Thanks Tim :)
I like the idea of the AI lights as they don’t require a separate controller, and they seem to have a good reputation. As you say, a pair of 26s would be needed to get good light distribution over the whole tank.
I’m still trying to work out the tank scape plan. It will not be conventional. Probably I will have 2 or 3 set-pieces, each with one species of coral and some appropriate fish. Perhaps I’ll start a new thread as my ideas come together.
Cheers,
Paul
The interface is very good, a con for the xr15 is the piwer packs are massive

Get that thread going
