You can dose 7 drops SpongePower every other day additional if you like to.

To treat the cyanos it would be worth a try to dose 14 ml CoralSnow mixed with 7 drops ZeoBac daily for some time. While doing this no separate ZeoBac dosage is necessary.

It also looks like the sand does contain a lot of mulm. To get rid of the cyanos vacuum the sand regular while each water change to remove the mulm and the cyanos in the deeper sand layers.

Which kind of sand is this exactly ?
