can anybody tell me if using a filter with a uv lamp will solve my problem of green water in the summer or should i go with using more pond plants
Yes it will netty if you calculate the right size filter for your pond,usually it's mainly koi keepers that use these devices, you can have a nice clear pond with the right balance of planting,if you cut the amount of sunlight falling into the pond by introducing surface growing plants this will help the situation
Hi Netty, In the spring there is always a bit of a problem because the water plants haven't got going which give you the shade from the sun which is causing the problem, all those nitrites are having a ball, but you could try your own weapons of defence with plants that devour these, and starve the algae, such as watercress, or reeds, or even busy lizzies put afloat in their water baskets
Hi Netty The answer is yes I have two filters in my pond and I run them Winter and Summer.I have a bridge over the pond which gives some shade,and two Lillie's which cover about a third of the surface and its always crystal clear.hope this has been of some help.
Something I have been thinking about too. My pond is only small and they say the smaller they are the worse the are with green Algae. I have plenty of shade but few plants, must look into both.
A filter of the correct size will solve your "problem" how ever you must also take into consideration the pump and its flow rate. Too fast the filter wont work, too slow the filter wont work. Koi keepers aim on average to turn the pond volume over once every two hours. You should be looking at about 4 hours. That is to say if your pond is 100 gallons you should have a pump that pumps 25 gallons / hour. Also the pump should be at the opposite end from the filter outlet, otherwise you will be sending the same water back through the filter
