How did you get rid of the cyano on your sand bed?
I would love see your sump pic , TOTM
Yes I vacuum the sand bed once a month during the water change.Well done!!
congratulations for your marvellous tank.
It is very interesting to note you have kept good values of PO4 with a shallow/medium sand bed over 5 years.
Do you often vacuum it?
