water readings crazy(fishless cycle)

I done a second wc in 3 days to bring up my ph and drop nitrites to get a better reading..yesterday did the 2nd wc redosed my ammonia back to 2-3ppm..did my readings this morning..seems my tank is going crazy..did my test before wc ...P.S...i do all my tests..just a habit

before wc
ph....7.6
high ph....7.4ppm
ammonia...3.0ppm
nitrite.......5.0ppm
nitrite ......80ppm

after wc(15hrs later)

ph...7.2
high ph...?...between 7.2-7.4
ammonia...0ppm
nitrite.......5.0ppm
nitrates.....0ppm

Keep adding ammonia to the tank!
You're at the point where the ammonia eating bacteria are pretty well established. Now you just gotta wait for the nitrite-eaters to establish better. You have some since nitrates are appearing, but not enough I believe. Seems pretty normal to me, at least.
For me, by this point the cycle was complete within a few days.

This is a cycle on a 20 gallon tank that is 3 weeks old. As you can see the ammonia is gone, but the Nitrites and Nitrates are still high. Should be about 2-3 more weeks at the current speed unless I add bacteria to the tank.

First, your one test is inaccurate - there is no way a partial water change will reduce 80ppm nitrates to zero.

It appears (as already mentioned) that the nitrosomonas bacteria colony processing ammonia into nitrites is well under way, but the nitrobacter colony to convert nitrites into nitrates has yet to form.

Just continue to be patient. Be sure to keep adding a slight ammonia source and continue water changes to keep nitrites and nitrates low. Nitrites are very toxic...even to nitrobacter bacteria. the colony development will be inhibitted if levels are not kept low.
