Welcome KathleenGray and yep that's what the DIY Aquaponics Forum is all about...finding ways of doing things the least expensive way possible and if you will take the time to read through the threads here and learn it as you go, you'll know more about Aquaponics than 99% of those wanna' bees that have their own web sites trying to convince the world they are the way to enlightenment. Enjoy.
