Good that you were able to do a 12hour check. That shows that it still has a ways to go I believe. What day are you on overall? WD

 

[Skins]

Day 66 but then i did remove some of my media if you can remember.

Skins.

Your readings for that number of days sound very similar to many others I've watched in past years. WD

I would say that you need to be doing 12 hour tests to see where your n bacs are up to

Yes, going to tonight. Fingers crossed for very very very very low readings.

In your position I would dose at 24 hours and test for nitrite at 12 hours, I wouldn`t bother testing for ammonia

Just a suggestion but if your nitrate is still off scale I would reduce that with a big water change, you dont want high nitrate messing with the cycle at this late stage

Things can happen quickly at this stage in the cycle, looking back over my journal those annoying traces of nitrite disappeared after I reduced the nitrate
