Groundwater occurs in two essential types. Unconfined groundwater occurs when the circulation of subterranean water is not confined by the presence of relatively impermeable layers (Figure 8m-2). The presence of an impermeable layer beneath one of these groundwater may cause the formation of a perched water desk. These features are elevated some distance above the floor’s most important water desk. Springs that circulation from underground to the Earth’s surface are often formed when a perched water desk intersects the floor.
What is missed is the fact that an aquarium with proper circulation ought to have more than satisfactory dissolved oxygen, not just for the micro organism, however for the fish.
Proof of that is the very fact I’ve achieved higher bio filtration with comparable fish loads with live rock (marine only) Below water as I have with wet-dry filters bio balls.
I also have achieved comparable outcomes AND Higher with large sponge filter (typically positioned in the sump) and especially with Reactor/Fluidized Sand Mattress Filters!
An efficient means to deal with water hardness is to mix a water softening system with an underneath-sink reverse osmosis filter. The softener will take care of the undesirable minerals, producing smooth water for hygienic purposes in the whole Home Drinking Water, while the under-sink RO filter removes dangerous contaminants in your drinking and cooking water. It is a well-rounded system, as it targets both types of impurities whereas being more inexpensive compared to a whole-home RO system.
