can someone explain lighting to me

i dont understand what lighting is needed for anenomes or coral rite now i have fish only in my tank and would like to know more on what is needed for my tank

 

Can you tell us a bit more about you tank. Size, dimensions, filtration, etc. Lighting is only one factor with regards to corals.

Once we know more about the tank itself, identifying a nice lighting match will be possible.

 

Do yourself a favor and check out the article section on 3reef! There are a couple of articles, I believe, that should shed some light on the subject.
The type of coral you decide to go with also will have to be taken into consideration as well as placement.
Their is also a lighting section on the thread categories to help you as well as countless info on the world wide web and books by the likes of Borneman, Fenner, Sprung, Delbeek and Calfo to assist you as well.

 

31 tall 18 deep 4 ft long 120g i have a canister fillter protein skimmer and uv sterilizer i had a refuge hooked up but im takeing it out for one of the machines that gets rid of niterates i have 2 clown fish yellow tang hippo tang blue damsel tuxido damsel and some mollys

 

i would rather have anenomes in ther if there any diffrence for my clown fish to play in...

 

Two 250 or 400 watt halides should be fine

 

do i have to get a chiller also?

 

i wouldnt think so in a 120g. Evap. would cool your tank down, just dont forget about getting a reliable top off.

 

what is a top off

 

Top off is used to replenish water that has evaporated from a tank. It is always freshwater as when saltwater evaporates, the salt remains thus an increase in salinity.
As for the anemones, I wouldn't start experimenting with them until you have become a more mature aquarist!
Not to put you down or burst your bubble, it is just that they are somewhat demanding in terms of their requirements. Start off with zoanthids, or coralimorpharians, or even Xenia which may offer your clown a surrogate host.
