Cannot get rid of cyano!

[Nano]

Hey Marko, I havent read the entire thread but most of it, Have you tried a black out period at all? I have heard that it helps as well, or atleast shortening you light cycle. I could be wrong though. Hope the battle goes well. Cyano is an ugly "b"

I tried the blackout, 4 days no light except 1/2 hour a day ambient light to feed the fish, cyano was gone but quickly returned a couple days later and seemed to spread even faster.
Cyano is probably the most resilient, opportunistic thing on this planet and normally we can keep it in check but sometimes something happens and you get a plague.
I am totally against chemical treatments but I have to thank chemiclean, I was getting ready to quit.

Blackout works great. Has to be totally blacked out though, not even a peep of light. I conquered Dino's with a complete blackout for 5days. Covered the whole tank with my motorcycle cover. Also, when I lighted up, replaced fixture with all new bulbs.

so i got home from work yesterday, ready to do a water change and my nicests, most expensive clam is dead. retracted and gaping.
it was looking good the night before


other 3 clams looked fine and are still fine now.

I highly doubt it was from the cemi clean. I have 8 clams and cemiclean has never bothered them.
I'm guessing your clam that died is the blue maxima from Steve. I also have one.
Sorry for loss

Sorry to hear Marco

I have to believe you had some underlying condition in your tank, something was sick, infected, dieing or something and that is what was fueling your cyano, chemiclean is an oxidizer so it would probably kill something that was sick or dieing.

+1......or it could be that perhaps 14 months with minimal water changes are finally catching up with the system.....

yeah thats the one. is yours still doing ok?

[Proteus]

Yeah it's good but highly irritable. That's Alot of money to loose. A ****ty way to wake on a sat

But cal is right. The cemi clean will work like hydrogen peroxide does on a wound. Oxidizing dead flesh. but if you clam was good yesterday it seems odd to die in one day.

I never read the thread completely as I couldn't be bothered with the arguments but was that your first wc since the cemiclean. When ever I was used that product. It was about 150 gal worth of changing. On a 250 g system
