i had my tank set up for about 5 weeks and my ammonia level has still not spiked its at about .25. my freind had told me that i could actually add ammonia chloride to raise the ammonia level. has anyone done this or heard anything about it?

Yes, you can. It's not a safe practice because the difference between enough and too much is really tiny.
The ammonia does NOT have to spike for a good cycle, that's an unfortunate myth and had led to the downfall of many saltwater aquariums. 0.25ppm is perfect for growing the required bacteria.

Just wait until your ammonia drops to 0. How long has your ammonia been at 0.25? How are you cycling with live rock? What are you using for your filter?

Pretend you have a small Clownfish in the tank and feed a tiny amount of fish food every day.
How much live rock do you have in the tank?

I have cycled many tanks with ammonium chloride, but they were FO. With live rock in the tank, I would be reluctant to do it that way since ammonium levels can get pretty high, and it would kill off many of the critters that you paid so much to have in the rock. If you still want to try it, I have directions from Moe's book.

i have about 15 of live rock and 50 lbs of uncured. i have 2 chromis. i using a wet dry filter system as well in a 72 gallon. i just figured at this point the ammonia would have went up more thatn it has. algae has accumulated all over the tank as well.

the ammonia has been at .25 for about 3 weeks and i test every day and aloso put food in there everyday as well.

Are you using the Aquarium Pharaceuticals Ammonia test kit? If so it almost always reads 0.25 for ammonia.
Just continue as you are and let the tank mature in my opinion. If the ammonia starts to climb just do a water change to keep it low.

I'll echo the comment about Aquarium Pharmaceuticals ammonia test kits. They always look a bit like .25, even if you are testing completely clean water. In fact, as a control you could mix up a bit of fresh saltwate and test that. That will give you a true baseline color for comparison to the color you're getting from your tank.
Let's hope that your ammonia really is down to zero, for the sake of those fish you have in there!

From Moe, "The Marine Aquarium Handbook", 1992. Keep in mind that he advocates undergravel filters - it is an old book, but this procedure has worked for me in a variety of tanks. With lr the cycle may establish itself more quickly:
Use 6% ammonium chloride.
Day 1: Add 20 drops/10 gallons
Day 3: Add 20 drops/10 gallons
Day 5: Test ammonia. If below 2 ppm, add 20 drops/10 gallons. Skip dose if test not made.
Day 7: Add 20 drops/10 gallons if ammonia levels are below 2 ppm. Begin to test for nitrite levels.
Day 10: Nitrite levels should be at 5-10 ppm. Add 10 drops of ammonium chloride/10 gallons.
Day 30: By thi stime nitrites should have fallen to 3 ppm or less. If zero, begin to slowly introduce organisms. If not zero, wait up to another 10 days for levels to fall.

thanks for all the input at this point i still need the ammonia to spike before i do anything right? because it barely went up in 5 weeks.

Not really because if you have fish in there you have bacteria growing already. That's why you do a cycle before you add fish, so they don't have to suffer ammonia and nitrite spikes. Since you have fish, you're adding food, they're pooping away, poof! bacteria. Are you testing nitrites? How long have the fish been in there?

No, you do not need an ammonia spike. You just need to let the tank mature for a while.
