Enviroswim cell maintenance. I have had to remove the oxidising plates from the cell 4 times over the past 3 swimming seasons. I have been informed from the manufacturer that this is a result of my pool chemistry being out of balance, however I have been fairly careful with my water chemistry and see it more a problem of the product. It doesn't matter that much but I feel that it could be included in the maintenance manual as I have read of several other Enviroswim owners with a similar problem. It is fairly simple to dip the plates in a weak hydrocloric acid solution (about 1 to 10)which cleans them in about half an hour. Note I use goggles when I handle acid. The plates are shown soaking in the background (blue icecream container). I cut a plastic bottle of a similar diameter to the plates down to the correct size so that the entire active surface could be cleaned while keeping the lid out of the solution as I didn't want to damage the electric terminals. I sat the soaking container in an icecream container to act as a catchment tray for the excess acid as it foams and bubbles over the edges of the soaking container. Other things to note in this picture are replacement rubber sealing rings for the canister. I used these as the originals had degraded and the ionising chamber was leaking no matter how hard I screwed it on. As my chamber is below pool level I have more constant pressure on the canister. Note the small spiky looking object just to the right of the enviroswim electrodes. This is one the original electrodes after I have unscrewed it from the chamber. After 3 years there was not much left of the electrodes but the system still continued to function even with the electrodes worn down to tiny nubs. I removed them at this point as the maintenance manual explains they must be removed before they fall off.

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.
