    Pondy smell..?

    i've noticed especially with the warmer weather that, and though not unpleasant.
    there is a definate 'pondy' smell around the pond especially when going into the filter house...
    a similar smell to when fishing around a lake...

    the missus commented on it, and in an effort to stave off any future ammunition against a bigger pond.
    I decided to put my 5 litre mesh bag of carbon in the filter...

    carbon is pretty good at most filtering but very good with odours....pondy smell is completely gone.
    in fact it smells so fresh in the filter house, i could market the smell as 'eau de koi'

    That's interesting to know.

    I have 5kg of it that I bought after you'd recommended it for another problem I was dealing with some Months back.

    My pond water has been tinted from the food I've been using, apparently activated carbon can deal with that too, although I've not tried yet.

    Covid 19 does quite nicely at preventing smells. Send the Mrs to Spain, then quarantine .. and bobs not your uncle - no ammo

    Wondering the same as you, Aggrowe. Noticed a bit of a pondy pong if I’m on the ground next to the water.

    What is carbon normally put in the pond for?

    i just used some Rowa activated carbon i had left over from my reef keeping days...

    but any aquatic activated carbon will do...
    though you get less dust to rinse out with carbon pellets rather than granular carbon.
    and a large fine mesh bag.

    it's not essential in a pond, and could get used up/blocked fairly quickly depending on how dirty the water is.
    but will adsorb organic compounds like tannins, odours, and pheromones that the fish excrete.
    plus ideally you want to push/pull the water through it in a container or cannister.

    i've got mine running through a mesh bag on the outflow from my filters to my header pond.

    not sure if id use it all the time, as you probably need a lot per gallon 2-5kg per 1000 gallons i seem to remember from somewhere..?
    but will also help mop up chemicals after treatments.
