They look really good! Do you know the spread of them? My tank is much smaller than yours (90cm x 50cm bottom dimensions) but I feel like I might still need two?
I've not actually measured the spread, but the lens makes it pretty wide - much wider than you'd expect - to the point where I might have to fashion some kind of deflectors for them, as there is a lot of light spill at the height I want them. I tested it by hand over a 600 x 400 tank, and it covered that from about 250mm off the surface.
I'm not sure you'd want two on a 900, but it depends on how you are mounting it, as to what flexibility you'd have in terms of height.
Looking forward to seeing them in situ with the scape. When do you think you might set it up? I know this is a very demanding project!
Ah, as I said in the first post, this is a slow burner, I want to take my time and get it right and try and enjoy the process, as all my previous set-ups have been a bit rushed.
First stage is getting the tank, overflow box and pipework in place. This means carving the bloody wall out again, as the return pipework in the rear left corner projects out of the back of the tank about 60mm, and I want to tank around 20mm off the rear wall, so that pipe is going to have to go partially in the wall!
Then I've got to set up and test the auto-water change system, and install the cabinet electrics, doser and ATO tank/system.
Then I've got to install and fit-out the sump and wet/dry filter system and get the trickle tray working right for my chosen flow rate, and install and set-up the fleece roller. Then thoroughly test it all it as I've never ran a sump set-up before.
Theeennnnn . . . . I can finally drain it all and think about scaping it . . . .
sigh 😅
