Ugh... Trouble in paradise
View attachment 219640
This morning while sucking up and cleaning the tank i found this in the center of my tank...
I removed it all and cleaned it with washing and soaking the sand in some flourisch excel. Again a good rinse and back in the tank.
For a long time i am playing with the idea to remove the sand and replace it with a small nutrient soil layer (dennerle deponitmix black) with dark 1/3mm sand.
This situation could be maybe the last drop and maybe i go ahead with that plan...
Thing is, next week is the last week at home before i start with a new job. Problem is, saturday we will be on Samos for 12 days so i have 5 days to monitor the changes....
