I have been searching through numerous articles on the war on algae. I have had a problem with algae for a while now. It seems like I take two steps forward and five back. So I ended up following the advice of the fantasy reef article and I think I have it under control for the most part but I have a question about my lighting. I have a 150w 14k Metal Halide light for a 30gal tank. DO you think that this light is to big for my tank. I have the HOB Viper HQI which also come with a 70 watt bulb. What would your suggestion be for lighting in my tank.

Thanks in advance
 
I have another quick question. Right now my aquarium does not have a powerhead in it. The only circulation in the tank is being provided by a hang on back filter and a hang on back protein skimmer. Would not having enough flow in the tank create a better opportunity for algae to grow? Thanks for any advice.
 
I dont think it`s too much. How long are they on during each day? Another problem is when they talk about lighting they are talking about older lighting. The older a bulb goes it`s spectrum will shift causing algea to feed off the different spectrum. If for example my VHO`s are supposed to be changed every 6-9 months and I wait and still have the same bulbs in there after 1 1/2 yrs then the bulbs are too old and have probably had the spectrum shifted. JMO. You keep using that FR formula and you`ll be OK on the nuisance algea.
 
I ordered a Koralia one and should hopefully get it middle of next week. I definately think that I have a lack of water movement.
 
Your lighting is fine for that tank, watch your water temp. What kind of corals in your tank? I would definately say you need more flow
