    Not much to show that adds to yesterday's progress shots. The "legs" for the Nexus units are about done, and there is a lot less dirt piled around the pond as the outer trench is getting back-filled.

    Using concrete block, when a wall curves there is a basketweave effect created. The sharper the curve, the worse the effect. The photo shows the tightest curve in the pond. This will guarantee that fish will get scraped and lots of little ledges on which waste will settle. I believe the guys will be addressing that issue today, among many other things.

    Mike

    Thanks for posting all of these pictures. I'm in the process of building my own pond right now. The hole is dugged working on final shaping before concrete. All of these pictures and comments are extremely helpful. I wish pond progress move as quickly as yours.

    what is the dimension of the pond and how many gallons?

    Redhot: I've had a wide range of estimates on gallonage from 9500 gals to 12,000 gals. The egg shape is tough to estimate. John McDonald, Keirin's filtration specialist, eyeballs it at 12,000 gal. I hope he's right. But if it is more than that I've got problems. I'd like to have the pond volume turn over every 45 minutes. Will be moving 16,000 gal per hour (conservative estimate) through one filter or another.

    I've been having to work today, but here are some status shots.

    Concrete base to the pond has been poured and given an initial finish. As it sets up the surface will be given a smooth finish. Meanwhile, the piers on which the Nexus units will sit have been finished, and given a smooth outer finish... nice to avoid scrapes when reaching under them.

    And, here you can see irrigation lines that had to be routed around the filter pit. One of the lines carries water at all times (busted during excavation, of course; but fixed ... amazing more irrigation lines have not been destroyed, but not done yet!). It is the one with stub heading toward the filter pit wall. One of our ad lib changes is to add a water line to the pit. Since the line runs so close, it was an easy decision to make. Maybe in the future there could be an auto-fill device added, as well as a spigot? ... LOL. It is going to get cramped in there!

    There will be 4 nearly independent filtration systems on the pond. (Had to make a compromise due to space constraints & will point that out in due time.) The two bottom drains are served by the two Nexus units. Each of them will handle about 3,000 gallons per hour. One skimmer feeds the Bakki Shower at approx. 5,000 gallons per hour. The second skimmer will feed a bead filter, also about 5,000 gallons per hour. The bead filter is one I already have (now on the holding tank). It will be in the filter pit with the Nexus units .... really getting cramped. Fortunately, John is space efficient in the plumbing lay-out.

    My work day is done, and it is nice to see that much of the back filling around the pond is done. And, the floor of the pond is nicely smoothed.

    Mike no doubt you put some thought into this. nice to see it coming along smooth. Speaking of smooth have you figured out the sharp corners of cinder blocks? Just curious as to what type of mesh that Poly could adhere to to roudn out corners or something to make that corner smooth..

    But, around the corner it is mass destruction time, again. The trench for the drain lines to connect between pond and filter pit are being dug. Big equipment eases the task somewhat, but it takes hand digging when more irrigation lines are discovered! Fortunately, John is a whiz at repairing them (after the dig is done, of course). If you are wondering why so much dirt is being removed, you'll just have to come back another time. We still have something to install (in recognition of all the leaves, etc. that will get blown into the pond).
