Zoone

I guess my AB 10000 bulbs are quite good for the plants, but i still wonder about the PUR for it as Aquamedic wont tell the Lumens value.

Now i have ordered two new bulbs Giesemann Tropic, i can guess that the PUR will be lower because the light in the green and yellow part of the spectrum but i will still have light enough, 150Wx2 over 325L.

There is two reasons for the new bulbs, the spectrum is more even distributed and i think that will make the tank look nicer, and the fact that i am a bit tired of the sticky bright bluish stray light.
