FluvalPlant Nano LED Aquarium Lighting with Bluetooth, 15 Watts

This light is awesome! I’ve noticed more growth in my plants and the whole tank can get the light since it shines all the way to the bottom of my tank.

After reading and watching reviews on this light I wasn’t really expecting much tbh.1) The mount doesn’t work with a normal tank rim so I ended having to notch a small piece out of the lip where the lid would sit to make it work. Not the end of the world but could be designed better. Seems the mount is only made for rimless tanks.2) the Bluetooth control app although easy to install and setup takes some time to figure out how to use. It’s bit very user friendly but it does everything you need it too once you figure out how to use it.3) The preset light settings are horrible you will need to make your own settings. They are way to powerful in the wrong spectrums.4) if light looses power it will not turn back on until you connect back to it through the app as if all the settings are not stored internally with a capacitor and it doesn’t remember what to do wo connecting back to your phone.Now on to the good things..1) has way more power then given credit. I can cook sps with this thing if I need to. I haven’t measured the par but on a 10g pico this is installed I and getting fast growth at even just 60% v-b and 8% whites.. I have no doubt this light can be used on tanks up to 18” deep long as you keep sps to the top 2/3 of the tank.2) the light spread is way underrated. Most value lights are going to come with 90* lenses this lights 120* lenses really shines. I’ve got sps all the way to once side of the tank near top and it’s wncrusted it’s plug in just 2 weeks wo 2 part dosing.All in all I think this is a great light. Just enough shimmer wo getting that cheap disco ball effect. The swiveling if the mount for easier access to tank is great and you’ll be using it every day. It could be a bit more range in the swivel but it’s wbkugh I can swing one way and access that half then swing the other way for the other side. As low as this light sits over the tank this is a big must and it has it. There is very little shading anywhere and considering this is a 20” Long tank with just a 5” light mounted only 6” above the surface I tend to think even that 120* lenses ratting is a bit under stated. I’ve dropped water all over the light wo issues. The mount has plenty of adjustability for any size or shape tank you’d be using this on. I wouldn’t hesitate to use 3 of these in a 40g breeder setup on bit.The “cyan” coloring is not the normal cyan you find in other lights. Most of the time this is a version of your whites and greens mixed.. on this light it’s not. This is your light blue spectrum and the blue is your royal blue so don’t short yourself on this when designing your own profiles.FYI the reds are way over powering and I recommend not using them at all unless you like growing algea. I’m running 100% v-b-c no reds and 8% whites now after starting with 60% settings while corals were acclimating to tank.You have all the features of the HD primes, kessil, and radion xr lights with being able to adjust specific intensities, spectrums, with custom times allowing for ramping up and down. You can even if you want under the pro settings adjust when each color spectrum starts it’s ramp. For example I use just v-b on one hour ramp to 100% till 5pm then whites ramp to 8% then at 10 everything ramps down together to 5% blue moonlights for two hours then dark resting period. This way I’m only blasting with whites for when I’m around to view the tank and only enough for my viewing preference.If you wanted to run this on a sps only tank you can up to 18” deep I’m sure of it. The only issue is you’ll likely have to run whites at max to get the par up.

I actually have 3 of these lights, the first on my small 3 gallon tank. First off, yes, this light is bright enough for larger tanks but bear in mind that the tank size and shape does play an important factor. I bought a second unit to test on my low-tech 20 gallon long rimless planted tank. It's 36 inches long, 11 inches deep and 12 inches wide, so not as tall when compared to standard tank sizes. Even at 45% a single Nano was bright enough to keep most of tank adequately lit and gave enough light for my plants (mostly moderate light requirement plants) to establish themselves during my dark cycle. I ended up getting another one and now run 2 of them as I prefer to have more room to manage my plants without having to take an entire light strip off.However, do the research about aquarium lighting. The deeper the tank, the more light falloff you will see as it travels through the water to the bottom. Also take into account how thick the substrate/aqua soil layer is. If you're wondering about PAR values, apparently a site that tested it reported that at a height of 12 inches and 6" from the back wall of the tank, the Nano's PAR value was 68. But take that with a grain of salt.Other than that, my thoughts:Pros- Bright, easy to install. Solid construction.- App is super handy, no issues with it connecting (iOS). Love the timer function- sleek design, not bulky- can save lighting profiles in the app and apply it to another Nano or Fluval light if you have one.- Bracket mounts on the rim with no issues and have rubber padding. Note, the glass on my tank is 8mm thick. From what I can tell, this would be the max thickness, as I don't really have to tighten the mounting screwsCons- While the app works, it's clunky. Would be nice to enter in the brightness percentages by typing, but you have to use sliders. There's also no "undo" button.- Can't really link 2 lights together. Need to save one profile and then apply the setting to another. More of a nice to have than a necessity really.- Have heard some Android users have had issues with the app.

These small lights are great for small aquariums. The Blue Tooth controls work great. The APP controls are sophisticated.My only complaints would be the bracket does not hold the lamp perfectly level, and the salt buildup because the lights are so close to the water surface.
