can this unit be placed inside canopy above glass top 4 inch above water and not hurt fish or corals on lowest setting

The focusing lenses require that the units be 12" or higher over the water, I have 2 of these on my 90 gallon, and they are about 18" over the water on full power. They put out around 500 watts of light so be careful! I tried them closer to the water on 1/2 intensity, ended up burning my corals a bit. Also. there are a couple of corals that didn't like them, pulsating zenia, and red colored polyps. My trumpet coral, frogspawn,and catspaw corals, along with green dragon eye polyps are doing excellent! Hope this helps you! Also, purple calcerous algae is spreading like wildfire!

You would need a stronger lite for a tank that size of you wish to have corals . Fish only might be ok

I would advise against it. It gets pretty hot and could warm your water more than you want it to. Also if you have any tall plants in your tank it could burn them. I'd suggest using the legs or at least hanging it just to let some of the heat escape. A glass cover doesn't hurt as well.

Probably unless you set it at the maximum height. However consider adding floating plants. They are one of the secrets to maintaining water quality, especially in a small tank. They will filter the light to the rest of the tank and filter many of the excess nutrients and waste products. I have them in all my tanks and weed them out regularly. Please dispose of them properly to not contaminate local waterways.

I have one mounted concealed from view in the filter/pump compartment of a Fluval Spec III (2.6 gal) and it works flawlessly. Should be fine in a 4 gallon. It's large, but it's flat.

Must be filled to the top (glass cover only), otherwise the filter pump will not have enough power to lift the water into the filter media. You can leave probably up to an inch below the glass cover if you want to, but you are risking filter failure and fish death due to lack of oxygenation (it happened to me...).

yes. that's how I setup for this skimmer. you may move your tank from the wall at least 4 to 5 inches to set the skimmer though.

You have to place the ozone 5 feet away from your pool. I'm putting mine on a 4x4 mounting it 1 foot above water level. Also I'm making a box for it so it want be in the direct sunlight. Haven't had the chance yet to put it up. Good Luck.

i use it sitting on a glass top. my tank is a 20 long so it is hard to open the cover with the light sitting on it. light itself is great.

You can actually place this filter completely under water. Without knowing what type of tank (bowl vs. rectangle) I would suggest putting this almost on the bottom of your tank and direct the flow somewhat against the glass to cause a current. If placed correctly the waste should make its way toward the filter.If none of that answered your question, I apologize, I have not kept goldfish since I was in elementary school.

I too am using a wood canopy on my 55 gallon tank to keep cats out. The light works perfectly. It only stands maybe 1 - 2 inches above the tank, and it produces very little heat, so that is also another plus.

Yes you can. We bought this item for our 55 gallon tank without a glass top and the water mist has no effect on the LED lights. We love it Jamie

The light unit is as long as the aquarium that it sits on. The canopy would have to be a couple of inches wider than the tank or you would have to buy a unit that is shorter than the tank it will be used on so that it will fit in the canopy. Also there is no way to hang the light. It is designed to sit on top of the aquarium its self

36" or some plants will not grow well and the tank will be unevenly lit. You always want it pretty close to the tank length if you are using plants with your fish. My tanks have plants everywhere because I give them light and it not even very bright either.

The screen and its frame are made of metal. The screening itself is rigid and fairly sturdy, not like window screening. So long as the lighting fixture is not excessively heavy, putting a lighting fixture on top of the screen should be fine. Make sure you allow adequate space for air to circulate and heat to escape, and make sure you allow the lizards within to have a heat gradient so they can choose whether they want a cooler portion of the tank or a warmer portion to thermoregulate.

This is a terrarium, not an aquarium. I do not believe it was built to keep water in it. I have not tried it. It may be able to do it. It may need silicon applied to the corners to make it water tight. But to answer the question how high it is, I am not at home right now, and my guess is: it is about 9in high.

The light would work sitting on the glass. I bought this light for my friend's tanks a while back. If I remember correctly it has a clear plastic cover that protected the lights, so the cover would act as if it was up against the glass any way.
