    Yes understand that it won't be up to full speed yet , media wise it came with the 50litres supplied but due to a logistical error i ended up with a extra unopened bag of k1 as well ,I don't know how much is in a bag but its all in there ..

    Up the media lol. My nexus 320 I have 300lts of media. So I am assuming nexus 220 will hold 200lts of media.

    In the manual - "In optimum conditions 250g per day of average protein content food will be broken down by 50 litres of K1 Media."

    However, take that with a pinch of salt as EA's claims can be a little stretched compared to the real worldand there's no definition of optimum.

    I have 100L of K1 in my 220, although 25L is new this year so probably not effective atm. I'm in the south east and it has been very mild / hot here recently so my temp is up to 18C with a little help from the ASHP. Anyway the fish are gagging for it and I have been caning the food for the past few days - up to 300g per day (pond is 10000L with approx 10 fish average 50cm length). I've been keeping an eye on the parameters and the nexus seems to have got up to speed quickly this year - ammonia reading is zero yesterday and today.

    I started feeding once a day just over 2 weeks ago and upped to twice a day a week later but only feeding a very small amount. Will go to 3 feeds a day early next week and then will start to make each feed slightly bigger each week.

    When it comes to feeding i think the general rule of thumb is start slowly and stop quickly.

    Also it can depend on what sort of food.

    Whilst ‘feed the filter’ mentality is a good one, food quality and digestion for the koi is equally important to consider.

    The koi behaviour and water readings will help, however every time the koi see their they will ‘think food’ (as this is what we mostly do when we see them) and their behaviour can change which can lead keepers to think the koi are permanently hungry.

    Observing the koi without them knowing the keeper is there can tell a different story at times.

    Cheers

    Spot on Gaz

    BTW I've already trade marked that term "rule of thumb" and the going rate is £10 for each time it's used lol

    Well I have to make money some how during the current lock down lol

    The behaviour of the fish can tell you quite a lot, as last year just by chance I was reading a thread on here and someone mentioned that they had a raised nitrite level which was causing their Koi to take food but spit it straight out again. A few days after reading that my Koi started doing the same thing and after testing the water I found not only was my nitrite slightly raised by the oxygen levels were very low so reading that thread probably saved my Koi

    So true, when I have the air on the bottom drain they are mostly mid water and lower in the pond, the second I turn it off now they are popping to the surface like corks because I turn it off to feed them then they linger around after the feed hoping for seconds and thirds. Its also amazing how much a pinch of 3mm pellet looks like on the pond when in reality its not even half a mouthful for a 30cm fish if it was all grouped together on the top. I am feeding twice a day now the temps up a bit, some sinking Ogata koi farm food in the morning before I go to work, then floating coppins when I get home with the air off so I can see them all.

    I've been using the Orchard farm fisheries premium food for a few years now and they seem to like it as it doesn't last long when it goes into the pond.

    As I was moving stuff around in the pond so I could see about fitting an in wall skimmer, when I fed them last night they were all a bit cautious and then they all kicked off trying to get to the food but stay under cover at the same time and 2 of the larger ghost Koi jumped out of the water and high jumped over the bar of the auto top up system. They settled down to a slightly more normal feeding session after that fortunately lol
