Is it snowing?

I'm on the second dose of API Acc-clear and running surface skimmer, to be honest not made much difference.

What volume of water should I be removing, and how often, to help clear the mid tank floating particles?

I've had this happen before, but it has always cleared up in within a few hours.

Question: if you switch off your pumps and let the aquarium water settle, does it sink or float?

Turned off the filter, let the t water settle, particles floating not sinking to the bottom.

Tempted to use a fine net to get it out.

I tried the normal net I had, no success, I'll purchase a fine net and give that a go.

Before you do that. Put kitchen paper towel in the net, use clothes line pegs to hold in place and try again.

If you can't get it all, try Purigen, that's what I've used when I've had a similar problem.

Thanks for the advice, tried most of the suggestions, above, skimmer, acc-clear water changes, net and kitchen paper, turned filter off particles still floating around the tank.

White Particles are extremely light and very fine, can't be caught in a net, and just keep circulating around the tank, not really being caught by the intake pipe or skimmer.
Any further suggestions welcome.
Thanks in advance.

They move when filters off? They aren’t copepods are they?

[Flex365]

Not come across the word copepods before, just googled it, the particles just look like specs of white dust circulating around the tank, as per my original picture , so not sure how I'd be able to tell if copepods or not ?
