Look into a constant automatic water changer. Then all you're doing is cleaning filters, and if you're overfiltered enough than you only have to do that once every 2-6 months.
Basically, you drip water in (I would use one or more raindrip irrigation drippers, you can get them in 1/2, 1, 2 gallons per hour) and have it overflow out to a drain. You'd only need 1/4" tubing to each tank. You could get a filter that removes chlorine/chloramine, or you could use the output from an RO filter.
