This is to filter a 40 gallon long . Since I'm getting a chiller for this and will need a water pump anyway I'm thinking of using a 10 gallon tank as a filter.The 10 will be under the 40 and I have questions about safety during a power failure,filter media (sand ?) as well as the practicality of the idea as a whole. This may even be overkill for a lightly stocked 40. Could anyone recommend a good book on the subject ? or I'd love to hear your ideas as well.
Thank You
