Sissy,
Stumps are great if you can move them without breaking the roots extending out from them. That place I posted pictures of earlier has an area full of cedar that have amazing roots and a lot are stumps sitting in the ground or trees that fell over. Some amazing ones, but too big to carry out and also on a city park area so can't take them out anyway. I'm surprised the lumber yard gave you permission, even though they said at your own risk. You think they would be worried that someone would get injured, get a lawyer (not saying you would, but they don't know that), and sue them for getting hurt. Or even worry about your health insurance company sueing if you get injured. But cool that they let you go in, I'm sure you find lots of cool abandoned objects in them. And when you like to do a lot of hobbies, free always helps and is a lot better! lol
Even though its 60 degrees out today and the next couple days, I decided to shut down and take out the filter since it will get down to the 50's for highs and in the low 30's at night by tuesday, and should stay there and keep going down for this time of year. Plus I wanted to rinse out the filter before I stored it for the winter. When I cleaned it out I found some interesting bugs in the sponge part of the filter. Has anyone seen these larvae before?
I also found this guy just hanging out in the pond, have seen these bugs in it before, does anyone know what kind they are?
And here are some pictures of my fish, they have settled down with the temps dropping and mostly just hang out around the bottom of the pond. I haven't fed them this summer and plan to start in spring. Its recommended to use different food for spring/fall right? For the summer I was planning on using the Wardley Pond Pellets, does anyone else use these? Mostly like them because the cost isn't too bad and they are available locally at Walmart so I don't have to have them shipped or spend more for the name brand Koi food pellets from Petco or Petsmart.
