Need Help On Shrimp Tank Cycling

I have set up a 1 ft tank which is 2.5 weeks ago. i am having ammonia reading of 2 - 4 for the past 1.5 weeks. the ammonia reading doesn't seems to drop unless i do a partial water change. Normally how long will it take for beneficial bacteria to build up and break the ammonia?

Filter: Spong Filter
Temperature: 27 degree - 28 degree
Ammonia: 2 - 4 ppm
Nitrite: 0
Nitrate: 0
PH - 6.3

there are some article stating that low ph will cause a slow building process of the beneficial bacteria. is it true?

What substrate area you using? Aquasoil or sand? With sponge filter, recommend water change is every other day. Canister filter with correct media will speed up the cycle. Bacteria starter will also speed up your cycle.

Yep, 30-50% water change to keep Ammonia at bay. Without canister filter, your tank will be fully cycle about 6 weeks or even more.

Ammonia is needed to establish beneficial bacteria. Then it goes through nitrification process. When Ammonia is high and your filter can't cope with it. Excess Ammonia need to be remove, WC help. If you don't want to remove, cycle period will be longer as your filter only able to cycle certain percent of the ammonia. Yes, it does help certain level.

The ammonia just needs water changes and a long cycle time; you can do a complete or large water change every week for as long as you cycle your tank. I believe a good amount of time to cycle aquasoil tank is a month, with canister filter

Everything, Nothing, Nothing, Everything

Your 2-4ppm of ammonia is great for cycling a tank. By the looks of your NO2/NO3 you're still in a very stage of cycling. I would suggest against any water change unless your ammonia goes over 5ppm at which level ammonia will actually start to kill the nitrifying bacteria.

If you don't change water, when your ammonia and nitrite (NO2) are at 0 ppm and you get a high reading on NO3, then do a 100% water change (preferably remineralized RO), let the tank run for another few days until PH is stabilized, then you are ready to add shrimps that requires soft and acidic water.
