🐠 Pawfly 8 Inch Aquarium Air Stone Cylinder for Outdoor Pond Garden Circulation System, Fish Tanks, and Larger Pump Bubble Diffuser Review

In my opinion the best air vent for large aquariums. However, make sure you have a powerful pump. Full power for the 1st video and 1/3 power for the 2nd video.

Looks like the water is bubbling. Just like a year ago with my new air compressor. Hopefully I won't have to replace it every 8-10 months but the price isn't unreasonable if I do.

Now I am going to grow bubbleponics. Forget any disc or cylinder bubblers. Many don't know, but this is one of the top 10 bubblers of 2020 and I will be buying it again until technology advances.

This is by far the best air pump accessory I have had, the performance is amazing. Fair warning, you need the right pump to make it work efficiently. I have an Ecoair 1 which is about 18 watts so it works great with this Aeroston. Anything less probably won't work either.

Two of these provide more even aeration with tiny bubbles for my Pondmaster aerator than the 6 2" balloons I had. I immediately ordered two more because they work so well. (Please remember to soak them in water for a few hours first before attempting to blow air through them!)

These things are huge as people say lol. They work great. it takes a big pump to propel a stone. I like the weight, I'm sick of the lighter ones moving, floating, whatever. they are of good quality. there is only 1 entrance for each stone (no double entrance). I have 2 in an 80 gallon tank, honestly it would be fine.

These air stones are sold in sets of two. One is completely blocked by the packaging material and the other is only partially blocked. None of them will work. Yes, I soaked the stones for a certain period of time. Yes, the air pump used has the corresponding capacity in l/min. IF YOU BUY THEM YOU MUST BE STUPID

Stone diameter 1 33/64" (ie 1.5"); 3/4 of the stated diameter and the exposed face of the stone is only 7 1/4" to 7 3/8" long making the surface 70% of the stated size. Add to that the fact that it's a cylinder so the inside is smaller than the outside and the product is much smaller than the capacity of an 8" disc stone (which has the same surface area as the stated dimensions).

Like many things imported into this country that are not labeled properly or appear not to be what they really are, these "Air Stones" are made of carborundum! What is carborundum? It's a "stone" made of silicon carbide, or what we call "sharpening stone" in this country - when people sharpened their own tools and knives. Obviously they are man made, quite dense and heavy. One of two "air stones" that I bought. one of them was not properly drilled and did not let air through. It went straight…
