25 Feet Airline Tubing Standard Aquarium Air Pump Accessories Set with Suction Cups Connectors and Check Valves for Fish Tank Aeration Setup

Haven't been using for a long yet. Quality seems good and glad to have options for the splitters and additional check valves.Plan on regular cleaning weekly and it should perform well. Will update if that changes!

I bought a new air pump and this set to go with it. I wish I hadn't. Air stones are crap. The first air stone I used worked wonders for a day or two and then crapped out. The second one I used lasted like half a day and then crapped out. Tossed the stones and just spent some money on some never clog air stones from Aquarium Co-op.Listen to the reviews. The suction cups are crap and poorly made. I literally gave them a pretty good chance before determining that only one suction cup of the whole bunch worked. The rest would pop off within 24 hours.The valves also came pretty dirty looking and seemed to have some kind of salt inside and all over them. In fact everything in the bag was covered in a layer of salt, not sure if this was from the stone, but it was a pretty good coating.The air splitters are probably the best thing in the bag and they are made of cheap plastic and appeared to have undergone not a moment of quality inspection.All in all you get what you pay for, stop being cheap and pay for the good stuff. You won't kick yourself for doing so like I did.

The media could not be loaded.  This set included everything I needed to add air to my 10 gallon fish tank. I soaked the stone for about 30 minutes prior to installation and used the suction cups on both the inside and outside of the dish tank. They are still holding strong and the bubbles are just as plentiful as they were the day I installed it. Highly recommended.

Bought this kit for an experiment I was trying, mainly for the valves and T fittings. The valves work a bit but backflow is substantial and the Ts leaked in the tubing. I suspect the airstones are fine and maybe I will get some fish.

Both airstones I received allowed almost all the air to escape very near where the hose input is, not evenly throughout the stone. Completely defeats the purpose of a large airstones. Additionally, the check valves emit a high pitch squeal making them unusable. NOT happy.Update: after running them for some time and extensive cleaning the stones are working better. Check valves are still obnoxious to the point of being unusable though.

I have both in my fish tank they work great my fish love swimming through them and I have 2 different pumps on them and if your pump is quite the air stones are quite easy to set up and the check values are great as well dose what it says it dose

Nice little package. The suction cups were a bit distorted and popped off of the tank. After reinstalling them they seemed to flatten out and are holding.

These put out plenty of bubbles for a 40 gallon breeder tank. Anything smaller, that isn't deep, they are a bit much. My 20 gallon long tank is too shallow and it was too much. Great product!
