Can't Keep Corals??????

I have a 125g, 100lbs LR, 3 inch LS bed, protein skimmer, 3 1200 Maxijet PH's started in Oct. All fish have been QT'd before adding to the tank and no medication has ever been added. I never see any pods so I'm not sure if its actually live sand or not. Lights are 3 250W hqi de MH 13K and 2 140W VHOs. Lights are on 11-11 with the mh's on from 2-9. Ammo 0, nitrite and nitrate 0, ph 8.2, calcium 450. I add B-ionic once a week for calcium and alkilinity. Feed 1x day with frozen emerald entree and cyclopeeze. Twice a week krill, scallops, shrimp. I'm using distilled water for water changes and top offs once a week which I started about 3 weeks ago. My PH dropped to 7.8 last week probably for a few days when I was topping off with distilled water and didn't realize it. I'm now adding a marine buffer to keep the PH up. I have eggcrate for the top.
I had a bunch of coral that all died within a month because I had a PH fall into the sand bed 3 days in a row while I was at work creating a sandstorm for a few hours. I now have the PHs securely attached so I've had to start over.
I bought a elegance coral (didn't realize they were hard to begin with) and a green bubble coral that are both slowly dieing. I also have a white bubble coral which I had threw the sandstorms that isn't improving or getting better either. I also got a 3-4 inch rock of zoos 6 days ago and they haven't opened up yet. The elegance is in the sand. The bubbles are both about half way up the tank and the zoos are near the bottom.
Fish mates are: sailfin tang, blue tang, red firefish, purple firefish, 2 osc. clowns, six-line wrasse, 2 green chromis, bar goby and a foxface. I also have two brittle stars, a bunch of hermits, green emerald crabs and porcelin crabs, a bunch of peppermint shrimp and a cleaner shrimp.
What am I doing wrong? :help: :help: :help:

I thought I got everything. :D Salinity is 1.024. Temp is 80. I also have a bunch of snails. I only temp acclimated the bubbles but dripped the zoos for about an hour.

well now my mind is boggled????? you say you run lights for 11hrs. May sound nuts but i would cut back to 8hrs on since you are running some pretty powerful lights. thats my opinion, i'm not sure if corals can ever get too much light but 8 hours should be enough to keep them healthy. How often do you change your water?

Your mind is boggled???? Mine too! The VHO's run from 11 am to 11 pm. The MHs run from 2 to 9 which is only 7 hours. Should I cut back to 8 hours total and only run my MHs for 4 hours? I have to top off every 2 to 3 days and I've been doing water changes 1 a week.

Heres a quick off-topic lighting question, I'm recieving my Aqualight combo fixture with metal halides, moon light, and power compacts today. How long should I have each of them on? And from what times? Do I always have a light on? Like when the metal halide, PC are off, the moon lights are on?

What is your alkalinity? You are double dosing alkalinity buffer but don't post any alkalinity values.
IMO, your specific gravity is too low...do you test with a refractometer or hydrometer?
Are you keeping snails, hermits, shrimp, etc successfully?

I've had snails, starfish, crabs and shrimp fine since Oct. I test with a hydrometer. I test Alk with a Red Sea test that falls pretty much in the middle of normal and high. What do you mean by double dosing? With the B-Ionic? I'm using Tropic Marin salt. My temp is 80 with salinity at 1.024. What should it be?
