New From Sam Pask Design - Project:Aquarius, the easy to use Aquarium Water Change Device, Project Aquarius is an ad-hoc solution to the many problems encountered when water changing a fish tank, solving problems like carrying heavy water buckets, starting and controlling siphons, replacing tank water and filling large containers from the sink. Project:aquarius is designed from a series of easy to get hold of components available both on the high street and or online.
Project:Aquarius is designed to be fully customisable to suit the users fish tank, the main component behind any project is the water containers, The best i have found are plastic jerry cans, which come in a variety of sizes varying from 5 litres up to 50 litres, ideally you want a container that can hold the amount of water that you need to water change in one go to save you making multiple trips.
A recommended water change for a tropical or cold water tank is 20% every two weeks so ideally a barrel that holds 20% of the tank contents would be perfect. so for a 60 litre aquarium needs approximately a 12 litre water change and a 100 litre bucket needs a 20 litre. Marine fish tanks require 10% water changes every week so the container size can be worked out the same way but with 10% buckets instead of 20%
The tank i created this project for is a 50 litre tropical tank so i purchased two 10 litre plastic jerry cans, one for tank water and one for clean water. from my local aquarium.
