Change lights and alk use when nuts.

So I went from 4 165w black boxes to 3 hydra 64HD and now my alk has been dropping 3/4 of a dkh per day. All my sps are growing new tips or entrusting even using a calcium reactor my alk is not staying in check have bumped up effluent up to almost a slow stream doubling my rate. Could lights really have this much of an impact?

Yes - if light was a limited factor for growth before- It looks like a classic example of this in your case.
