‘Adjustable Stand’ is the stand specifically designed for ‘Prime Pro’ and ‘Prime Pro EX’. A pair of 15 cm stainless steel tubes can extend Prime and Prime Pro up to 20 cm (e.g., Prime 600 + Adjustable Stand = Min. 600 to Max. 800 cm tank). Life Aqua Series – ‘Adjustable Stand’ fulfill the needs for your unique aquarium tank of different size. In this second edition, the adjustable stand can fit any standard and non-standard tank. Also the height of the stand changed to 20 cm to improve the color mixing quality.
