400 watt radium too much for 40 gallon high?
i have a 40 gallon high (36 x 13 x 20) with a 4" dsb... i love the radium look and am looking into getting a single 400 watt hqi with spider light reflector for the tank... i figure i'll have a 10" high hood... i'm just wondering if this is too much light for the tank...
i'm a beginner and don't plan on doing sps for a while but this is definitely in my plans for the future... i plan on adding a leather and a mushroom soon and would they not like the amount of light? thanks
