Radion help please

[Jakeyjake]

Hi I have just purchased 2 xr15 freshwater radions.along with 2 brackets.could anyone advise what percentage I should be running the lights at when switching over from 2x45w HO T5 bulbs ? Aquarium is 100cm long and 50cm deep

That's a hard one to answer definitively...I'm guessing that's medium light see chart below.

I have one over a 60cm wide shallow tank that's only 25cm in height.
I've got it running at 50-55% at 6500k, 5hr photoperiod with a 30min ramp up and down either side, tot 6hrs

I'd start lowish, around say 60% and take it from there...better that way than bombarding your plants with too many photons and causing an algae bloom.

If you have a access to a PAR meter happy days...

Thanks.I have adjusted them to 60 percent.i loaded the planted tank programme for now.will look into programming my own soon.

Instructions aren't very in depth.how do you adjust the kelvin ?
