Go ahead and tell us how big the tank is (either in gallons, or measure length, width and height in inches)
Find out what the wattage is on the hood your uncle is fixing. Corals need a lotta light..the regular light you have on there isn't enough for corals...if you have three of those bulbs, you'd be able to keep some shrooms
. You basically need at least 3 watts of light for every gallon of water the tank can hold, as a minimum lighting level. 5watts per gallon would be better.
