Sand Filter W/ Good Water Flow In Recirculate But Almost None In Filter
When we just recirculate the water there is great water flow. If we turn it to filter there is little to none. Help please! We did shock and tested the water the next day and all was normal except the pH which is high. Thanks for the question First, I'd like to have your complete chemicals readings: Chlorine CYA (cyanuric acid/stabilizer) pH Alkalinity Calcium Hardness Metals (iron and copper) Total Dissolved Solids It makes troubleshooting much easier and the process of clearing up your pool will go much faster. You can get this done at your local pool store. Without these numbers I'm just guessing at what the problem is with your green water. Next is the sand filter. These are some things to check: 1. Make sure there's enough sand in the filter and it's at the right level. This is called "freeboard" which is the top of the sand to the top of the filter. Your filter manufacturer should have that information. 2. Using Baquacil and/or similar products can "gum" up your sand 3. The pool motor impeller is not gunked up with debris 4. Pump basket and skimmers are clean 5. Back wash the filter This post is very applicable to your situation: Do I Have Sand Filter Or Pump Problems?
