    New pond problems In Gloucester

    hi,
    About three months ago I took delivery of a pond from ez ponds and I am having massive water problems both in colour and the levels of ammonia and nitrate etc are alarming. I am using a used nexus 300 with a Bermuda 10000ltr per hour pump with an evo 30 uv. The pond and the nexus equates to 9000ltr of water.
    is there anyone near me that can help?

    How many fish do you have in there?

    Do you mean nitrite or nitrate?

    When I started my grow on tank last year I had a constant water feed to keep the ammonia and nitrite down until the bacteria established in the filter, that was 8 small fish and a nexus 200 and it took months to be honest

    The nitrate and nitrite are both bad.

    I was thinking to buy a more powerful pump and an evo uv55 to try and help.

    Someone had suggested that I add a bacci shower?

    It sounds as though the biological side of your filter isn't established yet.

    Have you added any new fish recently?

    3 new ones which someone was holding for me but he was not able to hang on any longer

    Don't be to concerned about the clarity for now, a new pond will go through lots of changes.
    Water changes to help dilute.
    Slow the feeding down.
    Use zeolite etc to catch the ammonia

    The shower would also help

    the only thing I would add is feed very sparingly until the filters mature.

    Hi Andre.

    How have you calculated that the pond and Nexus equates to 9,000 litres? The EZ 1200i (internal dimensions) would give you 6,054 litres, the next model up, the EZ 2000 would give you 9,272 litres - I don’t use a Nexus so don’t know how much additional water volume this would give you. It’s important to know exact volume for any treatments.

    15 fish as they grow will be quite a load on 9,000 litres, if that’s what you have, more so if you don’t.

    As others have said you seem to be suffering from new pond syndrome, but it would be helpful if you could post your water parameters i.e. pH, KH, ammonia, and nitrite, plus your readings from the tap. Also, can you describe your maintenance, water changes, what you do to dechlorinate plus any treatments added to protect the fish from swinging ammonia/nitrite.

    There are plenty of very knowledgeable people here who can help you through the problems you’re experiencing but, should you require ‘outside’ assistance as well, I can recommend someone close to you who is based in Cheltenham - unlike here, their assistance is not free!

    I wouldn’t be concerned all perfectly normal. NPS. Your pump UV and pond size are similar to mine. 5 weeks in all I have is ammonia, quite looking forward to some Nitrite!

    Another question but did you treat the k1 with potassium permanganate before you started up?

    Nitrite is worse than Nitrate and can be stubborn to move on.

    Heat will help pass the Nitrite and mature the filter, as will EA pure gel.

    Salt will help protect the Koi from brown blood disease whilst the Nitrite is high.

    Be sparing with the food (not high protein for now).

    Cheers

    Sure, elevated levels of ammonia, then nitrite, then nitrate are to be expected as the bio filtration starts out and then matures - all normal. But I thought Andre was asking what to do for his fish when “alarming” - toxic - levels of ammonia and/or nitrite occur during this process.

    Cross posted - I was replying to Spongebob.

    Think we need the water readings to understand what alarming means, then we can work on emergency measures if required or longer term fixes if not?

    Hi All!!

    I cant thank you all enough for your help!!! Never joined any type of forum in my life and I really appreciate all your thoughts.

    I will get the levels posted tomorrow. I use a dechlorinater which is only put on a trickle to allow the unit to work.

    Thank you all

    Much of the signs are not visible as damage is internal, however some signs are:

    High ammonia can lead to sunken eyes
    High Nitrite can lead to brown blood disease
    Koi can sulk, flick, flash, jump and/or clamp
    Gasping as the surface can also be a sign something is wrong
    Lethargy
    Not eating food
    Fatality

    Cheers

    when you go through New pond syndrome. its about keeping your water tests as near to zero as you can. it is easier to get under control then. when you have done your tests put them up on here pond and tap tests.
    reason for tap tests is because you could be adding ammonia as an example when you do water changes. so we need ammonia nitrite ph nitrate KH. there the main ones. also do you have a dechlorinated liquid to add for water changes.

    when one of the tests goes from zero to showing a up reading, first thing to do is stop feeding or cut down .if high stop altogether. then do a water change of say 10% to start diluting the ammonia and nitrite down, once its down
    to zero add a little feed. then once you get another up on your ammonia and nitrite stop again. and so on. its all about the filter and pond bio catching up.
    put a load of ea filter start blue gel on all your filter media lol. gaz of aurora koi sells it,
    fred
