Practically perfect in every way
yeah aqua soil does lower your ph, Ian has it in his planted tank.
however when you first put it in it gives off massivley toxic quantities of ammonia for the first couple of weeks so if you wanted to do that you'd need to set up another tank for the fish with a mature filter, put them in there, change your substrate then do water changes every other day and keep testing the water until ammonia hits 0, then put the fish back in.
also as it's a nutrient rich substrate you'd quite possibly find that without extra lighting and Co2 on the tank you'd get a massive algae bloom.
