Thanks Dave,
I will do at some stage.
I have 400W radiums right up to the glass- or very close, but most photos are taken with blue tubes. This shot has some white/ pink tubes compared to usual.
When the halides are on during the day, there are too many reflections on the front glass to get decent photos.
To get the whole tank in, I need to take a shot about 20ft away. I can focus at the front of the tank, or at the back.
I guess there is a lens to get a greater depth of field, which would get everything in focus…. not sure which though.
I'm thinking of switching to a T5/ LED Hybrid. You can see how a pink tube brings out the pink hyacinthus on the right, so the T5 colour options are very appealing to me….
