“WOW!!!  I can’t express how pleased I am with the water in my swimming pool after treatment by Monarch Pool Services.  I’m a water quality professional and have spent 27-years managing laboratory testing and water quality services. I know that balanced pool chemistry is essential and dependent on managing calcium and total dissolved solids (TDS).  My pool is less than two years old and both these parameters were out of control and required fixing.  The advice from local pool stores was to dump the water.  However, this option was unacceptable to me because I would be refilling with local water supplies with elevated levels of calcium and TDS (these parameters in tap water are safe to drink but undesirable in pool water after evaporation).  Water treatment using Monarch’s state of the art mobile filtration system was the best option. After RO treatment, TDS levels dropped from over 2400 ppm to below 500 ppm and the water in my pool is crystal clear.  My pool will not need water treatment again for three to four years. Unfortunately, over time all pool water will need to be treated or replaced. The entire volume of water in a pool evaporates in one year because of the heat (about one foot per month) and calcium and TDS become more concentrated over time. Monarch Pool Service is the only option I would consider for treatment and I highly recommend Dwight’s service to anyone that owns a swimming pool. Dwight provided excellent customer service and was very knowledgeable about water chemistry and RO treatment.  Don’t hesitate to give him a call.  Like me, you will be delighted with your pool after he finishes treating the water.”

“Dwight and Stephanie, just wanted you to know how happy I have been with your services! My pool has never looked better. Even during the hot summer months you have been able to keep it crystal clear! Your service and attention to detail have been outstanding! I would recommend Monarch to anyone!”

“Monarch Pool Service just completed processing our pool water. Wow, what a difference! I thought the pool water looked clear before …. wrong. It sparkles now. Monarch’s process is quite impressive. Dwight took the time to explain (show off) the equipment and process. It’s all self-contained in a medium size trailer (generator, massive RO filters, and other cool water treatment stuff). Very impressive. Dwight knows his pool chemistry. It took Dwight about an hour to set things up, then turned it on and it ran independently for about 12 hours. Dwight was able to monitor remotely. The next day Dwight and Stephanie returned, took about a half hour to pack things up, and set the water chemicals … great customer service … job done … reasonable price … pool sparkling = very happy customer.”




“Mr. Barber – Every once in awhile you reach out and then find via the response received that you have found an excellent company. Put a little more simply, thank you very much for your helpful reply. Phoenix is obviously very well served. We will have a look at Reverse Osmosis companies in our area. Best Regards.”
