changing from CC to LS

[segsig]

I want to thank everyone that helped, especially Jmick in advising on changing my 55g from CC to LS on Saturday. It was a real pain and it went better than I had expected--even with cleaning off most of the massive green algae, as all my fish were still alive and kicking when I woke up Sunday morning. Now, should I expect a spike anytime soon due to the change or should it stay where it is as I removed all the water and put back approximately 30g of my water, and a combination of other prepared waters. My readings Sunday morning were.. like I said, maybe a bit high but better than expected for a novice such as myself........
PH-7.8-8.0
ammon-0.25
nitrates-20
nitrites-0
salinity-1.020-1.021
phosphates-0.5
fish are...
1 clown beauty
2 firefish
1 clownfish
1 goby

anyone??
I just went through the same process this past weekend. My readings are exactly the same as segsig's and I need to know if I should expect a spike in anything. Is my tank going to cycle again. My tank has been set up for over 2 years. I used half LS and put 3 basebal sive nylons full of old CC in my sand bed to help seed the new stuff.
Should I have any worries????
Thanks!
