Solids should settle to the bottom and they must be pumped out periodically. They should not go out into the drain field. If the tank is sized right for the flow, the effluent should be rather clear. Else, the organics in hte effluent will plug up the space between the soil particles around the tiles. Eventually, they'll gunk up the soil around the tiles and the tank liquid will just exit the vent.

Grease and fats are a problem, so keep them out. They float and will plug up the soil around the drain pipe. So, plenty of dish washing liquid keeps them solublized, so the fats can be broken down. The dish liquid gets eaten by sulphate reducing bacteria.

Rid-x is just enzymes. The bugs in the septic tank do the work of breaking things down with their own enzymes. It could be that you could use one of those products, which are cultures of bacteria. Those aren't normally needed at all though. Only when their's almost no toilet flow are they warranted. In a good septic system, those bugs die and are what the solids on the bottom are composed of.

What exactly is the problem?

None yet--it's a recreational pty and I suspect that the septic may be unconventional. There will be no clothes-washing or bathing, just the toilet and sink, so there won't be a lot of waterflow except for occasional gatherings. I intend to avoid grease and bleach already. The main thing would be the toilet paper, and I already have Scott.
