The floating hydroponic apparatus has a floating hydroponic tray having a floating base portion and a tray portion. The floating base portion is made of a lightweight cement and has floating perimeter walls along with a polymer screen attached between the floating base portion and the tray portion. The floating base portion and tray portion form a plurality of openings therethrough for the passage of liquid. An alkaline resistant coating is applied to at least a portion of the tray. The tray portion is filled with a soil mixture supported by the polymer screen so that plants can be grown in the soil in the trays while the trays are floating upon a liquid reservoir. The trays can be used in conjunction with a hydroponic system having pools with specially designed lightweight concrete walls forming a habitat for marine life.
