Hi
1000 gallon pond, steep sides, no plants, 5 Koi, all test readings low except for PH (8.5). The pond is about 15 years old. In the last five years I have failed to maintain a clear, algae-free pond for longer than a couple of weeks. Oasis green2clean 24000 combined filter and UV (25watt) with an Oase Aquamax 8000 (litres per hour). I have tried a whole range of products and processes to try to clear the green but nothing lasts more than a week or so. I have completely replaced all the filter pads (I had an infestation of worms in the old set and wondered. Whether this was causing part of the problem). The garden is south facing and the pond gets direct sun for most of the day.
I have two questions...
Short term - can anyone suggest any products or processes that might clear my pond?
Long term - Next year I am looking to redesign the water feature and could change the filtration system for a new one at the same time. Recommendations, please, for what I should consider purchasing? I live in South Wales, UK.
Many thanks
Chris
