    In pond skimmers

    I already have a 10 x 4m pond and have been using a floating skimmer when needed but obviously these are very small and block very easily. It is too late to incorporate an external skimmer. I am looking at these skimmers and I wonder if there is any reason why they cannot be used if anchored at the edge of the pond but in the pond. I am sure I can easily disguise it.

    Hi Syd and welcome to the forum .

    Usually , to fit one of these requires chopping part of your pond wall away , and the skimmer sits in the actual pond wall , with the suction part in the pond , and the pipework going outside and into your pump . Not sure if there`s a way of retro-fitting one without some sort of de-construction to your pond wall .

    Maybe someone else will suggest something .

    Good luck .

    That's what I cannot do now due to rockwork and landscaping. Unless I'm missing something, the only reason I can see these skimmers are external are for neatness. Provided I support the unit I reckon it should still work perfectly well in the pond. Not ideal, but neither is the floating skimmer.

    Just been fitting a skimmer back into my pond, I have had a revamp and decided to move the skimmer to the other end.
    I used a floating skimmer last summer but seemed to be forever emptying it.
    If you put a skimmer in the pond you will still need to get a pipe out below the water so probably easier just to cut the wall and put the skimmer in then redo your stone work.
    Just finished putting the stone capping back on tonight just need to seal it the end of the week.
    I had also thought I could use a return to take the water out but decided again it's more bits and pieces in the pond that are probably better out.

    Thanks for the reply Sim. I'm confused. I don't understand "you will still need to get a pipe out below the water". As I see it, I put the skimmer in the pond at the right level for the water to flow in, and then connect a submersible pump to the bottom pipe and just discharge the pump to the pond. I have attached a Tetra diagram. Could this not be done with a large skimmer?

    Yes oase do a couple that do this but the baskets that collect the debris are small so you have to keep emptying them.
    They do one that is weighted to the bottom and as you say connect a pump that sits in the pond.
    It adjusts to small water height variations.

    you could take basket out and just pump through a small filter,,,andi

    The small baskets on those units is the reason I wondered about adapting the larger external skimmers. I have a small Oasis floating skimmer and it is useless. Well before the small basket is full, the flow is blocked by debris which empties the chamber which increases the buoyancy and the skimmer floats higher in the water with the inlet up in the air. This can happen in a few minutes.

    I have looked at the Aquosis SK1 that Andikoi suggested (thanks Andi) but due to the type of basket I wonder if that would also block before it is full. It may work ok with the deeper steel basket but that's getting quite expensive for what it is. £190 for the skimmer and steel basket and then there is a dry pump to buy. However if it works......

    You could do it this way - its just a bit messy .Ideally , you want all the pipework and pump outside your pond , not in it . It`s just cleaner and simpler this way .

    The system in the diagram says your pump discharges into a filter , by the way , not directly back into the pond . Its better if the water you remove is filtered , otherwise you`ll just be sending bits of crap that your skimmer basket lets through , back into your pond .

    Personally , I think , if your going to the trouble and expense of replacing your skimmer with a new system , I`d try and come up with a way of fitting which ever system you use , as it should be fitted .

    The one Andi suggested looks like a good compromise and requires less work to fit . Its costing you a bit more , but saving time .

    I appreciate the external positioning would be best but I just can't face ripping up the stone edging and incurring the wrath of my wife when her plants get dug up. I think the Aquosis could be the best compromise. Tetra do an interesting In-Pond skimmer but it does not appear to be in the UK. I have contacted them. Thanks everyone for your assistance and suggestions.

    i take it your on about this one,still needs cleaning though as has mats in to collect debris,and needs supporting on something unless you can make a bracket to hang it over the edge,,,andi https://www.ebay.co.uk/itm/123450658487

    That's the one. It looks a reasonable size for collection. I have a couple of suitable positions for it in the pond. I'm not averse to cleaning it out, just not every day like the small ones require. Still waiting to hear back from Tetra on availability.

    i know this may sound daft but have you thought of just putting a submersible pump in a corner to skim off the top inch of water,if you put a 90 bend on the inlet and sat it so its an inch below surface you could then just pump water to a small box filter and gravity return,,,,just an idea,,,andi

    I did think of something similar but there's a couple of problems with that. The water level varies and some of the debris will be leaves. It needs to be either a floating overflow like the Aquosis or a large throat like most of the normal skimmers.

    i think for you maybe the aquosis 40 would be good,you can also buy extra pieces of pipe i think as standard its max is 88cm,,andi https://www.cotswoldkoi.co.uk/produc...m-40-standing/

    I think you're right about the Aquosis. Shame it's so expensive. I shall wait on Tetra to see if theirs is available which is considerably cheaper if I can get it in the UK. Thanks for your thoughts.
