Prorocentrum Dinos

[Nigel35]

I got a positive Prorocentrum Dino confirmation and am in the process of beating them back. Oddly my corals have not suffered in any way? I've heard lots of information on defeating this particular dino. From one source I have heard that the addition of silicates actually causes dino populations to expand, while others have said adding silicates can deter their growth. Some clarity would be appreciated.

My nutrients are looking reasonable, although the system's nitrates would preferably be higher.
NO3: .5
PO4: .05

My only concern with solving this problem would be the addition of vibrant or other potentially harmful additives. I have had good success with growth and want to keep it that way. However the increase of beneficial bacteria and pod populations is a plausible option. I know there isn't a whole lot out there as to what organisms consume dinos but I would imagine that there is something out there that does?
I have found some interesting research on the cause and effects of prorocentrum and the effects the toxins have that is releases which some might find interesting.

Any and all comments are appreciated as always.

Dosing silicates will promote diatoms, which will outcompete dinos. That’s how I defeated prorocentrum the first time.

It didn’t work quite as well the second time. Vacuumed out the top layer of sand and rock surfaces twice a week for a couple of weeks, which had knocked them down significantly. I am still not dinos free, but getting there. They still hang around a little bit on the sand.
