Pretty much anything we add to the tank is going to have some effect on phosphate (it's in everything or so it seems, anyhow). I found that the biopellets also don't do a lot for me for PO4 reduction, although having said that, I think I read that they can only reduce PO4 alongside NO3. NO3 becomes the limiting factor, ie., once it's down to zero or near zero then the pellets can't reduce the PO4 any further than wherever they are at. So getting some GFO might not be a bad idea going forward.
Although if you're doing vodka isn't that supposed to take care of PO4 as well as NO3? I'm not really sure about that.
If you ran Chemiclean recently to take care of cyano, you might need to let that run its course before things completely settle out. I find it takes at least a week plus a water change or two plus new carbon to get a tank to settle back in after doing a cyano treatment.

I did have the mg at the high 1400 before but lately the tank demanded more and when it slipped down to 1250 did I started to raise the daily dosage. Could it be the drop in the mg creating the imbalance cause the red turf?
I used to dose VSV before running biopellets but I am only dosing vinegar along with the pellets. The no3 isn't too bad... Using the low range testing the no3 is at .02 (or so based on the colour chart). Not certain either if this had an effect on the po4...
I did the chemiclean back in early November so I am assuming that it may not be that. But I then jumped right into Zeozym two weeks later...
Guess I'll just work on the water change and see if the numbers will continue to drop or not...
