Hi,
We have a large pond (about 5000 gallons) in our back-garden. The pond is exposed to direct sunlight (when its out!) for about 8 hours a day. We used to have a serious green water problem and had to start over and install a filter. This solved the problem of the water looking like a pea soup but this year we have a had an complete infestation of a different type of algae. We at first thought it was the all to common blanket weed so treated that with a blanket weed treatment which had worked in previous year but that failed to do anything and stuff was complacently saturating the pond, covering plants and oxygenates in greed clumps and longs strands and clinging to the sides of the liner. It will also float to the surface and float around in clumps.We then tried to vac the whole pond and do a partial water change to try and clear it out. We took away as much as we could so we could see the liner and plants again but literally the stuff was back the next morning. I have attach a few picture of what it looks like now (the day after giving the pond a vac). I would very much appreciate any advice on what could be the possible cause of this, what type of algae it looks like it could be, and what a possible solution is. If its anything to go by we have never had very many leaves from our waterlilies despite and feeding them and re-potting them and trying placing them at different depths in the pond. We also have tried different species of lilies but all have failed to flourish. Any help with either of those two problems would be much appreciated!
