That's a good idea- if you've tried it, what's the performance impact? Applying modifiers to fluid meshes is usually pretty slow.

@@MrCheebs So firstly, I use the FLIPFluid add-on which I highly recommend getting when on sale if you like fluid sims like me, there are some overlaps with fluids in mataflow though but it has a lot of benefits. The modifier can be applied to the surface and is best when you want a more realistic ocean look, so maybe a large container of water which is rocking will produce some disturbance but the modifier will add that extra impact. here is a link that has some info on modifier advice it is not comprehensive but worth looking at, blendermarket.com/posts/flip-fluids-10-tips-to-improve-your-blender-workflow. I have not tried it myself however I always apply a smooth modifier to the mesh and It can take a minute to apply the settings but it does not seem to effect the play back speed much. It will be scene dependent but try it as it may increase render times but I am not 100%sure. Remember you can remove the modifier in the viewport once you know it looks good. you could renderer a test animation using matt colours for the water (with not particles) so see if the surface looks good. be careful, you don't want the displacement on the sides only on the surface, so a displace modifier locked in the z direction only could be more effective than the ocean modifier. keep up the great videos

If there’s another easy way to fix it, I don’t know it :/

I used a guide object that I animated to spin, but you could also use a vortex force object to get this effect.

@@MrCheebs I tried replicating the effect for a project I'm working on but couldn't get it to work right. Would really really appreciate if you could do a breakdown. :)
