I wouldn't say the OP is not heading our words. I suggested the instant bio thing as a way to help if it worked.
I know we have all been there, and unfortunately we all learn the hard way. I really have not yet met one person that has done it the right way the first time. Gazwas I think you should take back your animals and get the tank cycled. Everything in your tank might die and if somehow they live though it they will be permanently damaged. The primer is alright but it won't stop what is happening now. I think at this point it's too late!
Here is a list of everything you need to make sure your tank will be running perfect in the future.
First: If you can get everything out and back to the LFS
than do so!! Don't wait because this can be expensive to lose everything in your tank, and you more and likely not want to do Saltwater anymore.
Second: Live rock!!

This live rock will come uncured, but that's all right! Because you will have nothing in your tank and can cure it while cycling your tank. Mostly that just means the rock inside your tank will have die off, and things will start to grow. You can read many articles on how to cure your live rock. It's cheaper to cure your own live rock, and you can do it in a clean trashcan if you can't take your fish and coral back. Once it's cured you are almost good to go.
Third: Hydor Koralia Evolution Circulation Pump/Powerhead
Power heads, at least two for your tank. There is many different kinds of power heads and you need to find the right one for your tanks. This will help bring the coral's food and help in stopping dead spots in your tank. A good current is a must for the tank you are setting up.
Fourth: Lighting!! You need to get a least a strip of T5 lighting on a timer (timers are cheap) that can simulate a day and night cycle. There is many types of lighting and a light like this can get you some low light soft corals, but not much more. Getting into coral can be very expensive!! Lights can go all the way up to thousands of dollars!! I think I seen you already got your lighting, so that's good. :-p

Fifth: Protein Skimmers
A protein skimmer is very helpful in keeping waste down and your water clean. This can be a very good item to have and save you tons of trouble! (Don't skimp out on this, buy a good one)
Six: Heater, make sure you get a good heater if you don't already have one! You need to keep the water temp at the point your fish and corals needs it. Get a thermometer as well to keep in eye on your tank temp. I got two to help me keep an eye on the top and bottom of my tank. Thermometers are cheap and a necessary item!
seven: Filter, I know you already got a filter so you know how important that is.
I would get the live rock for sure!! It will look cooler when you have a tank filled up with live rock and it will help with the bio load. I Wish you the best of luck with your new tank and I hope that this set back will not deter you in the future. Most of the people on the threads here have done the same thing you have done, and have no room to talk. Sadly this is how most people get into the hobby and they quickly learn. So don't get discouraged! I know most people get into this because a friend or family member has a tank. Take your fish to your friends or family members established tank (If you have friends or family with a tank). Do the cycle right, you will be happier in the long run. Also if your canister already has a sponge, don't ever replace it!! If it does not have a sponge in a slot get one. A sponge in your filter will hold all the good bacteria for you for years to come. When you clean your filter DON'T CLEAN it with regular water. Use the tank water that you took out, and don't squeeze the sponge. Just kind of dip it into the bucket of tank water and swish it around to get lose stuff off it. A sponge only needs to be replaced when it is falling apart, and even than you need to place another sponge inside the filter to get it ready to take over.
I forgot an very important thing.
Get this!! Good test kit!
