Closest real Crystal to a '7 gallon': the 7.43-gal model. NOTE: this size uses a built-in SIDE filter chamber, not a rear chamber (Lifegard's true back-filter Crystal AIO sizes are 4.14, 10, and 24 gal). Volume 7.43 gal total; display volume not separately published. Ships WITHOUT a light. Includes a Quiet One return pump; stock GPH not published by the manufacturer. Filter-chamber internal dims not published and no reliable community figure, so chamber left null.
