My cheato is helping me a lot by growing fast and as a cyano magnet. I use some stainless scissors to cut off all the cyano around the top edges and tossed it in the trash. I've only ever done this once so far, yesterday.
So far I'm usuing the manual method of red hair cyano. Sucking it out with hose scraping and siphoning of sump also. I pour the water back into the tank through a gravity filter the same day I do a water change. That way I scan spread my tank cleaning and water change to last two days. My gravity filter is handy; it's a plastic 2L soda bottle with the bottom cut off, stuffed with filter floss. It was a long string loop that I hang off the ceiling above the tank. Of course I move it out of there when I'm not using it.
Changing tank habits is way easier, but I am trying to feed some growth at the moment. The cheato with the new light on it is making it easier to live with cyano.
Mine is not slimy cyano, it's fuzzy/hairbally. I couldn't stand slimy.
