Ok, like always I am on the quest for automation that is cheap but still effective. One of the biggest pains is usually water changing. I plan on plumbing in my next two tanks I am setting up so that I can do the work easier and possibly include automation. After reading about someone autowater change that didnt involve the use of some kind of RO system(that was mentioned anyway) it became a little more appealing to me for a few reasons(one less unit to install, one less expensive item to buy, one less unit to maintain, one less fert to dose like RO right, etc. etc.). So I was thinking, if one were to setup such a system that will fill a large container daily, then at the end of the day pump that into your tanks, would a circulating pump in the storage tank be enough to 'age' the water / offgass chlorine so one wouldnt have to use dechlor (in a 24hr period)? I am trying to see if the K.I.S.S. method can be applied to water changes.
