Answer 1

The lights have nothing to do with it, any lights you buy from the petstore for your tank are good for them
Did you check your ammonia levels? Ammonia makes water cloudy
Do you change your filter cartridges regularly? you need to do so once a month
Are you feeding your fish to much?

There is no problem with the lights or filter,you have a bacteria "bloom" going on,and they are just too small for the filter to remove. The water will clear when the bacteria run out of nutrients,this may take 4 or 5 weeks. In the meantime just do your weekly 25% water changes and vacuum the gravel with a good siphon device. Be patient and do the water changes regularly.
