Wellll just how much solids are you talking about?????
A lot of us use the geo method and it seems to take care of any problems.
Plus when we dump, we use the flusher "real good" each time. Also make sure you have plenty of water in your tank when you dump. That helps everything slide out better.
In case your not familiar with the geo method---it's pretty simple. I use calgon water softener and any cheap laundry soap.
