Wow, yeah, I would definitely NOT do what this company is advertising. That sounds to me like you'd have to re-cycle your whole setup again afterward! No thanks!
For the string algae, mine became really bad this summer when the weather warmed up and the pond started getting more sunlight. I use algaefix periodically. I also tossed in a bale of barley straw a couple of weeks ago. It doesn't get rid of it completely, but it seems to keep it under control to a certain extent.
I've not vacuumed (how DO you spell that word? LOL!) the pond before. I probably need to.
