Super easy to install, you need to buy a blower motor for it *we used our old one* but it works well, very bright adds a lot of fun to your tank!

Love this brightens up my fish tank

**UPDATE: this product has completely stopped working. Turning it "off" would only turn it to red light, and there was no way via the remote or the direct control button to actually turn the light off. It has since stopped allowing any air to pass through and came disconnected from the bottom of my tank. I wish I were still in the return period! Original review: I had high hopes that our air pump was strong enough (rated for 60 gallons, in our 40 gallon tank) that this product would work for us, but alas, I should have trusted the negative reviews! We can, occasionally, get bubbles out of up to three holes on this bar (and yes, we've tried tilting, angling, blocking holes, etc... that helps for maybe a minute before the bubbles stop). We now have hooked up an air toy to the other end and just let the air escape there, instead. It's very disappointing when you splurge on this product for the wall of bubbles and the visual effect that imparts and you get a pitiful bubble stream instead, but the lights do look nice and I won't go through the effort of removing this from my tank. FYI, for those using a 40-gallon breeder, it fits but only just: the air lines on either end will be sharply bent, although it was enough for air to pass in our setup.

This is a good product IF you can get it to work properly. It took well over an hour to get this set up. Not the products fault; you should add this before you set up your tank. Once set up you will need a strong air pump. I had to adjust the length of my tubing several times even with a strong pump. I would also suction free end to tank wall not floor. Bubble holes had to be cleaned and poked several times, water pressure build up helped 'blow' holes out. Remote has to be pointed at switch which is geneally behind or under tank. Cannot point at light in water. Does look good after its all working.

This one is bigger than my previous one I love the lighting just wish I bubbled equally threw the bar...it seems to skips spots.

Love this bubble light for my fish tank works so well I love the fact you can change colors or patterns I would recommend to anyone

I purchased two 20" in the beginning of september 2025 and used them in my 75 gallon and 40 gallon freshwater aquarium tanks. The one put in the 75 gallon had the colored lights quit working after day one so only one color was on at all times....I could not change the color. The one in the 40 gallon works well but as of today, 12/29/2025 the color lights no longer work. The air bubbles still work on the one in the 40 gallon tank but the one in the 75 gallon tank is losing energy to create bubbles. I have a warranty on both and glad I do because I will keep replacing them until the company can get it right to have them work properly for more than three months....

It took a while to get the bubbler functioning properly, probably about a week. I initially had to play with the angle of it to get bubbles to come out of every orifice. Now at 2 months in I no longer have to play with the angle, it seems to work fine even when the bubbler gets moved. My fish tend to like the lighting from the bubbler more than the lighting from the overhead LED lights. They tend to come out more when only the LED from the bubbler is on. The 20" bubbler is the perfect size for my 29 gallon tank. It comes right up to the filter, but not so far that it effects its function. The only downfall so far is that the suction cups let go every 2 weeks or so and I have to reach in to readjust it's position.

Beautiful 😍
