Carefree Fish DIY Aquarium Nano Materials Air Stone Strip Ⅱ Fish Tank Bubbler Hand to Hand Make Fantasy Bubble Walls Make Super Tiny Bubbles （Air Pump Not Included）

I got the 150mm (5.9inch).Great packaging, very well protected. I did not use the suction cups, but I'm very happy they were included, with all 4 being used I can see that thing never moving. I used the beach sand in my tank to hold it down, since the bottom of the tank is like 1.5 inch's under sand. I'm sure they would be great to mount it to the walls of my tank if I ever wanted to. My soft cloudy silicone air tubing fit this air stone, but my clear stiff air tubing did not fit it.I have a 29 Gallon saltwater tank. I have ruined 2 bubblers when I first started this hobby by not soaking them long enough and not removing all the air in them, before my first use/test. I now go overboard with following the instructions plus extra. I put the air stone in my tank with the opening end facing upwards to let out air. I left it in my tank fully submerged for 24+ hours before testing. Works great (more bubbles on the side connected to the air tube, but that's with every air stone I have used so far, unless I put air tubes on both sides if available or provide a ridiculous amount of air to it).I actually had to turn the air to low with this air stone, since the tank was developing to many air bubbles on everything (Mine is located next to a 100gal submerged pump, so the bubbles were getting caught in the current).I only have 1 conch and 20 or 30 sand crabs right now, so I think I will use this when I have at least a few fish in their also, or my submerged CO2 detector says there is an issue.FYI: I also have 1 regular 30gal max hang on back type filter set to lowest setting and one submerged filter for water circulation set to it's lowest setting (Those two are probably good enough without help...To bad for now...Micro bubbles look very cool).Those micro bubbles look great with my underwater led lights right behind them.Update: I ended up continuing to use the bubbler and after another week the bubbles evened out. The whole unit lets out bubbles evenly, even at lowest airflow setting its pretty even. Great product! I also think 2x6" would cover the back of my 29 Gal tank properly, right now one 6" stone just makes me want to get another.

Been using for a while and works great. Pump must buy apart.

Does the job but you need a strong air pump

I really tried to ignore the bad reviews of this and just couldn’t beat the price so I took my chance and was sorely disappointed in what I got. Bubbles only came out of one side of the air stone and each day the bubble flow was reduced. After 3 days I had to give up and swap it out with a different air stone I had on hand and returned it. Don't waste your time

I wanted a new look for my tank and I was not disappointed. Contrary to standard air stones, this emits a wall of very tiny bubbles that are not only beautiful but effective for aeration. The price makes it a good value and it comes with a variable air valve as well.

The media could not be loaded. I really like it, looks great in my 30 gallon tank..

I love this. It provides a nice mild bubble source for the fish, who like to go into and then be pushed up and out of it.

Buy this with confidence looks and works great
