Re: Solution for Septic Field clogging Long Term
You have a good plan. The Hydrogen Peroxide is a replacement for the Sodium Percarbonate for breaking up the biomat. The advantage of Hydrogen Peroxide is that it doesn't leave behind salts which make the hardpan worse. IMO Sodium Percarbonate works really great the 1st time it is used, but each time it is used it becomes less effective because of the salts it leaves behind which contribute to hardpan. So I suggest not using Sodium Percarbonate more than one time. I have 4 gallons of 30% hydrogen peroxide on site for the next time my field clogs up.
Aeration is great for the D-Box and for septic Pits to prevent biomat. IMO, NEVER aerate a standard septic tank, or it will just send sludge right into your septic field, even forcing it through an effluent filter. Installing seepage pits at the end of your field lines is a great idea, and another great place for an aerator. IDEAL is the gray water processing for the washing machine to keep all of those salts out of your leach field. Excellent that you are taking car of this.
I have not had any problems with the lime-sulfur, as it saved my bacon when the Sodium Percarbonate no longer worked. I also don't know of any other approach to solve the hardpan problem. Septic Revive(tm) uses a different chemical for the hardpan, but I have not looked into this because lime-sulfur is working for us.
Best to you,thanks for your report,
