I have a pair of pools connected by a spillover but with essentially independent pump and filtration systems. I am slowly trying to reduce the amount of maintenance. I installed a SWG recently and changed the 30 year old single speed pumps by variable speed ones. One recurring issue is cleaning the DE filters. Our pool gets a lot of debris from trees, etc and it is one of the tasks we dread. We have a non-functional gas heater that we have been meaning to remove and I was considering putting a sand filter there in series with one of the DE filters. The thinking is that the sand filter could take care of the main cleaning and be simpler to maintain, the DE would be in recirculate (bypass) for the periods when the pool is not being used as intensively (we don't close the pool). Are there any problems with this approach? Are the tagelus filters a good option? Any other suggestions?
