Some improvement, but not there yet

"Pumped out my pond filter and then added Algae Klear Xtra and also Pond Klear weekly for the last 5 weeks. There is some improvement to the algae but it has not worked as well as I hoped it might. The stones are still covered, which is a bit disappointing, but the plants are not as covered with green strands as they used to be, which is a good result. The water has been very clear throughout. Not quite sure what to do next. Might give it another 5 week dose, but it's now getting a bit costly. Envii have been very helpful throughout in giving advice but I'm beginning to think that algae are quite difficult to clear."
