i foolishly unmounted my metal halide unit last night and left it unnatended in a room full of complete idiots....mainly myself. accidentaly it fell into my tank and the bulb shattered. i have no idea weahter the unit will work as it was half covered in salt water. im leaving it to dry out and am currently looking to buy a bulb for it. this is a rather confusing task as have looked arround and found many different variations. my unit is 250w i need to know what im looking for to keep a reef happy. i have anemones and an elephants ear, clove polyp, frag of xenia fer other bits but im building up my reef. what lumens would be best? what colour output?
