what would be the best light for mushroom coral need the name of the light
Mushroom polyps aren't very demanding in terms of light. Standard T5 fluorescents should suffice.
Should be fine. May have to change your hood if it does not support that light bulb type.
mushrooms tend to be low light but you still need at least power compact lighting at least.
You can use a low to medium light such as coral life or if you have a twin bulb fixture you can run coral life and a moon light bulb. Corals due best in a low to medium light environment and not so good in a bright light tank. The bulbs that I would recommend is Blue Actinic and a 10,000 k. Both these bulb can be used with a 40 watt bulb fixture.
