Hi tien13378,
Cryptocoryne balansae is treated today as a variety of Cryptocoryne crispatula, called C. crispatula var. balansae. As far as I know, at the moment the botanists distinguish 7 varieties of C. crispatula:

But apparently there are also forms or populations of C. crispatula not well fitting in any of the described varieties.
I mean, the inflorescence of Your Crypt points to Cryptocoryne crispatula, compare with these photos:

But I agree, it's not the var. balansae.
Cryptocoryne albida is very close to C. crispatula, apparently some plants have very similar inflorescences:
