Nell and I both had dentist appointments yesterday. Her’s in Las Vegas, mine in Mora. Both went well and we returned here early in the day. Nell has been planting in seed trays for the last week, in between unfathomable amounts of paperwork. I decided I’d put off the finishing touch on the pond interior long enough.
I realize these look like featureless gray, but that is sort of the point. The next step is sealant. The sealant is expensive and we’re trying to minimize the amount needed by smoothing the surface as much as possible beforehand. The same goes for the next layer which is an even more expensive product called Hetch Rubber Koi Pond Coat. This is also a paint on product. Before either of those products can be applied the cement needs to fully cure. Curing will take around two weeks from the application of this last coat of stucco.
Here are some pictures from this morning. Included in this section are the two more plumbing systems. Heavily researched, probably over-thunk, but set in stone nonetheless.
You may be curious what a SLO is. SLO – solids lifting overflow. I made this outflow many months ago. Later I learned that a 2″ SLO is ideal, I made it 1.5″, oh well, it is as they say,”set in stone” now.
The purpose of the SLO is to gently collect solids from the bottom of the fish tank. In our pond we went with the natural contour of the bedrock in which we carved the pond. This created a slope on all sides towards the deepest point in the pond, a trough, approximately three feet long. My plan is to place a perforated pipe lying horizontally in the trough. I’m speculating the solids will eventually sink to the trough, where a hopefully gravity will draw them up and out through that 1.5″ pipe and into a set of filters. I’m of course uncertain the lower SLO outlet will force enough off the bottom. I’m prepared to have a small auxiliary pump pull the solids through the filters before they reach said pump. This is why I want filter barrels that have lids which can be sealed, to create a vacuum.
I’ll use this time, while waiting for the cement to cure to build the first media grow beds.
