Steve here, I own an SG6 and would highly recommend it. Makes clear cs with no agglomeration until you try to hit very high ppm in the 20 range. If you stay within the 5-10ppm range, about half way up on the ppm dial, no problem, beautiful clear cs. If you want to hit the 20ppm range simply clean the electrodes about halfway through the process and you will have a good clear product. I have seen awesome results using the cs made by the SG6. Many people that buy my product and folks I give it away to free always comment they can't believe how well it works.
