I have the exact same AquaFX Barracuda as you do. I bought a Flush Kit for my system too. I flush it for about 5 minutes after every use. It's a great little system. Mine is also 50 GPD. I found it great when I had a smaller tank, but for my 90 gallon I am looking at upgrading. After 2 years (or has it been 3?) my 50 GPD RO membrane is finally starting to get used up, so I will replace it with a 150 GPD membrane. Upgrading is simple, buy the 150 GPD membrane with the 98% rejection rate, and buy a 150 GPD flow restrictor. You will find the flow restrictor on the good water line. If you pull the line off it will be stuffed in the end of the tubing. So, just make sure the rating of the flow restrictor and the membrane match and you're good to go!
