I have a question for you Crystal Red shrimp people out there. Here's the deal, my house believe it or not was built over a small peat bog. A new addition was built in the 70s so there is access through a basement widow below this new addition, a crawl space. It is entirely closed off with foundation going down 5 feet and therefore a completely sterile environment being that it has been closed off for 30 years plus from the outside. In this area, a big peaty mud hole has developed that never freezes and never dries up, about six inches deep and six foot around. The water in this is ph perfect for CRS. I'm wondering if I were to run lights, heater and sponge filter with air pump out to it if I could grow CRS in it. I would simply have to feed them and monitor the water temp. My question is about the actual water itself, it is perfect except it is very muddy and full of peat. How sensitive are CRS to junk floating in their water?
