If its a sand substrate your using it will take a while to settle with a filter pumping, don't worry about the spiking when you see the ammonia don't just water change straight away or its going to prolong the cycle you need to give the bacteria a chance but if it gets to 1ppm then your going to want to do a 50% water change, you need to get some "tetra safe start with live bacteria" its the best I have used for getting tanks going and I have to ask are you using declinator ?

When I change the water yes that was before TSS. Says not to use once you add TSS. And 1ppm total, I've been reading that you don't change water until 3 or 4 ppm total ammonia, and to add live good bacteria as you ammonia goes up to cycle faster and lower ammonia, as changing water makes it take longer. Is this true?
AAAAAAAAAAAAAGGGGGGGGGGGGGGGGGHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Right, hopefully that got both of your attention! And anyone else who's reading this.
Any ammonia is harmful to fish. When you get to 1ppm, it's potentially lethal, let alone 3-4ppm. Ammonia burns the gills, damaging them, and therefore limiting their capacity for taking in oxygen. For prolonged periods of exposure, this damage is permanent. Once the ammonia enters the body, it burns the internals of the fish too, and damaging them. Rather like human smoking, that damage isn't always obvious straight away, it can take a while to manifest itself.
The aim of any fish-in cycle (whether you are using TSS or Dr.Tims, or nothing) is to grow filter bacteria
without damaging fish. Therefore you need to keep your ammonia (and nitrite) down below 0.25ppm at ALL times. That means testing water everyday, and usually changing water.
If you test water, and see a level of up to 0.5ppm of either ammonia or nitrite, change 75% of the water. If you see between 0.5 and 1ppm, change 90% of the water. Anything over 1ppm, do muiltiple water changes of 90% so that you don't see a reading when you test again. If you see 0ppm for either ammonia or nitrite, don't change any water.
In a standard fish-in cycle, initially you will be changing water every day, but as time goes on and the bacterial colonies grow, you will find a day when you don't have to - but you will the next day. And then you can go 2 days. And then 3, 4, 5. Once you can go 7 days without changing water, then your filter is cycled - you can then go to a weekly maintenance schedule of weekly water changes, bearing in mind that if you increase the bioload (ie add more fish) the bacteria will have to grow to accommodate the increased ammonia, so you may have to do more daily water changes whilst the bacteria play catch-up.
What TSS, Dr.Tim's and the myriad other Bacteria-In-A-Bottle products aim to do is to decrease the time it takes for the bacteria to grow. Many of these products don't seem to work. There are some reliable claims that TSS and Dr.Tim's do work, if you follow the instructions correctly. I've never used either, so I'm not going to comment, but ultimately, you still have to keep the ammonia down to a maximum of 0.25ppm.
To answer Ky's point about having to give the bacteria a chance, a filter WILL cycle at ammonia levels that are not readable by our hobbyists' test kits.
To answer Brian's query about whether a cycle would take longer if you keep the ammonia down, well, yes it will. BUT, and this is the main point, the fish won't die. The fish won't be sitting in a pool of toxic fluid the whole time. Go sniff a bottle of household ammonia, trust me you'll only do it once. So, you can tell from doing so that ammonia is pretty vile stuff. So don't insist upon your fish having to respirate in this stuff. Please.
Just to fill out the whole picture for you, let's just touch upon nitrite as well. Nitrite poisoning is also called Brown Blood Disease because, guess what, it turns the blood brown. What it does is to attach itself to the haemoglobin in the fish's blood, and prevent it from carrying oxygen - it's oxygen which turns blood the red colour. What it means for the fish, obviously, is that it suffocates them. So keeping levels of this poison down is also a very good idea.
