Ok so I was terrible at taking pictures to show everyone what the bottom of the bog looked like, but it was as I expected. A solid foot of muck and my DIY bog plumbing was completely clogged. I removed all the rock and muck with a shop vac. I excavated the hole a bit bigger to comfortable fit the new snorkel and pitched the centipede trench back towards the snorkel. Placed all the aquablocks and filled back in the rock. I definitely have a lot of left over stone with the aquablocks in there, but that’s alright. I redid the plumbing and put in my breather pipe. The pond and bog is operational again. Just need the water to clear back up as I made a bit of a mess in the back. I’ll work on the boulder placement and edging tomorrow.
