| thanks for bringing this up.
after re re re re re reading the threads last night ... i have removed the downward pipe in my RDSBs. i guess we both walked away with the same understanding. i have no intention on removing either of my RDSBs (may even add another), i think that your staggered cycling of the buckets is probably an excellent way to go about removing them though.
i will be changing the sand out on a yearly basis though. i will do this by adding a new bucket of sand about 2-3 months before removing one and replacing the sand in it. that way ... i will always have 2 RDSBs running in my system.
