bacterial bloom in breeding tank

[Ana6]

I have a male betta in a newly set-up 15 g breeding tank. It has a sponge filter which I ran in an established aquarium and transferred over. Maybe not long enough.

The tank has a bacterial bloom.

Should I wait it out for a few days, or start over?

Thanks.

i wouldnt, i would let it ride out, just do extra water changes to make sure the ammonia doesn't get to a high level. it will establish itself , new tanks usually get blooms.

You shouldn't place a filter before the fry are free swimming.
Male bettas might find the filter disturbing and not want to breed. Plus it disturbs the eggs in the nest and the fry.
Also, with doing minimum 50% daily water changes there's no need for a cycled sponge filter.
