hqi metal halides

Im about to pick up a 125g tank and want to use the lights from my 120g. Obviously the problem is that the lights are 48" and the new tank is 72" long. I have 2x 250 HQI Metal Halides, and 4x96 actinics I was thinking that since the 125 isnt as deep as the 24" deep 120 that I could raise the...

This fixture is 48" long, has 2-250 watt HQI metal halides (2-14k phoenix bulbs with 2 to 3 months of use, and 2-10k coralife bulbs with 4 months of use thrown it) and 2-96 watt power compact actinics with 6 to 7 months of use. This fixture was bought about 10 months ago with 12 hours per day...

Picked up this sps for a really decent price. It looked metalic green under the lights at the lfs. Now, its kinda brown.:bawling: During the day he is so brown, his polyps especially. Will this guy color up? Is this just something sps go through when they get stressed?

How annoying this is. Within the last 2 weeks I have had a field of caulerpa and cheato grow on my LR. It just keeps growing and growing and growing. I try to keep up with trimming it back, but nothing seems to work at all. It is overtaking the entire back section of the rock in my tank.

Hi all, When I had to go to Crawford Long ER for my daughter (she is alright don't worry), I saw one of the biggest clam that I ever saw!! Overthere they have 2 aquariums that are like one big aquarium separated in half. One side is freshwater and the other side is a reef. I would say that each...

I got a frag of xenia from my LFS. It did great for two weeks. Yesterday I noticed a lesion on one of the four stocks. This morning, two of the stocks had them, and one was ripping apart at the now gaping hole. Now, in just a period of 24 hours, they went from looking great to almost completely...

I recently purchased a new light fixture with 2x150watt 10,000K HQI metal halides and 2x96watt true blue compact fluorescents for my 72 gallon tank. I leave the actinics on for 12 hours, and I used to keep my 10,000K compacts on for 10 hours a day, but now that I have HQI's, how long should I...

Hi All, I recently managed to exterminate all the wee beasties in my tank by accidentally introducing an inordinate amount of calcium for my corals. Sooo... what's my reaction to my loss? I've decided I need a bigger tank :-) I decided to start with a 29 gallon reef (on the small side I know)...
