Don't reduce the flow through the undergravel filter gradually or otherwise. You risk the development of anerobic areas in the gravel bed. A much safer way to make the transition is to remove a handful of gravel every other week or so. Just leave the UGF setup as is. When the gravel has been completely removed, you can safely disconnect it. It is always a good idea to test the water regularly during the transition to assure that you are not removing too much gravel, too soon. Brad

The Tufa ``Base rock'' around here is $4 per pound. Thats still expensive when you consider how much you need. Isn't there a cheaper way to buy Tufa?

Just a little waring, even if you do purchase "cured" rock, by the time it is shipped and installed in the tank, it will more than likely have to be recured because all the organisms on the rock probably will not survive the shipping process.
