    Looks bacterial to me,you say gravity filters but what sort and what is in them?

    They need a very good clean out,do they smell at all?
    Dirty filters breed bad bacteria mate.
    So you have a bottom drain?

    K1 media and then a set of foam pads in each filter

    No bottom drain but tbf there is never much crap at the bottom, the water is clear and the bottom is very visible to see any crap

    It’s the last month that this issue seams to have appeared

    Hi

    Me again - I've kept koi now for 20+ years and I decided to get back into it after a break of some 4 years due to work commitments - so....

    Your problems could have started with the size fish you stocked - when I started my pond twelve months ago I stocked with 6 x 1 inch fish and then added a 2 inch Chagoi and he's caught up to the others in 6 months- they are all approx 6 inch long now, one thing with koi is feed them and they will grow!! I had the problem with fungus on a fish'e pectoral fin due to it being stressed when moved from the shop and into my new pond as even though the temps were the same - the water parameters will always differ - he's great now and hopefully sorted - I won't introduce new fish now just let them grow to their full potential.- introducing new fish can be a nightmare

    Your fish are big fish and if you stocked them all at 5 to 15 inch in one go then your filters just won't be up to it and thus the water problems could have stressed the fish and reduce their immune systems. I've been told that a filter can take years to get up to running levels - the problem as said in earlier posts might be just too many Koi and a new filter - you could try one of those filter bombs that's supposed to accelerate the filter to maturity, but I would say too many koi too soon, keep an eye on your KH as this is the best water check and will give you an idea of the other parameters and remember that bacteria need carbon to build their skeletal outer shells and multiply

    If you research our hobby it's about looking after the water and when this is good the fish will take care of themselves

    Good luck

    Kev

    Scotty, I’m sorry if this sounds brutal but your ponds, whilst they look great, are simply not suitable for the type and number of fish that you have. Your current problems are almost certainly a direct result of that. As a very general rule:

    Koi - require 250 gallons of well filtered and maintained water per fish; a higher stocking density is possible but requires excellent filtration and maintenance; as KevT said, 1,000 gallons is really the starting point for any koi pond.

    Grass Carp - grow faster and larger than koi, so require at least the same as, ideally more, pond volume, etc, that koi require; see https://en.m.wikipedia.org/wiki/Grass_carp

    Sterlet/Sturgeon - Sterlet require a minimum of 1,000 gallons of well filtered, maintained and highly oxygenated water, ideally 2x - 3x that; Sturgeon require at least double that dependant on species; if you really do have a White Sturgeon (or is it an albino sterlet??), then they, it’s said, require 15,000 gallons; see www.pond-life.me.uk/sturgeon/sturgeonguide and Pond keepers guide to sturgeons: Sturgeon Web: a guide to keeping sturgeons and sterlets in garden ponds

    The best and kindest thing you could do is get your fish healthy and then move them on to suitable homes, either retaining at most 2 - 3 koi or, better still, re-stocking with goldfish. If you don’t do this, nature will ‘thin out your herd’ for you, which will be heartbreaking.

    Your water may be clear but that’s no guarantee that it’s healthy. Yours isn’t. I can’t tell what your pH or ammonia readings are (I don’t use test strips), but your nitrite appears to be between 0.5 and 1.0 - it should be zero. You can correct this with water changes and the addition of a small amount of salt to guard against any nitrite toxicity - “with 1mg/l nitrite and 10mg/l salt you reduce nitrite take up by 90%, so in 10,000 litres reading 1mg/l nitrite only 100 grams of salt is required to reduce the effects by up to 90%.” Your combined pond volume is 621 gallons/2823 litres, so, if my maths are correct, adding 30 grams of salt should do the trick. You need to use PDV salt, not just any old salt.

    Your second pond is not large enough to use as a quarantine pond (it’s also not deep enough to use as a pond for any of your fish) - I’m not sure how many fish you have in there, but if it’s only the 5 you referred to in your original post you will very quickly run into problems trying to maintain water quality. I would move the fish back to the main pond and treat both systems.

    Sorry the second pond was used to ‘dip’ the koi in a salt bath they’re all back in the main pond now with a water change and I’ll be doing regular water changes for the foreseeable future

    I only have four 10-15” koi the rest are smaller

    The pond has been fine for two years and I know it’s not over crowded I’m not a 100% nooby

    Was after some advise on the disease that has appeared this month

    The top pond is also just as a house really for the lilies, the small fish are just there to stir it up and help with water movements

    I know they can’t stay in there long and once too big will be moved

    Video I’ve just uploaded
    Concerned about the crowding issue but I don’t think it is

    Please view the videos and comment

    There are a total of three filters and two uv’s

    I’m not disagreeing, I’m concerned as I didn’t think it was anywhere near overcrowded hence the videos to help to see if this is the issue

    Koi look healthy enough to me but the pond looks more than 7ft x 3.5ft or is it deceiving.

    Must be deceiving, the sizes used to determine the water volume are obviously the internal sizes so overall it’s bigger than that, maybe 8x4 external

    Maybe this image helps Help please

    Sorry to go on about filters mate but when you said gravity filter do you mean gravity return ?

    Help please

    They’re above water level and fed from a pump at the furthest point in the pond and another pump goes from the bottom pond to the top pond filter and the returns down a pipe to the main pond via the top pond

    I'm inclined to agree with the answers already stated in that the problem here is almost certainly water quality.

    Once various bacterial issues start to unfold it can be very difficult to reverse them simply because the solution isn't easily available, that being better water quality that can only be obtained through larger volume or constant water exchange via a trickle in/out system through a dechlorinator.

    Using various treatments even if the correct ones for the symptoms isn't the answer because water quality has to be perfect first, and by trickling you are just going to dilute any treatments making them ineffective.

    I just reduced from 12 koi to 10 koi in my 2600 gallon pond because I felt there were too many for the volume requiring too much work to maintain water quality.... And I currently change 1500 litres per week.

    Rs do you have a link to the thread you did with the survey of peoples ponds think that could be a good read for the op . There are ponds that by numbers are over stocked but have filter systems to help cope

    Don't know how to get it on Tapatalk but will do when next home and on desktop.

    From memory the average koi per volume across this forum was something like 1 koi per 200 gallons but when adding all the non-koi into the equation it was 1 fish per 700 odd litres which I think it's about 1 fish per 150 gallons.

    Surely it depends on the size of fish tho aswell more than qty, oxygen and fish waste being important factors to the fishes happiness and health?

    Help please

    Based on 1 fish per 150 gallons I would have 3/4 fish
    And 2 fish for the recommended 250 gallons

    Would be bland and boring and not enjoyable to own, enjoy the hobby surely
