Having used both eco-complete and ADA Amazonia I don't think it's going to be possible to use a product like ADA Amazonia with out doiing a complete teardown and setting up the tank again. Your just going to need to deal with the ammonia spike. Also, I found ADA Amozonia threw a lot of dirt into the water. That settled out in time, butthe tank sure looked bad for awhile.
More to the point, what are your reasons for wanting to do this type of replacement? Also, how large a tank are we talking about?
Perhaps there is a better way to correct things without a substrata replacement.
