Hokay. Keep us posted!
Don't *faff*, dear.

Have you considered going to Kmart and getting a 15 foot diameter pool 42"
deep? A swimming pool will turn green in a week with no chlorine in it.
These pools cost some where around $00 or they did last time I bought one.
It seems that all the algae just needs light to grow.

I have considered the I idea of using pool liner LIKE material for a
sallow raceway, raceways need to be only 12 to 18" deep because sun
light need to penetrate the algae for photosynthesis and when the
algae gets going light penetration is limited to the top 4" of the
Light for photosynthesis is obviously important but in my view
nutrient ratios are also critical and something you can and have to
control (you can't control sun light in a raceway system).
Having said that, I wouldn't worry too much about raceway design until
(and IF) I found a suitable indigenous strain of algae, else it's
Best-yield non-indigenous algae with a photo-bio-reactor and a whole
new set of concerns.

You must be talking about some pretty thick algae. The stuff I seen in
swimming pools went right down to the bottom and there was still plenty of
light. I would think you could filter out some alge every week, saving the
rest to grow more.

You got to remember you're throwing the prefect pool party for
particular strain, you're buying the food, drink, and happy gas (CO2),
and then seeding it with a guests, you what it to elbow to elbow. You
hopefully will be continuously harvesting, that's the whole point!
