Need Help With Cherry Red Shrimp/fire Red Parameters

[fluffysfish]

Hello everyone new here. need help with my parameters in my guppy/cherry shrimp tank.

jan 29th, filled 10g aquarium with gravel water dechlorinated with prime.

jan 30th waited 30 hours added the big bottle of tetra safe start plus after shaking well. then added 2 guppies

feb 1st added 2 sterba corys.

feb 2nd added 20 cherry or fire cherry shrimp

feb 11 checked parameters and i see 2-4ppm ammonia and 40-60ppm of nitrates. performed 10-15% water change.

feb 12 checked parameters pictures below.

ph i would say 6.8 to 7
ammonia .5 to 1ppm ?
nitrite 0
nitrate 20-40?

is the cycle almost done? my fish and shrimps are doing fine. one of the cherries just gave birth to some shrimplets i still see them and everyone is eating. I purchased another bottle of tetra safe start plus just incase i need to dose again.
if cycling is not done is there anything i need to do in the mean time?

i also need help with future water changes. recently my tap has gone from 7.2 to 8.4. lfs told me to use seachum ph regulator to keep it at 7. to add during water changes to keep ph around 6.8 to 7.
please see below for tap water.
.5ppm ammonia
0 nitrite
0 nitrate

first photo is is feb 12 readings. and second is tap water

any help is appreciated thank you

Do not use any chemicals to alter pH.

Ride it out, keep ammonia low. The cycle is almost done.
