    Hello all,

    I have a DSM tank, I set it up like 6 weeks ago.
    About two weeks ago, the substrate started turning blue-green, at first I tried spooning out the top layer of the substrate, it didnt worked.

    I tried to get some EM, but I need a prescription to get any antibiotics here, a friend gave some amoxycillin pills that he had, I started spraying amoxycillin like a week and a half ago.

    Cyano has reduced but it doesn't seems like I'm winning the battle.

    Any ideas of what I could do to get rid of it?

    Substrate is boiled wormcasting cut with river sand, river sand cap.

    Plants are HC, E. parvula, P. Helferi E. tenellus and some cripts.

    Regards,

    Juan

    I've had it in a tank for my frogs and emersed growth. To get rid of it I did a black-out and then raised the water level, I then siphoned out the algae and the excess water. Worked pretty good, second time most of it was gone :)

    Thanks for replying,

    How many days did you did the black-out?

    2 days, should've gone for 3 (hence why I did it for a second time). But I did have some large patches of cyano. You also need to get out the last bits in between the sand or they will grow out again.

    Use 2-3 layers of black plastic trash bags or cover with 2 thick towels etc, it needs to be really black in there for 3 full days.
