How do you mount this/ attach this to the aquarium?
Answer by ChewyJan 08, 2020
This light attaches to the frame in the front of the aquarium with clips.

I have a Top Fin 20 gallon aquarium. It has white LED lights but I want to replace with the glow lights. Will this product work with that tank model?
Answer by ChewyFeb 27, 2021
This light fits tanks up to 20 gallons and will work for a top fin aquarium.

Does this plug into a wall or just work with batteries
Answer by ChewyOct 14, 2020
This LED Light must be plugged in to work.

Is there a remote to control what color you want?
Answer by ChewySep 08, 2020
This LED Light does not change color with a remote. You will simply press the button to turn it on and change to the settings that you want.

What about the rimless

I bought this light because I have a 15 gallon cube tank for my glofish tetras and danios. Unfortunately, it's not at all designed to go onto a rimless tank. It took me a good half hour to find out a way to attach the light to the inside of the tank since it couldn't be attached to either the tank rim or the lid.

it’s ok, not for a 20 though

I bought this for my kids 10gallon and it barely lights it up, too many blue leds also. If you get this for the advertisement of 20 gallons, you would probably need 2. Planning on replacing it even for the 10 gallon.

Glofish Cycle Light

This light is awesome. Has three different cycles so there is three different color changes. Easy to install, just clips to tank. Makes your tank colors vivid and amazing. I highly recommend this light.

No way to mount ?!

Hello, I'm not sure what type of aquarium this light is suitable for, but not just "any". The directions show "how to place" light, and it literally is just levitating on the glass it seems? There is no way to stick it! No suction cups!Do I have to tape it?! So very frustrating. Also, it seems WAY too bright, for me and the turtle. If I were to "tape it".
