All contracts for aquascaping maintenance are a one year minimum. When you buy the package this is not included in the price however the first month of aquascaping and maintenance is. (A package for a 58 gallon (36.5L x 18.5W x 21.5H) with virtually everything is the first option and is top of the line, state of the art equipment). Then typically it takes 1 - 2 hours each visit for aquascaping and maintenance. Visits are once a week, with three two week intervals per contract at my discretion. On a 75 gallon setup, (dimensions are 48.5L x 18.5W x 21.5H) or a 72 gal. bowfront(48.5L x 18W x 23H) maintenance and aquascaping is once a week per month, one year minimum. All chemicals, fertilizers, filter material, replacement of fish and plants, are included in the aquascaping and maintenance. Automatic feeders and dosers are included in the package and you may choose to feed the fish yourself or not. Hours that I will aquascape are Monday through Friday with time slots available each day.
