metal haildes

My lighting has dual 150w hqi and 2 130w PC that are dual actinic. I need to replace the bulbs but was wondering.... Will this be enough for an anemone? I also wish to convert the PC to LEDs. Will the LED lights provide enough lighting for this. Tank is 100 gallon and 60" long

Hey I am purchasing a 40 LONG tank for a NEW reef tank build. I rushed into my last 40 breeder tank and in the end took it down so I could build one the RIGHT WAY, and take my time. My question is would MH lights be to strong for such a short tank? I believe the dimensions are 48 long 12.5 wide...

So, as our name states, we are broke college students with an unfortunate obsession with this expensive hobby. We're relatively new to it... Lots of experience with fresh/brackish water aquariums, but this is obviously a lot different. Anyhoo... New tank. It's been running since July and it's...

Hi I was wondering if anyone had any lighting suggestions for a 150 gallon reef system ( 48x24x30). I would like to use metal halide/ t5 H.O combo but am not sure of fixtures i could use. I dont have a canopy and plan on keeping all corals.

When I buy softies at my LFS where they run metal halides and take them home to my biocube29 with power compacts the mushrooms seem to shrivel up, the Zoas do fine, the yellow polyps do fine and the green star polyps do fine. So, I guess I'm only having a problem with 2 out of 2 mushrooms. Any...

I have put my metal halide on a timer that has them on from 7:00am to 6:00 pm. Is this too long? On the weekends I have to do 7:30-6:30. Could that length of time (11 hours) for the halides be causing my algae problems? I have 4 actnics on that same timing system. How long should they be on...

This maybe a dumb question but is it recommended to run a MH light only with no actincs or should you have the actincs.

I have a standard 75gal tank. I just purchased two (2) IceCap 250w Double-Ended HQI Metal Halide Pendant like seen below. I have Hamilton 14k bulbs in them. QUESTION: How many inches do I hang these off the waterline? so I get coral growth but not sooooo much light that I get into algae...
