Look at these two photos
This is part of what will be my quarantine, the detail is that I get chaeto algae and had nowhere to put it, place it there with some rocks and I put a makeshift lamp
What is interesting here is where they see this as a black spot in the picture is actually green alga, ie this grew below where it gives a strong flow and very low light, grew nothing which gives lots of light but little flow
I know I have given several times, but for me it's interesting how you can use this unexpected result, I thought the thing flow and the light was more even, but I do not
Well just wanted to share this experience and see if we can take advantage
