When we commissioned our present boat, we took advice from Chris Coburn of Lee Sanitation. He recomended us to fit a Vacu-flush loo with a remote holding tank, and said that if we provided enough ventilation for the holding tank (two vents), then natural decay by aerobic bacteria (which are killed by any of the blue or green products) would take care of the system with no additives. So that's what we've done, and it works. The only time we get any smell out of the system (through the external vents) in when (a) the tank's nearly full and (b) the weather's warm,and then the smell only occurs while the vacuum system is actually pumping. We did experiment with using blue for a few weeks, but it made absolutely no difference to the effect, so we stopped using it again. We are live-aboards and need to pump-out our tank every two or three weeks. Mike Stevens narrowboat Felis Catus III web-site www.mike-stevens.co.uk Defend the waterways.
