I just upgraded my PCs to a DE ReefoptixIII MH 250 watt with 14000k phoenix bulb. My question is how far should it be from the top? Right now I have it about 7-8" from my tank hanging from my ceiling. My tank is a 30 gallon 30" long 18" tru vu long. I'm thinking of having the light on for only 5 hours for the first 1.5 week. then gradually adding 1 hour per week until I reach 8 hours. Also, would I need a small fan for the heat? Any help will be appreciated. Thanks

A DE with glass can be however close you want. 3-4" imo. Moguls you have to keep 8-12" to keep them away from splashing because they can break. A better light acclimation would be starting your fixture up high 1.5' or abouts and slowly over 4-6 weeks lower it down to where you want it for best coverage.

 

Also, would I need a small fan for the heat? Any help will be appreciated.

Answer: Does your tank get hot?
