    Sad but true. Your contractor is trying to cure cancer with a band-aid. Exchanging Sand for Zeolite is a temporary aid that "may" extend your backwash frequency (if it is coarse enough), but only for a while.

    Here's the blunt truth of the matter.
    He doesn't know what he's doing. He's a swimming pool guy who thinks a Koi pond is nothing but a swimming pool for expensive fish. He's using pumps and filters designed for one purpose to perform a different function, and it is a very expensive way to still get it wrong.

    Thank you all for your input, much appreciated!
    The over the past day and half I have been running the system bypassing the sand filter and just through the bio filter, the water looks great in the daylight but when the pond lights are on you can see some floating algae although it’s not that bad.
    The algae on the side of the pond appear to be declining in places, notably around the skimmer area.
    Whilst this may be a silly question (remember I am new to this), why can’t I fill the sand filter with beads and have to bio filters running, would this solve my problem?

    If you cannot return the swimming pool sand filter:

    Can you convert YOUR sand filter to a bead filter? Yes and maybe.

    Will this solve your problems? Maybe.

    also while focus has been on the fliter also need to look at the pump.
    if filter is made for swimming i can only guess the pump is a high amperage pump like a swimming pool.
    check out the amps on that pump and get back with us ,as i am sure there will need to be a change of pump to get your electric bill down also.

    The pump is a 1.5 hp electricity HOG.
    Designed specifically for high pressure pool/spa use and a horrid fit for a 14000 liter pond.

    Do you know how much extra a 7.2 amp pump running 24/7 is going to add to your electric bill?
