The cat is about 10 inches long right now but ive only had him 2 months....grew from 2 inches. Ive had one before grew him to 24 inches and sold him to a guy with a much larger tank.
yeah thats why i suggested a boiler set up ,initial start up costs a bit more but will pay for its self in a year depending on gas prices , for filtration id go for a single large sump built in at one end then use a pond air pump and run large airstones or possibly build large air powered filters to supplement the sump
