You can also buy Ozium oxygen spray. I'll find out from my daughter where she gets it. I personally have not seen this product in a regular grocery or bix box store. I'm not advertising or spamming. I'll get back on this.

lbridges, my apologies for not addressing the point you raised, but I missed your post. You raise a good point. It wasn't my intention to imply this work was conclusive. Frankly I think it is far from perfect for a number of reasons and you have added another. Rather I posted it because it at least raises an interesting question, do we know if guidelines that are so widely accepted are correct? Even more important they suggest what sounds like a reasonable method for determining how long a filter needs to run (I think we already have an answer for the sanitizer). Test the return water. If it is as clean as the suction water, there is no reason to be running the filter. There might be a better or more complete method, but its a start. Pool owners spend a lot of time testing the water to make sure water parameters, including sanitization is where it should be and for good reason, the consequences of failing to do so are dramatic and potentially very costly. Yet we spend very little time thinking about filtering, or at least over filtering. Again with good reason, the consequences are less obvious and onerous (a high electric bill). But that doesn't mean its impossible, quite the reverse. Dismissing the study as imperfect misses the point. Calling a pool a luxury in order to justify poor design makes no sense. A more reasonable response should be to say, interesting data, we should try and learn more and see if it possible to rethink how we operate our pool equipment in a way that maintains water quality yet consumes less energy. It is a noble goal and one that appears likely to pay off. Two of the biggest advances towards this end would be ECM motor powered infinitely variable speed pumps, like the Intelliflo and venturi skimmers. Where previously pumps had to be sized for the maximum flow (like when the heater was going) flow rates can be set for whatever function is currently being called for. This is a massive change. As for venturi driven skimmers where previously it required pumping 40 gpm through the suction line, all the piping, filter, pump, heater with their respective losses (and energy consumption) to achieve 40 gpm through the basket, these skimmers require only 8 gpm to move the same 40 gpm of water. That is a big deal. Even without reduced turnover times just these two changes can make an enormous change in the energy use of a pool. The possibility of lower run times on top of these lower flow rates when running, merely add to the energy saving opportunity. This is not esoteric stuff. Pumps die and need to be swapped out and there have been numerous discussions on this forum asking what the expected energy savings are of replacing a single speed pump with an Intelliflo (or a two speed pump). The answer if you just swap out but program as before is not much. The real gain and its big, is to use the capability of your new pump to run at any speed to run at the right speed for each task and to only run as long as is necessary. Luckily this is easy to do. As best I can tell the resistance to do so is mostly due to a lack of understanding of how to calculate the proper flow and turnover rates. Not wanting to make a mistake that will come back to bite them and unwilling to admit they don't understand how to calculate the proper answer its easier to put out vague assertions about why its bad or will cause problems. I'm an engineer. I don't think its scary when you don't know something, its a challenge. Either you poke around until you find someone who does (hence my posts here) or if it turns out nobody knows you propose a method for figuring it out, put it out there and see if it appears sound (which was why I posted the article and keep trying to get a fruitful discussion going). As for me I'm in the final stages of installing a pool with venturi skimmers (long in use in commercial pools), carefully sized pumping, gentle curves and a low back pressure filter and MPV (off the shelf from Pentair, nothing special). The robot will be a pressure driven 380 but because the pump is variable speed I won't need a boost pump (saved $$ and much more efficient due to the Intelliflo's ECM motor). The whole system will run at 16 gpm when filtering, which given the head will result in power consumption of less than a quarter of a standard single speed pump. It pops up to 40 gpm when heat exchanger (I'm using hot water from the same heat pumps that heats and cools the house to heat the pool) comes on, but that is rarely going to be more than 3 hours a day. Even if I ran the system 24/7 my payback for the pump is no more than a year. If it turns out running less than that is possible all the better. So please excuse the long post but if anyone is interested in this kind of thing and wants to keep bouncing ideas back and forth I'd greatly appreciate it. Problem solving is a team sport.

No local dealer can compete with the online dealers' hands on instructions either. And actually I haven't seen a web site selling softeners that doesn't have toll free telephone support for any problems their customer has with the products they have sold them. Some offer it 9-12 hours a day and 6 days a week. No local dealer does that. That provides a DIYer service at his convenience in his spare time with no cost and he knows it was done right because he does it himself. And he saves substantial service charge and 15 minute billing costs. He also gets online parts prices which are usually substantially less than the local dealer sells them for. And he gets service in a shorter length of time, or the same length of time, it takes a local dealer to get out to his house. Unless of course the local dealer is sitting around waiting for his phone to be rung by someone that is dependent rather than self sufficient and independent. Also, In many cases, the equipment sold online is identical to the local dealers' equipment unless it is proprietary. In that case the customer is then locked into that local franchised or exclusive territory dealer and has no other choice.

Barco, I just ran across your post here and thought I'd give you some advice on your situation. To start with, I am the National Service Manager for UltraPure Water Quality, Inc. The first thing I'd like to point out is that even though your UltraPure is plumbed into a tee on the suction side of your pump, this is not a true standpipe installation as the tee is above the pool waterline. Because of this, you still require a check valve to be installed, which brings me to my next point. Our check valves are designed specifically for Ozone gas, meaning that they have Ozone resistant Viton seals and stainless steel springs. The purpose of the check valve is not to keep water from entering the Ozone generator, it is there to keep the water in the pump from draining when the pump shuts down. These are custom made check valves which will handle the Ozone gas for a number of years, but as with any check valve they will fail at some point. You failed to mention a couple of critical points before telling people to stay away from our company and it's products. 1. How old is your UltraPure system (any check valve will fail at some point)? 2. Who installed the system, and why were these issues not taken up with them? 3. Did you try calling UltraPure to diagnose your problem? If this is a legitimate problem with our product and not the installer we will be happy to find a resolution. We have been in constant business since 1982 and pioneered the suction-side injection method for the Ozone delivery in residential pools. When installed correctly, less than 1% of air/Ozone mixture (by volume) is introduced through the pump/filter/heater. This method of installation is far superior to a pressure-side "venturi" method for the following reasons: - We inject Ozone into the highest pressure point in the system, between the pump and filter. This forces the Ozone mixture into the water with the use of the pump impeller. - Most of the oxidation work is done in the pump and filter, also degreasing the filter in the process. - The small champagne bubbles that exit at the pool returns have mostly reverted back to Oxygen by this point. By using a "venturi" type injector on the pressure side of the pump none of the above benefits are possible. There is very little pressure to force the Ozone into the water, very little contact time for the Ozone to effectively oxidize the water, and the resulting "live" Ozone that exits the returns can "bleach" the sides of the pool above the return jets. We believe in our method to the point that we will not offer our products for a pressure-sided installation, that is the "old fashioned" installation method we did a number of years ago. I can assure you that your problem is not common as we sell thousands of units per year and have a warranty rate of less than 1% (manufacturing standard is 5%). We are the market leader for Ozone systems for residential pools and are a very respected manufacturer in the pool and spa industry. Our products have been tested and proven for effectiveness and reliability by ourselves and numerous third-party resources. We do not manufacture products that do not live up to our claims, which is why we do not and will not manufacture any Corona Discharge (CD) Ozone generators. Please feel free to contact me with any questions or concerns and I would be happy to help you out. to WOMANOWNED, Our pool units, depending on model use either 1A to 2A. You are only running 1 or 2 UV lamps (similar to fluorescent lamps).
