Ok so how much of a water change per day do I need to do?
Do 20-25% water changes 2x a day until the ammonia doesn't register.
What test kit do I need to monitor the water if I add Prime?
Seachem's Multitest kits are best in these cases but a salicylate kit will work. You just need to be sure to take the reading immediately. You can read the
FAQ here...

How long does it take to knock down the ammonia and such? I have been in this for 3 years and I guess the most frustrating thing is there are so many theories as to how to do things. I have always heard that if you continue to do water changes, this only prolongs the cycle from completing.
As I said, as long as there is an ammonia source (fish in this case) the bacteria will be fed so don't worry about that part. Understanding how bacteria feed and expell waste is where people get led astray in these matters. In regards to cycling in general, water changes will only affect the cycle if you remove the food/nutrient sources. Limiting them does not prolong or deter it in any way. As long as there is even trace amounts of ammonia registering, there is a food source. Having larger amounts of ammonia does not make a tank cycle any better.
Look at it this way. If you cycle a tank via the fishless method, you reach a certain ammonia level, it subsides then the nitrite and nitrate. That's the basics of the nitrification. The one thing missed by many is the ammonia source is usually also depleted by this time. Bacteria grows to meet the food source provided. So in the long run, it doesn't matter how much ammonia/nutrient you start out with. By the time a biological is added to the system the level of nitrosomonas and nitrobacter has diminished some anyway and must again "grow" to meet the new deman and each waste producing animal added afterwards. It is not "always present" in the numbers needed until the food source is provided.
If you are cycling in essence a dead tank from scratch, no
LR or
LS, water changes would be pointless simpley because there's no need.
If using fresh or not fully cured rock I would highly recommend water changes. You would not be removing the nutrient simpley limiting it's levels. It does not impeded a proper cycle in any regard but you would be preserving the much desired hitchikers and bugs within the rock.
Also do I wash the
PVC off when it starts turning brown in the tank? Or do I leave it? Im afraid to do anything now.
Unless they are interfering with water quality, leave them be. A
QT has very limited surface areas so baterial realestate is at a premium. Unlike the sponge they are not really pourus and do not trap debris. The algae growing on them is somewhat a good sign. It means the biofilter is actually maturing.
