Base Rock and Live Rock

[skozzy]

I bought a few kilo's of base rock the other day and some more live rock
from the one shop, I was wondering what the expected time would be to see
these base rocks getting signs of coraline alge.

For the lighting in the tank I changed from duel daylight fluros and 150watt
metal halide to 4 hagen power glo's and 2 marine glo's. I changed the
lighting recently because it was found that the lights were causing all my
bad alge problems in the tank.

And my other test is one base rock and one live rock in an esky with an air
stone sitting outside in the direct sun. There is green alge growing on the
side of the esky and the base rock showed signs of green staining but no
alge. Should I ever expect any coraline alge to show up on this base rock or
is it a doomed experiment. ?

Coraline alge will show up but it will take time. Most coraline algeas
do better under lower light rather than bright, so the rocks you have
out in the sun will take a long time to get covered.

Wow... Ok, so the experiment I have running would need to be covered with
some type of shade cloth, or just take it out from direct sunlight and have
it in a lightly shaded area ?

When I bought my used 55g setup, all the rock was a dull green color. When I
flipped over the rockwork, each piece had beautiful purple coralline on the
underside. I was able to arrange the rockwork when I got home with a lot of
color.

I've never tested any LR outdoors. It is pretty pricey stuff, and I prefer to
keep it in my tanks.
