Submersible Bubble Aquarium Light：Multicolor RGB Fish Tank Light with Remote & Adjustable Brightness for Pet Plants Grow - Waterproof Submersible Led Lights for 5-10In Saltwater Tanks

Very strong bubbles. I tried lowering the amount of bubbles using a valve on the line but then the bubbles only come out of the first few holes and nothing out of the rest. There’s no way of modifying the intensity or amount of bubbles coming out. I would not get this if you don’t want violently turbulent water.

Love this brightens up my fish tank

Had high hopes for the dual light setup considering it was cheaper than the single I got from a different company. The LEDs were visibly different in both, like having 20/20 in one eye and astigmatism in the other. It was in the tank maybe 2 days, never had bubbles come out of More than 2 holes at a time. And just wasn't good. Makes sense why the other guy was $20, and it throws an amazing light in 24/7 mode.

**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.
