RTing? or something else

Hey folks, Thank you for looking at my thread.
I am new to reef keeping and I am trying some SPS and others. I have a 120 gallon tank with a Little Giant 5 for water circulation. I do not yet have a skimmer.
For lights I have a 10,000K 400watt and a 20,000K 400watt lights next two each. This lights 2/3 of the tank. I have two 6 foot daylight high out put fluorescents.
The tank was purchased from an ad on this site in October. I threw out most of the crushed coral and replaced it with 3-4 inches of sand (I am now hearing other things about sand!). The tank included 120 pounds of live rock. It included two soft corals and I threw one out after I thought it died.
My water parameters are:
Nitrates 0
Alk 2.90 (I am having trouble keeping it up. I just need to dose more often. I think I will raise this level up like Eric Borneman suggests in his article this month on Reefkeeping.com)
Ca 390-420 (again I need to dose more often)
Phosphate I have not tested this. I suspect it may be on the high side since the tank was nutrient loaded when I got it. I have had a lot of hair algae. I have used one can of PhosBan by Two Little Fishes. This was developed by Julian Sprung. It appears to have helped. I have a second can but was advised to wait and see how the tank did with the new clam that I purchased. I plan to purchase a test kit the next trip to town too.
I have dosed yesterday with two capfuls of Mg (Kent marine).
I have dosed a month or so ago with iodine (after one of the cleaner shrimps died after molting and then dosed yesterday.)
Bioload:
I have no fish in this tank at this time.
I have two turbo snails.
A conch.
A nudbranch (green algae eating kind I was told. Not in Anthony's book either.)
A cleaner shrimp.
And finally a T. Crocea clam (4 or so inches)

I have tried three frags from Kevinpo in town. The first two were under 175 watt lights. (not sure of color spectrum). They both died. Then two weeks ago I added another frag from Kevin, a Montipora I believe (sp?). It was under the new 175 watt 10,000K bulb for about a week and then I upgraded to the 400watts. Kevin said to leave it in the same spot (8 inches under the water directly under the 10,000K). It did not last long before it turned white and the tissue peeled off.

I thought that I was burning the corals. So this week when I brought frags home from the Seattle meeting I placed them on the right side of the tank where they would receive light form the vhos and the 20,000K but not directly under it. Everything looks ok to me except the purple tip that came from the big black contain at the meeting. It looked good for a day and now you can see what it looks like.
I am not sure where to go from here. I plan to install a 1600 gal/hr pump today. I then plan to build a skimmer. The plate corals and Zoanthids seem to be doing fine. One has opened and the other has not. The candy cane (I think that is what it is called) has not opened that I have seen. I will try to post more pictures of all of these.
:(
Here are the pictures. Please correct any identification problems.
Thank you so much.
Joel

It is hard to say why your corals have been rtn'ing, but that coral in your picture above is not a SPS coral, but a green star polyp. They are really very hardy and are much less demanding then sps corals are

oh your pix changed! Now that coral in your first pic does look pretty bad, looks like it is pretty dead. The plate on the last one is a monti cap. and looks pretty healthy. I have found those to be a little more resilent then the acro's.

With the zoanthids in the last picture there it looks like they could use some more flow. I would blow them off directly in front of your return to help them sluff off all that waxy looking stuff on the bottom. Just hold it there for a couple minuits and then place them in a higher flow area

That is what I was thinking. I will try that. They are in a area that has a little less flow then the others. Will do right now. What about a higher light area?

My Zoanthids love the halides, they squinted their eyes for a couple days, but are now looking healthier overall then they ever did under VHO. I have some that are right at the waters surface on the back wall and seem to love the new lighting. Most of my zoa's are closer to the bottom of the tank tho. I run 250w 10k's

Hey Joel, the tank is still a little young and has some swings to still go through (bacteria/algal,and so on) SPS although just as easy to grow as most are a little touchy to swings of parameters. Your alk and cal are fine exactly where they are, so dont worry about bumping them up. What the temp like and salinity??

mojoreef,
Hey, good to hear from you.
My salinity - last I checked - hangs at 1.024. I have a automatic water replacement so long as I keep the bucket full. I do well with that so there have not been any drastic swings.
Temp - I don't have a controller for this and my home is heated with wood so the house temp can swing from 60-78 in the room with the tank. I have the heaters and fans on timer so I manage to keep the tank at 78-82. The alarms go off below 78 and at 82. I may buy a controller once summer hits.
Thanks for the advice. Like I said, I want to give it more time.
The thought just hit me. I have one remaining soft coral left. Could this have anything to do with it? It is quite small. It was on the rock when I brought it home.

Well, the only update is that they all died. I have the purple stuff(the poison one) and the candy cane coral are all fine. The candy cane is growing well.
I am going to get a skimmer going and then try again.

It looks like in the pics you have some water issues. Sps like really good, clean water. For sure you need a skimmer and a really good one. You need some phos remover and keep a close watch on when it needs changing. Are you using RO/DI water?, if not what is the tds reading of the water in spokane? You should have some carbon or resin on the system also. You can run more then one bag of phos remover, it just last longer that way. The corals surviving like turbid water is why they survived. You may need to vac that sand bed also. You have one of the best guys in kevin to help you, ask him questions and listen to what he says, he knows his stuff and there is no short cuts in this hobby, especially with sps corals.
