One week into the DIY biofilter resulted in crystal clear water and a very nasty biofilter. I don't know how Skippy can advise not to clean the filter! I am glad I built in a bottom drain to backflush, there was so much debris and deitrus. If anyone is building a biofilter based off the Skippy design, I highly recommend you putting some sort of drain to help with the water changes, it is so easy now.
I also started to rock everything in and make it into more of a smaller waterfall with a bunch of rocks to trickle down to help with aeration. One thing that stinks is I ran out of rocks/cobble. I also laid down some weed barrier and spread out some meramec pebbles so I dont have all that growth from the existing creeping jenny(I think). I was so busy I forgot to take some pictures of the progress, but finally after relaing after a hard days work, I took some night time pictures of the waterfall.
And for those who ever wonder why you are so tired after working on your pond, I wore my heart rate monitor to see how much energy I expend moving all the rocks and boulders - 3803 calories burned in 5 hours of ponding. Gives us an excuse to monkey with our ponds, we can say its exercise!
