Owner is really having fun. Has got many eating from her hand!
Took a month or so longer than I thought to clear up but I just recovered a 2″ piece of 1″PVC pipe from the deep end.
I “love” trying to take pictures that really show anything. I know it just looks light green but that little piece of PVC is _10_ft down with no toxic algaecides. There are a huge number of ponds in Los Angeles less than 2ft deep that are not clear. Look at all the (anti)algae stuff for sale on any pond store site. :-)
Wait till they get big! She will have 2 to 3 ft koi!
Best to all.
