Hi everyone! My husband and I just purchased a home in clear lake, Texas. And it came with a gorgeous pond! We are complete newbies, and are trying to learn as much as we can to keep this thing looking pretty! We moved in and our pump was dead, so we replaced it to get the waterfall going again. The pump was off for two days. We will be buying test strips soon to check the ph, and nitrates. We have 5 koi, and a ton of tiny fish (not sure what they are. Maybe tadpoles?) and water lilies. We contacted a pond servicing company here locally, and he told us that we needed the entire thing drained, and cleaned. Also that the lillies have taken over the pond. (He made this deduction from the photos posted.) any advice for a newbie?
