Yes, venting properly will remove the need for chemicals in the holding tank. In a previous boat we had a horrible smell from the holding tank. Tried a lot of different chemicals, no help. Installed a Groco Sweetank that pumps air into the tank and no more smell for the 8 more years we owned the boat without any chemicals at all.
