Is this normal?

[JDogg]

just finished a 3 day blackout to, hopefully, kill off blue-green algae.

just took off the cover and tested my water, pwc to come soon.

everything is "normal"
ph 8.0
nitrite 0
nitrate 20
phosphate 2
temp 78

but....
my ammonia, which has been zero for over a year is now at .25, not huge, but should i be worried?

it is my 28 planted tank in my sig...

plants look real good for no photosynthesis for 3 days!!! just a couple of leaves that need trimming!

Normal after a blackout. The bga is rotting, producing ammonia. Also, the plants haven't been sucking up nitrogen. The pwc will help.
