A potential control on
Ostreopsis dinoflagellates.
I keep reading published papers from scientists and today I found something interesting written by A. ISMAEL and Y. HALIM from Alexandria in Egypt.
They found a link between ocean temperatures and Ostreopsis cell count. Being the highest at 28°C.
This is low risk and very easy to try out, but the effect could be indirect and delayed so adjust your tanks temperature very slowly over weeks or months.
Their data it clear, but I'd expect a reduction rather than a cure.
I've tried various temperatures before without any noticeable results, but may have not kept it going long enough.
If i'ts Ostreopsis, you have to take a look.
Here is the original paper.
