I’m looking into adding a 55 gallon remote drum for the purpose easy water changes. My thinking is to have a pump in the sump that would push water through pex pipe, under the house, into my shop and into a sealed drum and return back to the sump. When I get ready to do a water changes, I valve out the dum, empty it, refill with new water then valve it back in. Is this a bad idea? Also, would there be any benefit in adding a 2nd drum with a deep sand bed (8”) and rock that would simply sit in series with the water change drum?
