    do you need to clean pond liner

    a newbi question, my pond has a ledge 16" below water level, I have noticed that there are large patches around the ledge where it has turned brown I don't know if it is algae or crap but it is around the whole pond ledge, the pond has a roof and is not exposed to direct sunlight, I am thinking should I get a broom and give it a clean, i took a few pics on the mobile but unfortunately i left the mobile at home, will upload pics tomorrow.

    Sounds like silt/waste. Just sweep it toward your inlet. But this will happen all over the pond so I wouldn't get too up on it. Unless you have A LOT of spare time and OCD.... Ha ha

    So long as it’s not a thick layer, it’s biofilm and I would leave it alone, it will help with your bio filtration.
    If it is thick (=mulm) then it’s preferable to remove with a pond vac to avoid sending it into suspension in the pond water where it will just settle on other stuff. If it got really deep then could potentially harbour bad bacteria and parasites.

    at the moment it looks a very thin layer and in patches only on the ledge, i will leave it alone as you say, i have been enjoying the pond last few weeks with no water problem, no need to mess around, thank you

    If it gets to thick. As said harbours parasite.
    Pond vac as feline says.

    Agree with all above.
    Having kept various indoor tanks for approaching 40 yrs I was very used to spotless front glass and clean sides.
    Ive had several natural ponds over the decades 20 to 30,000gal with koi and goldfish carp orfe tench etc where clarity and parameters were all natural and biggest problems were things i faced were Mink.
    I had never dealt with an fully maintained artificial koi pond that I wanted aquarium clear.
    It took me a while to realise, but dont touch the stuff growing on liner.
    If it gets long cut back feeds and the koi eat it.
    I scrubbed mine twice near spotless like the fishtanks early on, then after the second time when my improving readings went down the pipe I had a Homer Simpson "Doh".
    Its all working for you in the pond, as the others say deal with the stuff you can waft off the bottom but the stuff that's stuck on leave it. My liner was black and now has a lovely mat black brownish green fuzzy slippery coating, any a few 2mm tufty bits, the fish eat off the walls all the time
    The photo attached is through c50 in of water to the bottom, its like tidy well maintained field to me and remember its very busy consuming ammonia etc.
    Plain English Mulm = "wafty stuff" aka debris/ food/ koi crap. Get it out, leave the rest.
    Regards,

    Homer S
