Posted last year a few times during our build. Then forgot my login and had to create new account. Need to add my info but we have 18x33 saltwater. Here is my latest addition- a custom fountain!. Just added an extra line to the return and control it via ball valves, so we can adjust the flow. Kids love it and it only cost me $20 to make it! Let me know if interested and I can send pics of the plumbing. This thing was a breeze and only took 1 hour to make. Happy Swimming
