    Water blade advice.

    Hi all, don't post very often, but have been an avid reader for a few years. Looking for some advice from other folks who may have installed a water blade, as to the best height to install from the finished water level.
    My concern is that if to high, the water curtain may start to taper in before it hits the water rather than staying as a vertical curtain. Have any other members found this to be the case?.
    The blade I am intending to fit is 600mm wide, fed from a 20,000 lph pump which is also supplying return pipes, all ball valved to control flow.
    I am hoping to install it about 600mm above the water level, do you think this may cause a problem?
    Any advice appreciated, many thanks.

    I am also looking to install a blade, not sure which you have chosen but I downloaded the instructions for one and it had this handy guide:

    remember the higher you put it the louder it will be plus more chance for wind to blow water about as it falls,id say 6-8" which is what my shower is at and also on a 20k pump but only at 70% due to drum flow restrictions,,,,andi

    My hight from top pond to lower is 6 inches. Never touched back wall in lower pond. No matter what the wind speed.
    Also as andi says. Not to noisy

    I've got two 90cm waterblades on different ponds, the first one was installed about 70cm above the water and only protrudes about 5cm from the wall, therefore I can only switch it on when there is a gentle breeze otherwise it gets blown about quite a bit, it probably wouldn't be a major issue if it came out from the wall another 10cm. I'm pushing around 10klph over it and I don't think its that noisy.

    The second waterblade isn't up and running yet as I haven't finished the pond but it's only 30cm from the water level and protrudes around 20cm so lesson learnt from the first one (I hope), it's also a curved waterblade whereas the first is straight.

    Many thanks to all who have replied, your advice has given me quite a few things to consider. The blade I am using will project 10cm from the wall which is being rendered with k render. If I find the render starts to stain, I may have a piece of stainless made to act as a splash back. Will let you know once up and running.
