Enviroswim electrode replacement. The ioniser means the pool is as close to fresh-water as any system. The Manufacturer stated the electrodes should last about 18 months. I ran my pool filter with the environswim active for about 6 months a year. I was running it for about 2 hours a day for a couple of the cooler months, abour 6 hours a day for the warm months and around 8 to 10 hours a day in the very hot weather. This was the minimum required to stop the pool going cloudy. All taken into account the 18 months time-frame seems like a reasonably accurate figure. I am however running my filter with the Enviroswim on for a little longer than I had expected from the product literature. This shot is of the replacement electrodes just before I screw them back into the ionising chamber. The replacement electrodes come fixed to stainless steel end bolts which were slightly shorter than the originals and the replacements came with two seating washers unlike the originals which only had one. It was a tight fit to include ever nut and washer (and there are plenty). I noticed the original nuts required a no 10 metric spanner to undo them and the replacements fitted a 7/16th spanner nicely. This slightly larger bolt diameter means that unlike the originals which just slid through the housing cap the replacements needed to be physically screws in and tapped a thread into the plastic as they did. This means a tighter fit and presumably is more watertight, but I will be curious to see how easy it is to remove in 3 years time as even the old one required a bit of force to extract it from the lid.

This Architect Designed Pool in Outer Metropolitan Adelaide was an Owner Builder Project

I drew the plans and provided much of the labor myself, providing a cost saving of around 50%
This Swimming Pool is situated on a hill with a 1 in 3 fall. The site is tiered and over 50 stairs have to be negotiated from the street. Due to the difficulty of site access all materials had to be carried in by hand. The site was also excavated by hand. Provision for a fully enclosed glazed structure around the pool complicated the build by imposing additional structural requirements.
I designed a concrete shell as this could be used as footings for the room over. The structural Engineer advised to found the pool on natural ground.  This advice meant that some structural savings could be made. Instead of having to use piers, a series of strip footings could be used to key the pool into the hillside.  By following this concept the design of the pool became what is known in the industry as a "split level pool." This means that the depth increases from side to side rather than end to end. This has the advantage of giving a fairly continuous depth swimming lane for the entire length of the pool.
There were serious space constraints due to the existing house and garden layout, and an existing sewer easement at the rear of the property that had to be avoided. The room over is still under construction. If you live in Adelaide and are thinking of putting in a pool or pool enclosure - email  I will make sure your pool suits your site and integrates into your garden. An architect designed pool is the difference between a suit off the rack or one tailor made..... and the best bit is that if you have your own plans you can shop around for the best price.
