Updated photo of the large tank. More monstera now, as you can see. 😊 I have “upgraded“ the previous 6000l/h ATK pump to this one: https://aqualight.de/easypumpe-24v-dc-sixpole-ep-12.000l/h-mit-digitalsteuerung Its 12 000 l/h so the water flow is significantly higher whish is very nice indeed. However, the new pump is also somewhat noisy. I find that to be quite annoying. The old ones where almost completely silent, so maybe I’ll buy a higher flow ATK someday. Expensive though… Also I bought new bulbs for the MH light. That made such a massive difference. I have realised that I have been focusing too much on light temperature, and to little on colour accuracy when I have bought bulbs previously. These are 4000 K which is less than the “correct” 6000 K. But they have a CRI (colour rendering index) over 95, which is very good. It’s probably the best bulbs I’ve ever had. Photo taken with iPhone 12 Pro, and edited in Lightroom. The dynamic range of this picture is the perfect use case for computational photography. It’s impossible to expose correctly with a “real” camera, and since the fish move around so much, multi exposure HDR is not really an option either.
