got BAD Cyano tried to do everything i cold think of to avoid using it. at this point i think i have no choice. anyone who used it i would love some suggestions.

i had an absolute cyano farm in my 37 cube due to tapwater (loooong story)

i treated the first chemiclean treatment on a tue, then another on a thur, then did a 10g water change on a sat and have had none since

ive also been keeping up with more aggresive water changes (RO only this time around) since the outbreak

like greenmako said make sure there is oxygen in the tank somehow and remove all of the stuff he said (i only left my powerheads on) and you should be fine. to my knowledge ive had no ill effects from using it

There's that ongoing thread on RC about people leaving their lights off for up to 72 hours. People with sps were usually doing 48 hours with no ill affects.

i trued the light off thing for 2 days i though it all died but then it came back. do you think it would work if i did 2 days off 2 on gthen 2 off again? oh yea it is a 75gal. my concern w/ the airstone is that dosent it kill the fish? could i use a powerhead w/ air line tied to it or simply having it berak the surface?

The thread about leaving the lights off is a decent one. I've been combating a small amount of algae by turning my lights off for 2 days once every 2 weeks. However I will point out that your source of cyano, probably in a similar way to my algae, is caused by an outside controllable force. Just turning the lights off once in a while won't do much of anything. Just before I turn them out I do a 50% water change in my 75g tank, then 2 days after the lights come on I do another 50% water change. I also clean the fuge and bottom of my sump each time. Basically I'm trying to scrub my tank clean while I'm stunting the algaes growth, that way when the lights come on there will be less nutrients for it to consume.

Also if you are having that big of a problem with cyano I'd have to think that you do not have enough flow in your tank. When I started my tank I had a nice sized canister filter, 900GPH return, and a 600gph power head in my tank for flow. I got some nice sized patches of cyano that would appear and then disappear as they used up the nutrients available. What I did find was that once I got my tank up to about 3,800gph that cyano had no place to take hold and grow. It grows best in dead spots.

I've used the "turn off your lights" method combined with water changes and have been successful.

I personally don't like adding any kind of "cleaning" chemicals to my tank. As mentioned earlier, something is going into your tank that is causing the cyano outbreak. Usually, poor quality water is the culprit of most algea and bacteria outbreaks.
