Firstly, in a tank that size, unfiltered
you are looking at 1 50% AND 1 100% per WEEK. A 20-30% weekly water change is only for tanks that are larger sized, cycled and that have many live plants. A moss ball isn't really going to make a difference, not nearly enough to do what you are recommending.
The 1 50% and 1 100% is what is needed in any tank below 5 gallons, unfiltered. And that will provide the correct water quality without getting too dirty, nor be too clean.
Secondly, ghost shrimps need oxygen, and generally a cycled tank.. or one with lots of live plants for them to eat on and hide in. Honestly, your tank does not have adequate shelter/food source for them, to keep them healthy and alive.. would highly suggest getting a filter and live plants if you wish to continue with ghost shrimp. They do better in larger colonies, but your tank isn't large enough for such to happen.
Highly suggest making it a NPT before wanting to add in more shrimp.
The shells will cause the water to become harder, not to mention, depending upon where they came from, can leach out salts and other chemicals into the tank. Ideally, it isn't wise to put sea shells into a fresh water aquarium. The fluctuation of pH which those could cause during the water changes can make it dangerous.
Didn't mean to harp- but wanted to make sure you got the correct information.
