Chasmodes, with this setback, the topic ended up being truncated, with the empty spaces of the photos, but, what can be done? Living and learning ...
I lost most of the macroalgae. The fact is that the transport took them four days and when they arrived there was a lot of hydrogen sulphide gas, and this seems to have intoxicated them to the point of not recovering.
Anyway, as I said before, it is very difficult to find shops selling quality macroalgae - it is a great limitation for growing them in an aquarium ...
But we learn from the mistakes, pity that costs their lives ...
