Summer vacation now so the progress should pick up a bit. Digging is never ending. It rained every day at first, then dried to cement the last few weeks. Finally got some rain last night to soften it up, and I got the bottom carved out a little better and around the bridge pier filled in and rounded out. The bottom is now becoming a bowl and is 6' deep and will have a 4" bottom drain.
The liner came in yesterday, 20x35 45milEPDM and is a nice 215lbs. The skimmer, BD, and case of brushes accidentally went to the wrong address so they are being sent out again and should arrive in a few days. I am heading out camping for the next few days and then will hopefully will get the bottom drain and plumbing to the filters done next week, along with digging the filter pit.
For filters the latest plan is: The bottom drain is running gravity feed to a 60gal vortex chamber for mechanical separation, and then to 90 gallon trash can filter full of banding for bio. For the top I am running a 4" remote skimmer to a 50gal square chamber (Walmart truck toolbox) full of black night brushes for mechanical, and then to either one or two barrels of banding or fishing line for bio. All of the chambers are going under the deck at the far end away from the pond where the old pile of decking is in the picture. The decking there will be hinged to access the filters. Each chamber is going to be connected with 4" pipe using uniseals and have a bottom drain for easy cleaning. I have a 2900gph pump for each line and the water will be pumped to the other end of the pond where each line will go through a 50gallon trickle tower and back into the pond.
In the last picture I have a rough outline of where the deck will be. The area along the fence where the scrap is will have the access to the filters. The deck up by the house with the lumber on it will have the Trickle towers inside of a bar facing the pond. I am also adding a door to the house to go directly from the bedroom out onto the deck.
keep up the updates
