Am I almost finished? What do you think?

[missmonday]

Crazy cycle continues...! Looks like I'm getting closer to the end? I've been testing for a few days but still not sure what's up with my nitrate. The bottles expire in 2020 so they're not old!

Jan 31st
Am 1.0
Nitrite .25-.50
Nitrate 5.0

Feb 1st
Am .50-1.0
Nitrite 1.0-2.0
Nitrate 20

Feb 2
Am 0
Nitrite 2.0
Nitrate 40

Feb 4
Am 0
Nitrite 2.0
Nitrate 40

Feb 5
Am 0-.25
Nitrite .25
Nitrate 5-10

How do my nitrates fluctuate like that?? Since I started dosing seachem stability on the 31st, that seems to have helped a lot! My ph seems to be holding around 6.4, but I'll put in some crushed coral to help.

Any advice?
