Commercial 'River Tank' = brand name, was independent originally, several years ago purchased by Perfecto. Built into standard tanks by fiberglass compoments siliconed (watertight) into standard glass tanks. Mine has "two rapids" and one waterfall. One large bog pocket, one small, both near the average water level, one pocketed shelf the width of the tank. The lower planting pockets get water from the "river", are planted with Crotons, baby's tears and Java Moss. Upper pocket has a drip system branched from the return water line (not stock, my mod/DIY), planted with Cryptanthus, baby's tears, Java Moss, and variegated dwarf creeping fig (attaches to side glasses and fiberglass back wall). Java Moss on the fiberglass background below the upper pocket (gets drips from the upper pocket) and the exposed portion of the water return line from the pump (ditto drips). Trying to get emersed Java Fern going again on the backing also. The two river pockets (sumbersed) have Cryptocoryne wendtii green in the deeper one shaded by the larger Croton and Zephrantes (aka "dwarf onion" - which it is not) in the brighter shallower pocket. Circulation is by a MaxiJet 1000 with a FilterMaxIII prefilter. Lighting is by 2 each 18" and 2 each 24" Tritons, 12 hrs per day. Stocked w/standard Zebra Danios (why would I want the freaks* with less salmon-like abilities?) and Olive Nerite snails (which like the waterfalls also).
This is the tank listed as LR30 in my tank specs.
*Can you tell that I do not care for the selected "long-finned" varieties of just about anything?
