I hope this isn't bad forum etiquette, but we need to get this question marathon rolling again.

Q: What are the ideal conditions for a coral reef? (in regards to water temp., salinity, turbidity, etc.)

[TimeLord]

An ideal temperature for a coral reef is between 68-90 degrees Fahrenheit or 20-32 degrees Celsius. For salinity it is best for it to be 34-37 parts of 1000. Coral also needs very clear water to grow so that sunlight can reach it easily. Is there any other things that need to be answered for your question?

[TimeLord]

Also the coral should be in shallow water for it to grow the best.

Correct on both accounts. Your turn

Ok. This is an easy one.

It's been a while, so I'll ask another question:

What is the use of iron to create a phytoplankton bloom in the ocean to remove CO2 from the atmosphere?

Iron is a limiting nutrient in the ocean, so adding it will cause phytoplankton to grow quickly (bloom). They'll photosynthesize and remove CO2 from the atmosphere that way. The bad part comes from when all the algae die and cause hypoxia instead.

I was looking for a word, not an explanation, but close enough. (Iron Fertilization is what I was looking for)

Your turn.
