	I curretnly have a 75 gallon (CDN) tank.  I just recently installed
	a new filter system using an EHIEM 2014 with the apropriate substrates
	in the filter to do the type of filtering that I want.  My problem
	is this:

	Before switching over to this filter system, I was using the under-
	gravel filter with two 200 gallon per hour pumps to pump water from
	under the gravel bed and then through an external filter before
	returning the water to the tank.

	I still have the two powerheads installed and they now just circulate
	water in the tank after sucking it through the gravel in the bottom
	of the tank.  I also have the EHIEM filter sucking water from in the
	tank through the filter system and then back into the top of the tank.

	I would like to feed the water from the EHIEM filter back through
	the down tubes and up through the gravel, however, I am worried about
	the amonia levels in the tank going sky high if I just turn the water
	going through the down tubes around.

	Question(s):

		Is there anything wrong or potentially hazardous with the
		manner in which my tank is set up now?

		Can I switch the water flow in the down tubes around without
		risk life and fin of my fish?

	Notes:

		The water in my tank is currently crystal clear, the pH level
		is right where it should be as well as all the other chemical
		levels in the tank.  I've been using the EHIEM for only one
		week now and the tank was in perfect shape before I added the
		new filtering system.
