sump light

[RJAG]

what do you recommend, should the sump light be on 24/7 or just at night or
even just when working on the sump (top off and water-changes).

I run mine opposite to the tank.

Do you have anything alive in your sump? Do you keep live kelp there?
If so, it would be smart to run lights opposite to your tanks lights.
This would smooth diurnal pH swings related to photosynthesis.

If there is nothing alive in the sump the light is just for you,
so preserve electric energy and keep it on only when you need it.

I just have one chamber of sponge and three of media. the last is the
return pump section with a prizm skimmer which returns to the previous
chamber. I recently tried some calerpa in the last media chamber and a
piece in the live rock. both disappeared very quickly.

Then no light is needed.

I thought that calerpa was a weed and would flourish in the tank or sump but
a piece kept in the sump just disappeared and another I placed in the main
tank got blown away in the flow never to be seen again. this time I'm very
slowly acclimatising the plant in it's packaging and eventually moving it
into the sump final chamber.
