How to Build a Wet Dry filter

In this ebook I explain how to build a wet dry filter sufficient for reef tanks up to 100 gallons and cichlid tanks up to 125 gallons. If your aquarium is larger than that, you can build a bigger wet dry filter using the same concept explained in the ebook. This wet dry filter is built using a 20 gallon long and a 10 gallon tank, It cost about $50.00 to build. The wet dry filter will need a water pump, you will need to purchase that separately.
