I am putting new substrate/soil in my tank and was hoping to get some assistance in order to not expose my fish to any rising levels of ammonia from soil.

This is a well-established 30 gallon tank that has been running for about 8 years, but I know, despite this, that I will experience a temporary mini-cycle from changing out substrate. This Im not concerned with--- it is the ammonia leeching for aquarium soil.

My question is: Is there a way that, once I return the fish, not to expose fish to leeching of ammonia?
Would daily water changes of 50%, for example, be enough ( *not sure for how long) to do this?

PS. The Soil is a 9L bag of Amazonia Light.

Try to put insert some Diatomaceous earth using a turkey baster into the soil but try to minimize it from the water column.
first wet the Diatomaceous earth in a container then only use the turkey baster to insert into the soil.
So what is purpose you may ask?
Once you have it you put it in it will be easy for the plants to grow because it will absorb all the fert and focus it so that all the plants will get equal and not less of the absorption of the fert thus balancing the tank.
