    We are on holiday at Hibberdine at the moment and I notice there is quite a variety of beautiful plants (which I assume to be macro algae) on the rock pools. Ive seen a two or three types in LFS, but is there a reason why people dont keep a wider variety in their tanks?

    I am also interested in knowing. It surely will help keep nitrate levels lower.

    A lot of those macro algae needs intense light to survive. Others take up a lot of magnesium for example.

    Can be done and looks good. But you will not be able to keep tangs and other herbivorous fish.

    Simply because my fish eat it all.
    I do grow it in an outside tank in the sunlight that is plumbed into my main tank. Grows well and does keep the water healthy.

    That is a great idea!

    Wouldn't the direct sunlight heat up the tank too much or cause hair algea?

    Depending on the size of the tank outside in relation to the display inside. Plus the flow rate.

    Can always use shadenet to lessen the light on the tank. But yes it can still overheat easily.
