ALOT of low numbers during fallow :( need some advice.

Bacteria will be fine. But people go haring off after nitrates all the time under the belief that they are 'too low'. All that trying to raise them will do is make the algae grow faster. Sounds like your also about to go off chasing a bunch of other numbers too when stability is far more important to keeping coral than the exact number. Do this:

1) Do a water change.
2) Measure Calcium/Magnesium/Alk.
3) Wait a week.
4) Measure again.

The difference is your weekly dose. Dose that and don't worry about hitting some target number, only worry about replacing what's used up.

I am not chasing a certain number on these parameters just trying to keep them within the ranges that are considered "good" from what I know calcium below 400 isn't ideal and alkalinity below 8 is not ideal. If I could keep calc somewhere above 400 and lower than 500 I am happy. Same thing with alkalinity between 8-12 so not really chasing a specific number rather than just a "range". The more stable I have alk the more stable my PH will be.
