Thank you for the interest.
I was just there yesterday but did not get any photos. I will get some next week to update.
Pond is doing great. Fish and plants are very healthy. Now that the weather has warmed up the Ultima filters are feeling an increase in bio load. They have to be flushed every week. After one week, the flow is decreased by 50%. This has caused a problem with water lost at the foot of the waterfall. The water returning to the pond at a reduced rate would stick to the wall and spill onto the coping. The pump has been turning back up to 3000rpm to see if the area will dry up. RPM may have to be adjust throughout the year to accommodate the seasonal load on the filter/flow rate. There is a noticeable in energy savings operating at a lower rpm.
Plants in the pond are blooming. Lots of iris, watercress, hawthorn, elephant ear and lilies.
