    Sounds like a big hole Steve,would it be a good idea to slope the bottom to the drain like a saucer so all the muck can collect towards the drain.
    In my opinion 1.5 mtr depth would be the ideal and 12x10 mtr for the pond you may have problems if you ever have to catch them,maybe a small boat would help.

    And john it depends on the size of the fish.

    LOL The liner is 12x10 so at 1.5m deep it will be about 8x6m surface area.

    I am thinking your 3% salt is a typo and I hope you mean 0.3%. Koi do not do well in sea water ....

    If you heat to good growth temps of 24C then you should find you can mature your filter in a few weeks. Fortunately your fish load will grow as the filter does. It would have been ideal to try and fishless cycle the system prior to the fry arriving, but if you keep on top of testing and are prepared to do some serious water changing then you should be able to get them through it.

    Do you have any mature pond media you could 'borrow' for the new tank for now? It doesn't completely prevent NPS but really helps shorten it if you have.

    Hi Feline
    Yes a typo, it was 0.3 now 0.1 lol.
    My ammonia went up to 1 but has dropped to 0.6 and my Nitrogen has gone from 0 gradually up to 25 ish now.
    So Iím thinking the filter is working,
    Thing about moving water temp up to 24, which I would like to do is it makes the ammonia worse for the fish. I think thatís what I read the other day.
    I donít have any other tank of mature filter medium Iím afraid.
    Oh also I noticed my water hardness has changed over the last two days, itís been a constant 15 drops to turn to from dark pink to blue, two days ago it was 14 drops, and yesterday 13. Not tested today yet. So it looks like the water is getting softer.
    I think thatís a good thing?

    Well it looks like your little fishies are crapping like they've been out for a curry starting a new filter so it might be that you need more media in the filter or faster through put because the ammonia eating bacteria is usually the quickest to mature and they arnt coping.
    If you mean nitrates not nitrite , god I hope you do are rising you will need more frequent water changes. I know they are not dangerous but they create a bit of a, what I can only describe, as a bad smell in the water.

    Oh and if your hardness is changing I believe it may effect your Ph so keep an eye on that too.

    Well that's how I understand it, anyway

    John
