@bolt,
They clearly needs someone out from the crowd such as this forum. Consultation and tutorials. It cant be much more expensive or difficult having 3 or 4 of such setups in a public aquarium center.
Anyway, fert regime wise, I do daily dose very lightly of liquid fertilizer (12-15 pumps of macro+ and 8-10 pumps of micro+) and jab in root tabs every 3 months or so.
