I do will test it soon and update this review.
