Aquarium Air Pump Airline Tubing Kit include 1-Pcs 2-Way Outlet Air Valve, 2-Pcs Air Stone, 2-Pcs Check Valves and 6-Pcs Suction Cups Fit for 3/16-Inch Fish Tank Air Hose

This is a complete airline set for anaquarium air pump. I've actually used it as a set-up with 12 inch airstones to humidify some vanilla orchid plants. It even contains a couple of extra parts. The airstones included are slightly less than 2 inches in diameter and they work well (I just needed to use larger stones).It uses standard airline tubing, but there is one thing that I'm not thrilled with about this set. It's really hard to attach all of the connectors, except for the airstones. They seem as they are just a bit too large. They are on, but only about 2-3mm, and I'm always afraid that one will blow off from the pressure of the air pump.If you're looking for a set like this, take the time to look around for another or just buy everything separately.

I bought this for my 75 gallon freshwater Cichlid Tank. The air stones put out a nice even layer of bubbles. The stones where a lot smaller then I was thinking but sill work great? I just didn't look closely at the size of them when I bought this. The 2 ways adjustment knobs seem like good quality and seem to adjust very well. I haven't had any issues with the suction cups they hold onto the glass well and don't have any bad odor like someone else mentioned. I definitely would recommend this to anyone looking for an air stone kit. I would definitely buy it again.

Not incredible impressed, I attempted to use the air stones - but neither of them worked (wound up buying those from local pet store). I haven't used anything else from the kit just yet, but I remain optimistic that the other pieces will hopefully work and serve their intended purpose. I do enjoy that it all arrived in a nice little blue snap shut type box, keeps it all together nicely!

The tubing and suction cups have a very offensive plastic odor. The cups started to rapidly degrade in the tank and made the water smell awful. I have since removes them and the water smells like it should now.The airstones are pretty good. They disperse bubbled uniformly and work well in a 75gallon tank.

great simple item, I needed this to get better air control of the 2 air stones in my sons tank, for some reason the air flow favored 1 stone and nothing came out of the second one.I didn't use the stones in the pack, just the control valve, 1 way valves and suckers. and for the price they are really quite good.

Good price, good quality, valves can be adjusted to change which line gets more air pressure, check valves protect the air pump, the suction cups keep the line tucked away and the airstones work great.

Bought this to go with my little Pawfly Air Pump and it works beautifully! I like the whole kit and it's definitely affordable. VERY satisfied with this product and I use it to pump air to both aquariums with the one little pump. Thank you for a great product!

a lot of accessories for a small amount. One of the check valves did not work. I did not want to hassle with return. So, I took it a part and made it work then glues it back together.
