Cannot get rid of cyano!

[MarkoD]

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.....

So it only effects one clam and nothing else?

you had cyano!.....that means excess nutrients!.....

Maybe I'm confused. I thought clams take in neutrients to grow.

And why would excess neutrients effect one clam negatively but not the others?
Some of my corals seem to have benefited in the last month while I've had cyano

I think there is more to the equation than that.

Actually, not at all. I have NEVER had P04 or N03 readings n my tank - I mean NEVER! Not since day one of the tank. I have incredible flow, new bulbs, I under feed my tank, exceptional filtration, there is NO way I should have cyano, yet, it grows in the darkest parts of my tank, on powerheads and in front of the returns of my closed loop. Cyano is a bacteria, not an algae. There are so many different forms and it's next to impossible to know what is feeding it sometimes.

Of course, you need to be sure you do not have excess nutrients. Agreed. But I got Cyano after trying bio pellets and I can't get rid of it, despite trying everything that has been suggested. Even Red Slime Remover. Something is feeding it. Just can't figure out what. The funny thing is, my tank, otherwise is all but perfect. Corals are happy, fish are happy, parameters are spot on and it only grows on the rocks, never the sand. Go figure.

I know you say wc are not realistic for you. And I would understand if fowlr. But it may help just to do a monthly change.
I know you dose the essential and everything looks great but even once a month will only take a hour of your time.

I dose cal alk mag. And prodibio. I did try the route of no wc. But wasn't happy with growth rates in my tank.
I do a biweekly change of 50 gallons which I do while cleaning tank. I believe it does wonders as my cheato nor mangroves will grow. I started with a base ball size chunk and 6 months later it's the same size.
Wc never did help with my cyano problems but after using cemiclean I switched to RODI and cut feedings down to half. My tank hasn't seen cyano since and the wc seem to keep my tank cleaner
