Canberra recently gave away $444 million for Barrier Reef funding.

The Barrier Reef gets 80,000,000kg nitrogen a year from cane fertiliser , triple the normal healthy amount from bird and fish waste. Qld cane-farm rivers have around 400 micrograms / litres nitrogen where 200 mcg is the danger level.

Electrolysis of sewage is claimed to remove Nitrogen at 240g / 1000 litres per Kwh . Solar power costs around .25c over 20 years cost of panel installation or $500 per Kw capacity. Qld cane-farm rivers outflow is 16 trillion litres /year. If electrolysis is installed in drains from cane-fields then the cost seems to be $3mill /year for 20 years fitting solar equipment of 120,000 Kw capacity.

There are 2.4 million Reef tourists a year staying a couple of nights and 3000 farmers pay for 80,000 tons of nitrogen fertiliser. A small tax on tourists and farmers pays the cost of electrolysis and bureaucrats .

A bit of specific water-control by drainage weirs might be workable for electrolysis.

Yeah. Let's have more taxes to put someone else out of business, and 'cure' a problem that doesn't exist. Let's root the tourist industry as governments are rooting every other Australian industry with taxes and ecomania.

Tourists will see that white Ausralia includes corals and get used to it.

Yer, but white is nice. That's why all humans have white teeth.
Milk is white, except for artificial colouring if added.
Some knights are white, except during the night, in which case white knights become black knights till the morning.

And over in the US, they have a very famous building renowned, and known as the White House.
And a blond white president.
And white snow covers much of the ground through the winter months.
And further to the North, a rotund old man in a red suit, sits astride a few rain deers and wears a white beard all year round, he is also renowned for his penchant of climbing down black chimneys on Christmas Eve.

White coral should not feel too lonely then.

Blackbeard with red Rudolf ? Parrot fish with white teeth eat coral algae which is gay rainbow . No parrots , no carrots.

Sadly , the coral will stay white. And fish skeletons. And dead sea gulls. An educated person tells me that the Nitrogen is too dilute for electrolysis to work. Tourist operators will go white in the face, in the red at the bank and have Black Dog.
