OK so it's pretty clear to me that i shoudn't be using the "blue" chemical black tank cleansers, because I want to foster bacterial growth in the black water tank to break everything down.
However, I'm wondering which of these 2 methods is better:
1. the "Geo Method" proposed by http://home.mindspring.com/~cbruni/index.html
. Basically this writer suggests only using some powdered water softener and laundry detergent in the black water tank.
2. the "enzyyme" approach, as proffered here: http://www.valterra.com/RV/inthenews.htm
3. the "good bacteria" approach, as proffered here: www.eco-save.com
Right now I'm inclined to go the eco-save approach, but let me know if you have other suggestions... Also please let me know if you've used eco-save.
