Will these lights function properly if placed at the top of the fish tank? Will they shine down into the tank and bubbles as well? How to do it?

Because the lights are very small LEDs, they are not powerful enough to project their glow down into the water if placed over the tank (in the air). If you mean that you want to place the lights inside the water near the top pointing down it will be difficult to get the unit to sit properly so that the lights point down. The suction cups hold better when attached to the back (opposite the lights) where the unit is widest. When they are turned to hold from the side (where the unit is thinnest) more of the suction cup is exposed to the current/bubbles and it doesn't hold nearly as well. I'm thinking if you want to do that you may need more suction cups to hold it in place and also some tall structure to hide the unit because a black light bar suspended at the top of the water is going to look silly. When its on the bottom you can hide most of the unit under the gravel/substrate.

Use use the bulb in a fixture designed for the top of a fish tank but my husband thinks that yes it would fit into standard fixture

Probably not bright enough for a reef tank. Marine land makes one that is reef bright though. If you were using it in conjunction with other lights to fill out the color spectrum and add intensity it would work. Other than that I've been pleased with mine, I did have an issue with it, but marine land had a new one to me in under a week.

The fish tank takes 4 AA batteries, and the bottom black platform is where the 4 small LED lights are. There is an LED bulb in each corner of the base, and they light up through the water. I would suggest using clear aquarium beads, or light colored, so the light can shine through. I use a light blue, and it looks really pretty. Also, at night, the light reflects off of the ceiling and you can see the fish's shadow swimming around-very cool.

When you first purchase this item, it's possible the lights may not work due to remaining packing material within the hood. Remove the hood portion from your aquarium and flip it over. On the underside you may see a small, square piece of cardboard (or packing material) wedged on either side of the hood or closer towards the middle near where the switch is - this prevents the switch from making a full contact and thus some or none of the lights may work. If you remove the cardboard from the underside of the hood and place it back on the aquarium, the lights should be functional. If the lights still do not come on, you may have a faulty hood piece/lighting.

I had a couple floating ball plants in my tank with this light. Sorry I don't know the actual plant name. They did well before they became too algae covered (a problem I've been having with this particular tank). Therefore I think this light would work with the plants you mentioned. Hope this helps!

Yea for sure I'm using one light fixture on my 90 gallon tall tank which has a similar footprint with a 40 gallon breeder. 36 inch long 18 inch wide and 32 inches tall. The light is plenty strong make sure you hang it a east 12 inches from top of the water to get good light dispersal for a three foot tank. Also takes some careful aqua scaping so you don't get any shadows on the side. Mine looks like a volcano very high in the middle and slopes down on both sides so as not creating casting almost any shadows. I run it at almost 80-90 percent and eveif I ran two I would probably not have aqua scales this way but I like the look and my coral in the bottom sandbed are getting enough light. I get ton of coralline algae on the sides of the tank so I am pretty confident the light is spreading enough. I don't have a gazillion corals so I did not see the need for more than one light and having one now I can definitely see that I can surely add more in the future without any problems. I am even having luck with sps corals so this is the real deal! You will definitely not be able to run them up that high intensity since the breeder is so much more of a shallow tank but that's good because you will be saving on electricity, also another reason I ran one light... Make sure you a climate your corals from very little light these lights are super powerful!

the lights can't be chained togeather. When I had my lights in the water on the bottom of the aquarium, I didn't like the look. You could see each LED lite. I have them ontop of the tank shining down into the water. Much nicer, I think

I would think its a stretch ---- the light if attached to the end of the tank, its edge would barely reach the the middle. If attached in the middle, you would have dark areas at each end. Perhaps two units would suffice.

Hello Bill, I'm not familiar with Glo Fish...I have Gold Fish and they shine very bright under the LED lighting. Hope this helps.

It isn't really designed to light up an aquarium, it is only to increase aesthetic appeal by creating pretty blue bubbles. It wont be too big for your aquarium, it would probably look fantastic.

the lights can not be turned off unless you unplug them. I did not like it in my tank anyway. you could see the light bulbs so, that was your focus. It was much nicer when the light was ontop of the tank shining down into the water.

I have mine mounted on the front of my garage, with the bottoms about 6-8 inches higher than the garage doors, and they work just fine. In fact, I have had earlier versions of these same lights mounted there for over 10 years, and they always work as advertised.

Should be a clean bright light same as cool fluorescent bulb, not like a warm light. There can be a slight violet tint depending on contents of aquarium

Sure, you could do that. Heck, on my 75 gallon (that I have 2 of these fixture on) I took everything off, and just put the lights on, no glass cover or anything. I did make a little blind for the top of the tank. Remember, these lights will be a few inches above the tank. So if the top of your tank is already higher than eye level, you WILL see the bulbs, and it can be a bit bright.

Depends on tank size, mine is over a 20 gallon tall, and is successfully lighting duncans, hammer, and various favia and favites. Also look at the reef breeders nano par 38 lamps, they're not too much more $.

It depends how deep your tank is, the light itself is bright and very directional the tank and the light must be the same size. To be honest I was a bit disappointed when I got mine, the blue LEDs are not strong enough in my opinion.
