A local tilapia breeder had a little workshop today and myself, Ernie, and my brother were in attendance. One of the things the breeder was saying was to use 500 mg of Vitamin C per 50 gallons of water to remove chlorine and chloramines.
Sounds too good to be true, right? She swears by this method though, and uses normal tap water without any filters or other chemicals.
I'm definitely going to try it.

Another interesting thing was her opinion on the minimum water depth you should use for your Tilapia fish tank. She recommended 36". Any less and the fish will try to jump out. I believe Ernie experienced that first hand.

She was also using plastic garden screen as bio filtration material as opposed to the plastic specifically made for aquatics.. It's sold at most hardware stores and you can find it in 15' long rolls. She just buys some of them, leaves them rolled up, and drops them straight in a 55g barrel. Very easy bio-filter.
