Disclaimer before you bash me: I am a believer in BBB and had a pretty good year last year. I will keep that up...when we are home. But:
A neighbor in the RV park loves his Frogger system because he is able to RV a lot and not come home to a green pool. He knows it costs more, but he can stay on the road more. As earlier posts show, that is our goal: stay on the road while we can as much as we can. But, we need the pool open because we do a vacation rental and use it when we are home.
Before you say get a neighbor: we live in the country. We have no neighbor than can do the BBB stuff. We have a friend (with disabilities) that can swap out cartridges. She cannot haul buckets of bleach and do testing. We've tried. Luckily we live in an open area and the pool rarely needs vacuuming. I just need a way to automatically keep the pool clear, even if it costs extra money (within reason). CYA buildup is not a huge problem because the pool is only open from 1 June until Labor Day...maybe longer if it stays warm and there are no hurricanes and we are on a well with plenty of water.
I saw an older thread on Frogger. Wonder if there are more recent experiences with it or other automatic systems? Again: it has to be simple...screw out the old cartridge and put in a new one.
