Weekaqua Pandora P600 for 90cm Tank

[DeadFish]

Posting this here as well as in my journal for others to reference. When looking into this I could not find more than one thread covering this topic. Long story short, I have a Weekaqua Pandora P600 on hand as I was originally planning for an 80cm tank. The unit is 90W, 60cm in length. I ended up bumping up to a 90cm tank, so now I have the decision of either a.) running the 60cm fixture suspended about 30cm above the water line, or b.) taking ~ $75 loss and getting the 90cm fixture.

What do you think?

Hi all,
I'm going to assume that the light is plenty bright?

a.) running the 60cm fixture suspended about 30cm above the water line, or

So I'd go with that one.

Yep. 90W, I think 1000 PAR at surface of the water @ 100%.

I think it depends on what plants you want to grow. For example, some plants need high light to show their best colours.

I am using a P900 and a WRGB2 Pro both running at about 80%+ in my 90P tank and the amount of light is 'just about right.'

I’d go with option A too. Hang it a little higher. You could always do an island style aquascape if worried about coverage.

Not sure you would need to go 30cm "up" for one thing.
Difference between a 80 and 90 cm tank isn't that extreme.
Like 2" on each end.

Start about 23cm off the water line
