Need science fair help ASAP

HAHAHA i've been called allot of things, but an *expert* is not one of them... :hammer:

Never said you were....JK Just said I needed one to put on my report LOL.

Or you could do something even easier like comparing the growth rate of two different corals. One you feed and one you don't. Does fed coral A have a faster growth rate than non-supplemented coral B? Same thing for adding calcium/alkalinity to one system and none to the other. Do supplemented corals exhibit better color/growth?

What corals do well in a nutrient rich system? Will corals grow faster if I sing to them? hehe They've done it for plants.

You could also go really low budget and see which foods make copepods grow faster and link your studies to the aquaculture industry.

Good luck on whatever you choose to do.

How about the purification ability of Calcium Hydroxide? I didn't read all of the thread but If you are in high school or college this could be a big hit!

High pH, elevated calcium levels, and the Ksp of several different Ions in water, and Kalkwassar water.

Then to go even further the ability of said Ions to re-enter the water/solution if the pH were to be lowered.

Just a thought!
