Hiya all,
I have a Twinstar EA 900cm, which prior to today sat on the legs it came with, at 10cm above the water's surface. I had found that I get reasonable growth and kept most algae at bay at 40%.
I bought a hanging kit (from Liti Aquaria, looks great!! did a DIY copper pipe job to hang it from the shelf), and have just hung it up higher so I can see more of the surface, and so the light has better spread. My giant piece of wood previously was in the way fo the light so the back was in shadow, whereas now it's quite illuminated, which I think my echinodorus will enjoy!
The lights are now 21cm above the surface. Can anyone help me work out what % the light should be on now it is higher up, to give the equivalent light of 40%? I am just absolutely rubbish at maths!!
For today, while I worked out the height I had it on 100%, and at the new height it seems a bit too bright. I could try it at 70% or 80%, but I'd rather ask you guys in case you can help me prevent an algae outbreak
Might need to make myself some sort of DIY shader now too lols! Looks great from far away but hurts my eyes a bit when I'm closer atm. Really looking forward to growing lots of emergents now though
