Q: I have some questions that have emerged now when we've used the ECOsmarte for a while:
      1) What do you do with the slime on the walls?
      2) What is the normal oxidation time in hours per day for a 5 x 10m pool, depth 1.50m
      3) It took us 6-7 weeks to get the copper content to 6.8. Is that normal?
      4) Is there a pH electrode till install for automatic dosing of carbonic acid? 
      5) Do we need acid to clean the electrodes before winterizing?
      6) Which type of default settings do you have for a 5 x 10m pool, depth 1.5m?
      7) If you'd like to control a pump with the system do you have a relay or contractor to install along with the pump?
 
A: 1) Slime on the walls on a new vinyl pool is normally the off gassing of the vinyl liner printing. This is confirmed by the fiberglass steps-- if they are slimy you have early algae growth. As noted in the owner's manual, the slipperries are over come the first season with three liters bleach per 30000 liters water, usually every two to three weeks. Liners with dark printing have been known to take the whole first season .

2) Normal oxygen run time on a five by 10 meter pool is eight hours.

3) The normal time to ionize this pool is two to three days. Either the calcium is below 400ppm, the ph is above 7.2, or the pool has phosphates if it takes longer than one week on even a big pool. Most likely ph or calcium numbers need to be double checked. 6.6 is better than 7.0 at all times for Ecosmarte.

4) The CO2 will always deliver the 6.8 in minutes per day. 20 to 60 on vinyl pools. Those CO2 systems on the market using a sensor fail the solenoid in less than a year (dry ice is running thru it) and require monthly calibration of the sensor to operate. We have perfected the Intel driven four injection sensor and since 2002 believe we have the strongest consumer platform. The customer simply modifies the minutes per day until the 6.8 is always there. The carbonic acid is unable to lower ph below 6.7 no matter how many minutes you inject, according to science. Only acid rain can get it lower and the CO2 even buffers those sites as a rule.

5) We clean the electrodes at opening and once during mid season, leaving them in the pool all winter which often finds winter moss/fungus on them in the spring.

6) 90 per cent of our vinyl pools will run eight hours oxygen during daylight hours, four hours copper the day before the service or consumer will be testing the water and 20 minutes CO2 injection per day, equally split by the Intel chip to four equal injections of five minutes within the programmed pool run time. If this auto-repeat program is off on any of the numbers we modify the time after test the water. A ten kil CO2 cylinder last ten weeks, confirmed only by cylinder weight as the internal tank pressure varies by both volume and weight of existing gas and gauges give no advance warning the cylinder is empty.

7) As to maintain our CSA/TUV and UL rating on the product we encourage you to sell the customer a Jandy, Compool or basic intermatic timer as additional profit centers and program or address the Ecosmarte to run parallel. The high voltage/amperage pump relay was discontinued at both dealer request and the UL/TUV/CSA approval. Our CE EU low voltage directives would not apply with it either.

In your configurations, and pardon my lack of metric on pump kilowatts, we have seen a Scandinavian trend towards 1.5 HP pumps with both 92 kilo and 150 kilo filters-- these will result in slightly hazy water on a come and go basis .1.0 HP with 150 kilo, 250 kilo min with 1.5hp. This is as important as the numbers 6.8. 400ppm Calcium and .5 to .7ppm cu with Zero Phosphates confirmed in the pool each spring with the annual hardness test and adjustment.

On another subject, we have scheduled a pool builder training for Oct 16th, 9:30 -2PM at the Fira Palace in Barcelona and I have a prepaid room reserved for Poolkungen (the town is almost sold out) the night of the 16th, with the show opening the 17th. Our Norwegian builder is now at nearly 50 Ecosmartes, running to seem-less as is our new builder from Istanbul of all places . These are good questions David.
