I would get the biggest pressurized CO2 system you can afford. A $50 unit does not sound reliable or adequate especially if you wish to keep something more sensitive like shrimp. I would suggest getting a pressurized unit with a solenoid, bubble counter, regulator, diffuser and tank. There are often good, used units on BCA. A paintball unit could also work. Just be mindful that filling a CO2 tank can be expensive depending on where you live (shop around).
If you are starting with brand new Amazonia, water changes are highly recommended IMHO.
My regime usually looks like:
Fill tank day 1, do 100% (or as much as you can) 12 hours post fill, then do the same amount 12 hours later.
Wait 24 hours, do 100% again.
Then wait 24 hours, do 100% again.
Wait 24 hours, do a 50% WC.
Then wait another 24 hours, and do another 50% again.
After that I would continue doing 50% WC every 3 days until your water parameters are in check.
