Is Seachem Fert Series Safe...

[BruceII]

For Guppy Fry? Had a fish give birth today. Haven't wanted to to dose yet. Thanks for the help in advance!

I use Flourish twice a week in my two guppy tanks, with adults, juveniles, and fry. Primal is still actively producing a healthy amount of fry every month, and I have noticed no deaths or deformities.

It depends which of the fertiliser series you are using. Flourish Comprehensive Supplement for the Planted Aquarium is safe. But I would not use Flourish Excel in any tank with fish, fry or adults.
