RE: [AGA Member] Planted Tank Room- Central Filtration

["S. Hieber" <shieber@yahoo.com>]

Educate me, please.  What's the advantage over just using a
valves between main pump and each tank on an ordianry
overflow sump system?  The tank will get no fulluler than
the overflow and the rate or turnover in each tank is
controlled by the valve. Any one or more can be taken off
line without taking the others off.

Is the point to have a holding tank for water to age?  Why
not have the holding tank release directly into the sump?
