Dino/cyano to heavy to suction?

[Red2143]

Sand bed is covered in clumps of cyano and maybe some dino. When I suction the sand, those clumps always fall back down. Is there any way to remove?

Had the same problem in my tank, what helped me was a good clean-up crew. Placed numerous hermit crabs, Turbo snails, aster snails, and a couple of emerald crabs. They did the job for me. The tank is all clear of that brown cyno crud.

While syphoning through a typical sand/gravel vacuum, the 2” syphon tube doesn’t have the suction you may need. Take the tube off and use the 3/4” hose to suck out all of the cyano. Then add chemiclean.

Don't you suction a lot of sand too if you use just the tube?
