    Hi I have a 5200 gallon pond running off two nexus 320 gravity fed filters, 2 drains, 2 x 20000 varipumps, 2 evo 110 uv, the water clarity is poor and full of green particles. Running pumps at 40% any advice?

    A few questions from me, is it lined or glassed, does each Nexus run off each bottom drain, and do you have a skimmer on the pond too... and When you say poor, is it just lots of particles in mainly clear water or is it cloudy too ??

    The draco is a mechanical water cleaner only but what is suggested here is a failure in biological filtration. Are Nexus 320 not able to do mechanical as well.

    Nexus doesn’t really filter fines, I ran them for years before changing to a drum.
    i used to run a bead filter after my nexus to take these out and it worked very well for a many years.
    bead filters can be pick up for very good price, and easy to clean/flush.
    the other option would be as Fred says drop a draco drum in one of the nexus see if that sorts it.

    Are you sure you have the correct amount of Micro K1 in the easy's ?
    I know Nexus can be lacking in fine filtration
