This weekend, I'll drill the wall for the brackets and you'll finally see what the tank properly looks like with the lighting on.
What distance should the lights be above the water? Approximately..

Hi Jules,  Lee here but Joe has the same number of letters so it'll do  ;)  :D

Love the brackets fella, just what I would do, I certainly wouldn't go to the options list for overpriced branded brackets  :lol:

Some manufacturers give details on the recommended mounting height, if not then it's play by eye.

You obviously don't want your lights so high that you get the cone of light spilling over the sides of the tank lighting up the carpet, coraline carpet isn't a great look  :D

There will be a sweet spot as you move it nearer where the light doesn't spill over then it depends on how you like it and your corals respond.

I assume there is some intensity adjustment in the lights too for further tweaks.

I'm totally new to LED lighting so not much help beyond that point I'm afraid, I just bought my first one.
I almost went with a new halide set up, from the local hydroponics shop mind, they're cheaper than aquatics outlets  8D

So yeah, plenty of positional testing, measuring and marking up before you sink the holes, make sure you're happy with the look 👍

Thanks:

Thanks Lee, there is another element to the position, and that is catching the light down at the sofa.
Before, when I had Halides and actinic T5's the tank being so high would let light out directly into the eyes of people sitting on the sofa at the other end of the lounge, it's an unfortunate product of making the tank appear to sit on the living room cabinet, in fact, to do any maintenance at the bottom of the tank I need to stand on a stepladder, and the tank itself is only 20" tall.
Clearly, I'll have to put up some sort of lightweight surround 1. to stop light bleeding into our eyes, 2. to inhibit the cat from jumping up to the top of the tank (you see I found her previously drinking the saltwater from the tank, god knows why) and our cat can jump four feet in the air from a sitting position!
Heaven only knows what she'll think of the brightly coloured fish later down the line, as it is, if we want to watch a nature documentary, we have to send her out of the room or suffer a scratched LED screen!

Morning Jules 👍

Your cat sounds like two of my dogs, forget watching anything with animals in, they just go into attack mode at the screen.
Heard folk say dogs can't see the tv screen, well how come they can even tell Brian is the only regular member of the Family Guy cast that's an animal then  :lol:

You might want to look into a DIY version of something like @garethwood was looking for here, @ajm83 put a link on there for a nosey, https://reefbase.co.uk/general-reef-discussions/topless-pics-please-)/msg73526/#msg73526

I'll certainly be joining you balancing on steps to do any maintenance but I'll get plenty of practice during the build and adjust anything too tricky in the process.  In tank pump placements are going to be my biggest challenge so I can service them and return them again 🤔

FINALLY got the lights on. Now you can see the tank a bit better.
I don't know why, but I had to up the red LED spectrum to get an image of what it actually looks like to the naked eye, first shots had a deep blue tint that I couldn't see.

You can also see what I meant by trying to get the tank to look like it was sat on the wooden unit.
In this shot I reduced the exposure by one stop, I think it's better.

Ok so I took out the trickle filter, sad to see it go, and not at the same time.Maybe I was relying on it so much that my nitrate production was through the roof (well, at least 10ppm after the recent test).As per your advice people, I'm now reliant on the living rock and 4x Boxtech (similar to maxspect product) in the low flow area of the sump, I'll probably put more of that media at some point, but after I've built the algae scrubber.The latest thing to happen was a brown dust-type algae throughout the tank, so I switched the lights off, did a nitrate test (ammonia and nitrite showed 0ppm) and found it high.In accordance with tried and tested methods, I'll do a few water changes to get it down, and crack on with the algae scrubber, so that can kick in to help with the nitrate/phosphate further down the line.The seneye is ordered, and a Win 10 tablet secured s/h from ebay so I can make my own server as per link kindly supplied by ajm83.Here's hoping I'm on the right track with my methods.I'll repeat what I said before: anyone who doesn't live too far from me wants to check their PAR, I'll be happy to pop down and we can stick my probe in their tank and take a reading.

Be happy to do so.
When and if I go to a LFS in Herts, I'll announce in case there's anyone in that area needs a PAR reading too.
