2x250 mh is more than enough
Update.
The tank has not cleared up. Still waiting!! I have learn't one thing from all of this. Always rinse your sand before adding it to the main tank. My tank is all milky. It has been 2 days and I can't see anything in the tank. I will be getting my live rock tomorrow and won't be able to aquascape. I have added sponges and powerheads but nothing is helping.
