Is my light strong enough?

[namlessdude]

How do I know if my light is strong enough? Is there a simple guide i can learn from?

My tank is a 37 gallon with 2 clowns, 1 tang, and GSP (attached is a pic).

Is the light i currently have strong enough?

Renting, buying or borrowing a PAR meter is the best way to know.

What is the brand of light? It's probably not a reef light for coral.

Tang has no business being in a tiny tank like that either and will die soon most likely.

The light name? If you search here with the name, or on line you might find a spectral output diagram that would help you/us guess if the light has enough Par as @Dread Pirate Dave suggested.

Otherwise, since GSP is ok in lower light and the fishes don't need light to live I think you will be ok.

If the GSP doesn't thrive then my guess were wrong.

But the dead tang will raise nutrients that can help the coral?

I don't think PETA will give a thumbs up.

Look at your wattage. Most of these lights are 30-40 watt and you want at least 85 - 125. Most decent China lights are 165wt such as vivarspectra
