Deviating from the Chemi-Clean instructions usually doesn't work. The Cyano comes back.
Oh,I'm pretty sure it will be back anyways....no matter what.

I've learned to just live with the fact that this stuff will never die.
I introduced some into a QT tank while adding sand from my display.It seemed to grow out in there pretty quickly and started on the glass.
I basically turned the lights out for a week and just topped of the tank daily.
It looked gone........but came back.

So cutting back light's IME do absolutely nothing to cyano.The tank is in the basement,pretty much no light at all.This tank was not even fed anything...ever....did nothing.
I siphon out as much cyano as I can weekly in the display.It often stays right on the sandbed.
Tank 9 months old (55)gallon
I use RO/DI with 0 TDS.
My nitrates are undectable and always have been.
I don't even have any nuisance algae to speak of(just bacteria).
My phosphate was like .07 checked twice with the Hanna at the meetings.
I have a Maxijet mod that pushes 1600 GPH and a Maxijet 1200.
Just added a 70 gallon sump with a ASM G-2 skimmer to the system.
That's pushing at least 600 gph through there.Time will tell with this now implemented.I'm hoping to strip the water of any nutrients that feed the cyano.
For now I've just learned to live with the fact that cyano and SW tanks go hand and hand.Perhaps as time goes by and the tank ages this will go away completly.But......I'm not going to hold my breath on that one.
