Hi thanks for all the replies,
I have a few pics but not the most impressive of reefs, all the corals are small but are looking healthier in the last month than they have been.
They have been seriously smothered in algae and i have let the salinity wander wildly so the frags that live there are mostly still frag sized. .....although alive, some of them only just though
I have kept tropicals for years in the past but don't keep them any more.
As far as the lights go, my thoughts were more along the lines that it is tricky to find info on whats good and whats not, and a lot of tanks that i have looked at seem to have higher wattage lighting than i currently have. So was looking for an opinion on these lights that i am currently using.
If you think that the lighting is sufficient then i will keep with the current setup, thank you for mentioning the spare one though.
