    Your views on pond lights

    Good afternoon all, i am only a few weeks away from the team at m2koi coming round to start my first ever koi pond, i will be having an above ground pond 330cm x 240cm x 5ft deep (1ft in the ground), it will be a BD gravity system via an Evolve 4000 drum and bio combi unit, UV and skimmer, there will be a window 1.8m x 1m, i will at the time take some pics of the build as it unfolds....... a few Saturdays ago i had the pleasure in meeting "Craig" from this site who lives local to me and had a very informative afternoon, one of the topics discussed was lighting, from Craig's experience he now has his lights out of the pond above and facing down into the water column as he was regularly having to clean the light lens whilst in the water due to algae build etc, i wondered what you guys do regarding lighting as we will spend a lot of time outside especially in the evening looking into the viewing window so wanted to see the fish in the dark.....do you have your lights submerged or above pointing down ? is there a max watt that should be used to avoid fish eye damage ? any colours to avoid? any information would be appreciated....

    all the best Steve.

    Iím hopefully going to put LED strip lighting around the under side of the coping stones which are rated to IP65. I had lights submerged on my old pond with different colours and as mentioned they all eventually went green. My strip lights will be warm white as I think coloured lights make it look more like a disco than a pond and donít show up the colours of the koi well but each to their own

    I'm going to put lights back on my pond when the new electrics are done.
    I will put them on the under side of the pergola pointing down into the pond. I also like the water effect of the light bouncing off the water onto the surrounding area (a shimmer effect) which you get with this it's quite relaxing.

    Just be aware that any underwater lights will cover in algae just as the
    one sides do so will need regular cleaning. Make sure you can reach them!

    Hi I have an 10w led floodlight shining onto my window at an angle so no reflective glare. Had to play around with the positioning to get the angle right though. We can watch them all year round at the window from the conservatory.

    I have a set of the Blagden submersible LED lights. I took them out a couple of days ago. In my experience:

    The bottom drain drags the lights around even if you weight them by fixing to lumps of stone.
    The wires are a nuisance if you vacuum the bottom of the pond.
    They green over in a couple of weeks.
    I don't find them all that effective. I am going to re-use them as garden lights.
