Substitute for STP (which is expensive)

It is more fun criticizing

This post has observed that in some areas of the town, there is a dearth of stp, severely affecting the water qualifty that are emptying into the Laguna lake.

About two decades ago, this post learned some cheap diy stp solution:

    1.  Water lily absorbs plenty of waste and spoiled matter from the water.  That is why drying water lily plants smell bad

    2.   DIY filtration sedimentation tank filtration:

          1.  A waterfallls for oxygenation of the water;

          2.  A sedimentation tank

          3.  Filter chamber:      rocks, gravel, fine sand, even charcoal

          UV treats waer

   3.  This post used this in a project where the effluent of a neighboring subdivision fell, and we got fish at the end of the channel from the chambers.  

The rise and fall of the land of the rising sun.

The Japan  miracle growth was orchestrated by US to show that they can help Asian countries become prosperous.   

The Japanese miracle from  1950 to 1975.  Due to inflated land prices.  Changes in accounting rules that allowed increasing prices as part of income.  Those days were heydays in the feeling of prosperity and progress of Japan.  The Japanese went on acquisition binge

And bubble burst in 1990.  The stock market crashed, the real estate prices fell down.   The Japanese faced the reality that they were not that wealthy.   From this crash, Japan never recovered.

Japan has one of the highest debt to GDP ratio.  (As USA).  Despite their seeming opulence, Japan has economic and financial weakness.

It is a nice place to visit and value for money because of the low exchange rate for Japan.
