    Air pump

    Hi
    Im in need of some help with air pumps.
    Im currently growing some goldfish in a IBC just go test the waters and to grow some bacteria in the pond, until I go a step further and purchase me some koi , now iv got me a IBC filled to around 900L with a 200L air pump and a broken vase for shade/place to hide, Mum got me a few lilys etc around a 8 overall for extra shade /food source,But anyway let's talk air pumps
    I know im gonna need more oxygen in the water when I have more fish and plants, question is which size pump will I need in LPM or LPH, iv read up and they say in filters you want the water to cycle a minimum of 150% an hour aiming for 200% an hour.
    What's the working out method for air pumps and water volume ?
    I only bought a 200LPH air pump because it was solar... what a mistake in England 🤣
    So I reckon it's now pumping about 10LPH Air pump
    Here's my fish before I added the vase and lilys
    I now have 6 and the bottom is more of a green colour, Covered in fish poo Air pump

    Your air pump seems too small. I think it’s designed more for shallow water features rather than a pond. You are probably best getting a mains operated one. There are many cheapish ones to be found on fleabay amazon and fish street.

    Since you don’t have a bottom drain, it’s important you get good circulation throughout the whole pond, especially in the bottom corners where poop can accumulate. I would look to get air stones into those areas if possible. As such you may find it easier if you get an air pump with multiple outlets.
    If the air isn’t enough to ensure sufficient agitation in the bottom you could consider an internal flow pump also.

    The pump in the lower picture looks like an aquarium sump pump. What sort of filter are you using with this?

    Your IBC also looks to be in direct sunlight, which promotes algae growth. That may explain why the bottom is going green.

    The inside of the IBC will go green with algae no matter what, just like a pond.
    You dont mention any filter on the IBC. Have you actually got one?

    Any useful air pump will be rated in lpm not lph.
    What size you get depends entirely what youre going to use it for- tank / pond / moving bed filter or all of the above. You could buy a 35 lpm with a manifold and go from there- you would need to vent off a liitle bit of air if its only on a tiny IBC as you dont wamt a jacuzzi in there.

    Your right my air pumps way to small what would be an ideal sized pump?
    Iv moved my tank recently out of the constant sunshine but the green thing was a joke 🤣
    Im thinking of an allpondsolutions 1400LPH mains powered one ?
    Anybody had one ? Would they recommend another ?
    Iv got no filter atm im just gonna get the water circulating,until I make or buy ine
    Its a full sized IBC 1000L
    The aim is to have clear water thats crystal clear and fish safe

    The flow will depend on what you are aiming to do with the air. If it’s just gaseous exchange - ie adding a little bit of oxygen - then any pump will do. The higher the flow rate the more agitation you’ll get in the water, hence Feline’s comment about a jacuzzi.

    For crystal clear water you are going to need a filter. Probably more than you need an air pump to be honest.

    It looks to me that you are doing everything back to front. A pump, a filter and a UVC should be the first things to get as the filter needs time to mature. Unless the air pump is required to clean your filter by agitating the media it's no where near as important as the the filter system itself.

    To be honest my family have never kept fish the fish before were just fair ones that grew massive on the off chance.
    But today I tried everywhere for some 20mm pipe work thats flexible and came home with a mars bar and a plan to make a filter box and everything until i receive my eBay order

    Tested the water PH its around 7.5
    Now im just waiting on my UV clarifier
    I really should listened to you guys in the first place, the water went green much quicker than expected, but then I should of considered the depth and with the sunlight as you guys kept telling me.
    So lesson learnt.

    Its all a big learning curve for us all, just keep asking questions and the answers you will get will be based on other people making the same mistakes in the past and learning from them, this is my 4th pond and I'm trying to avoid the mistakes by asking all kinds of stupid questions

    You need to get a filter as soon as possible.
    the UV will only kill algae cells but the dead algae cells will only become food for nasties in your water until you can remove them.

    While led you are waiting for a filter remember to perform frequent water change to help lower the build up of ammonia and nitrates.

    I think he likes doing everything back to front or buying the cheapest parts first and the realising it won't work without the first and most important part - the pump, but then goes and buys something else that won't work on it's own.

    It's like building a house and starting with the roof

    Do yourself a favour, buy a pump and filter ASAP.

    You started this thread nearly 3 weeks ago now and your previous thread about making a pond out of an IBC nearly 8 weeks ago and you still haven't got a pump and filter yet!!!!!!!!!!!!!

    The sooner you realise that this can not be done on the cheap the sooner you will stop wasting your time and money and people on here's time.

    Also you don't need to keep writing - early learning stages take it easy now please on nearly every one of your posts.

    Well if you've got a pump and filter get it fitted ASAP as it will take time to mature the media and the time you've wasted you could have had it up and running and well on the way to maturing by now.

    Hi what filter have you got running? If reasonable it should clear the dead algae swiftly.
