Lighting!!! Help!

yousefbassam123 · 08/25/2017, 03:10 PM

Hello, I have been looking ofr an answer to this question for so long, hopefully someone will give me the response I am looking for. My question is, some corals should be placed on the bottom of the tank and in the middle and some on the top. How can I know if they are getting enough light in their area? My aquarium is more vertical than horizontal. How can I tell if the coral is getting enough light or too much light? Is there a way to know?

Use a PAR meter to get a reading of PAR levels at various depths/spots..

They are usually a couple hundred dollars or you can rent ones from your local fish store sometimes..

They're too expensive, anyway I can tell by their behaviour?

It really depends on the coral and what light your using and the depth. You don't have to have a par meter. You can eyeball it but it might be better if you give us some more specifics about your setup.

All depends on the coral. Be more specific.

The starburst coral and the trumpet coral

It would also depend on the lights you are using and the actual dimensions of the tank.

There is a world of difference between the different types of lighting available and just what they can support.

More information please?

If you want to know the light levels you have in certain spots then a PAR meter is the solution..
Either that or watch your corals.. If they start to bleach (turn white) its too much light and they should be moved down lower..

No other way to know besides guessing as corals don't answer text messages nor emails and don't speak English either..
