Contaminated water?

I set up a 50 gallon corner tank about six months ago. Added about 30 pounds of live sand and some live rock. I have a 220 Marine canister filter, a pump with an airstone and a heater.
I let the tank cycle for about two months before adding any fish. I put in one Blue Damsel, one Percula Clown and some sort of a little crab to begin with. I waited about two weeks and added two Chromises and a Coral Banded Shrimp. Another week later I got a Chocolate Chip Starfish. Two weeks later one Rock Blennie and one Firefish. After approximately two more weeks I tried a Bicolor Angel.
Everything seemed fine for about three days, then I found the Bicolor laying on its side under a rock, not yet dead. I fished him out and took him back to the lfs, where she gave me credit for it. Waited about another week and and went back and got a Sailfin Tang. At that point everything seemed like it was okay.
I have to admit, I didn't do any research before I got into this and was relying on lfs to supply me with the information to get along. All of the water parameters tested good during the cycle (per the lfs). I have since gotten my own test kit, its aTetratest Laborett, is this a good brand? It test for pH, nitrate, ammonia, and KH. I also purchased a test kit for nitrates. I still need either a hydrometer or a refractometer.
After I replaced the Bicolor with the Sailfin Tang, I changed the carbon in the filter for the first time. Since then, and I'm not sure if this is coincidence or not, I have lost all of my fish except for the Firefish, the Blue Damsel, the Chocolate Chip, the crab and the Coral Banded Shrimp. These fish seem to be in good health, whereas the others showed some sign of being sick before they died. The last fish died about a week ago.
I really wish I had researched before diving in. I didn't know how sensitive salt water is and wasn't told. I'm a nailtech and when I placed my tank I put in the room where I do manicures, pedicures and acrylic nails. I think this is where the problem is. After talking to the lfs, I think the fumes, vapors and filings have contaminated the tank. I'm not sure, but it's possible I had lotion on my hands when they were in the tank. I have also burned candles in the room(can you see me hiding my face in shame?)
At the suggestion of the lfs I have bought Polyfilters to filter the impurities. I have used two filters in about two weeks and they seem to be taking longer to turn to grayish/black, two days now instead of one. I have been using 1/4 of the filter and wrapping it around the intake of the canisters filter (for ease of changing). I cringe to think what else I may have done wrong and am still doing wrong.
I know the polyfilter should go in the canister, but I didn't want to dismantle it as often as I think I would need to, as it is a royal pain to deal with. But I would be willing to if anyone thinks it would be in the tanks best intrest. My water parameters are: Nitrites 0, Ammonia 0, Nitrates 12.5 (lfs says this is acceptable, do you agree?), pH varies from maybe 8.0 to 8.4. Seems like I have to add Seachem Marine Buffer to the tank about once a week to keep the pH at 8.3 or 8.4. I have a hard time trusting my judgement on reading the color card on the pH. Temperature seems to stay steady at 79.
Last week I did two ten gallon water changes two days apart. Should I do more changes? Should I do more than ten gallons at a time? I think I've learned alot just from reading this board, and I'm sure i still have a lot left to learn. How long should it take for the Polyfilters to take the contaminants out of the tank.
The lfs that I deal with says that when I am doing nails I should cover any openings and the air pump with a wet cloth, while I am doing nails to help keep fumes and filings out of the water as well as keeping a Polyfilter in the canister at all times. She seems to think it won't be a problem to leave the tank in this room, what are your opinions? I would value any suggestions.
I plan on doing more reading, adding a skimmer and hopefully adding some more fish to a healthy tank somewhere in the near future. I'm in the process of purchasing the items I need for a qt tank, you sure can get a lot of money invested in this hobby! I've had a 30 gallon freshwater tank with no problems for four years, sure do wish sw was that easy.

Well Liz,
It is kind of hard to know where to start. I will start by saying WELCOME TO THE BOARD!
One thing that is good is that you understand that some things are not right. Research is the key to a successful SW tank.
Have you purchased any books? If not, I would certainly recommend that you get THE CONCIENTIOUS MARINE AQUARIAST by Robert M. Fenner. Great book with a better understanding of the entire hobby/business than many I have read.
Did you say that you still need to get a hydrometer?? How are you testing your salinity? This should have been the first thing purchased with your set-up.......just curious, if you are doing water changes.......how do you know what the salinity/specific gravity of your water is? GET A HYDROMETER.......preferably a glass one. Swing-arm style hydrometers are not very accurate.
You have many questions and a lot of times it is very hard for us to answer multiple questions in one post......I am having trouble right now. ;) It would be best if you could do searches for some of your basic questions and post more individualized questions that can be more easily answered.
I really don't know what to say about the tank being in an environment of such........I just don't think that it can be good. :(
I would definitely not add any more livestock to your tank until it stabilizes and you figure out what the problems are. We are here to help and don't hesitate to ask what you think might be stupid questions.........there is no such thing. Good luck. :)

Thanks for the welcome! I have been having the salinity checked at the lfs and they say it is good. I plan on purchasing a hydrometer very soon. Since I've been having problems, I've checked out several books from the library. I'm not finding a lot of information about contamination though. Is it possible that the Polyfilters will take care of whatever may have contaminated my tank or would I have more luck trying to change all of the water? If so all at once or large amounts over a period of time? I don't plan on buying anymore fish until this problem is corrected! Thanks for the support. Liz

Don't know much about your problem although I would suspect the water is contaminated. I don't know how to get rid of it, I would do water changes. I'm from Oklahoma too. What fish store are you going to? I have been to most in OKC and the only one I trust is Aquariums in Edmond. Anyway.....good luck!

I've been going to The Pet Place in South Oklahoma City. I've heard that Aquarium Concepts is good but is a little pricey How long have you done business with Aquariums? I feel like The Pet Place has been giving me good advice but I unknowingly failed to give details as to placement of tank and that it would be exposed to fumes and vapors...

What are you using the air pump for? Is it to add 02 to the tank or is it part of your filtration.
I would not suspect the nail stuff first. I would look for signs of diseases, parasites or a fungus on the fish. These can be spread from a sick fish to a healthy one in no time.
I would,
Add more rock for more filtration, Do a water change (again) Start adding fish slower. Allow more time in between fish and if possible, set up a quarintine tank for new fish to watch their behavior before adding them to the tank.
In a 50 gallon you will be limited to the size and amount of fih you can keep safely. A tang, well just my opinion here, will grow too large for your tank. Small pigmy angels are good for that size tank, but only after several months of it being setup and mature.
Go very slow when adding new tank inhabitants. This will allow time for your tank to adjust.
Good Luck and stick with it. It is a rewarding hobby but takes a while to get all the kinks worked out.

The LFS recommeded the airstone for extra oxygen. The Polyfilters that I'm using are going from white to dark gray in just a couple of days. Would this mean there is something in the tank that shouldn't be there? How much rock should I add at a time, considering there are fish in the tank? And should I be watching for the tank to cycle when I do? Thanks to all for the encouragement and support!

I thought all the fish had died? If you can get fully cured rock, you can add a couple pounds at a time. Uncured rock you do not want to add with inhabitants in your tank.
Cured= cycled
Un-Cured= raw, not cycled

I don't go to Aquarium Concepts....just Aquariums Tropical Fish and Supply (I think). I went to Aquarium Concepts once. They have absolutely no selection, thier prices are high for what they do have, and they have rude and uneducated sales people. I have been doing business with Aquariums for about 6 years. She's absolutely wonderful. Very helpful, knowledgable, everything is healthy, and her prices are reasonable. I don't think I've ever been to the Pet Place...is it in OKC or Norman? Anyway...good luck!
