It's the end of my first season and I want to clean my DE filter (hayward DE-3600). From what I've read this is what I need to do:
1) Have a bucket/ container large enough to hold the entire assembly
2) #1 Add some TSP (tri-sodium-phosphate) to the water or some electric dishwasher detergent to the water and soak the grids for 3 hours – this will ‘de-grease’ the membranes and is the first step in cleaning them, rinse with hose and get ready for step 3.
3) Dump the container, refill with water and add muriatic acid to the water so that you have a 10:1 water: acid mixture and soak the grids for another 3 hours, this will clean any calcium off of the grids. Rinse grids again and reinstall them in the filter.
4) Now, run pump and bleed off the air from the filter and add 100% of the DE the filter calls for.
Here are my questions:
Anything steps I should add?
Should I clean it now or wait until next year?
Should I add the DE now or wait until the opening next year?
Are there any parts I should replace while I have the filter open?
Where can I get Muriatic Acid?
thanks
