I would say yes, adding any type of organics will up your nutrient leveks

I was wondering if they may actually reduce nitrates via photosynthesis?
Unless the bottled phytoplankton is already dead...
Did you read the thread posted by @boacvh

They do sell both bottled dead and live phyto, but depending on where you get it even alot of the live stuff is dead... You need a fresh bottle from a live culture, not something that's been on a shelf for 2 weeks

My tank runs pretty low nutrients.
Nitrates. .25ppm
Phosphates. .02ppm

I've been dosing both live and dead phyto every other day and so far, no measurable affect on nutrient levels.

I feed AB+ and phyto together every other day.

If anything, my phosphates are dropping, not rising. A couple weeks ago my phosphates were reading .03, but currently have been reading .02. (Hanna ULR)

Our tank is still pretty green and I am feeding Reefroids to keep the nitrates up. I started dosing live phyto to feed the copepods and the nitrates fell to zero within the week. I stopped the phyto and the nitrates went back up. I am currently trying to find the right balance.

Yes, have not got through all of it yet, but this is exactly what I was looking for.

In my opinion, yes, adding phytoplankton on a daily basis will mop up nutrients. In addition, I noticed an abundance of copepods (as evidenced by populations I could see on the viewing pane of the DT.) Some corals, such as Goniopora. suffered when phyto additions were reduced.
