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.

yeah thats the one. is yours still doing ok?

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

Yeah I had waited 48 hours and was ready to do a water change. The clam died sometime 30-48 hours after the chemiclean.

Nothing else had changed in the tank.

The clam was doing really well, it had even attached itself to the rock I had it on. There was sign of new growth.

+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?

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

I think that if you don't have a nutrient problem the main reason for wc is to replenish trace elements, however, they can be dosed.
I am pro wc but that doesn't mean it's necessary.

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

Clams like nitrates. True.

My last battle with cyano was due to a Cbb which I was purposely over feeding my tank so it would eat. Even though I tested water and got zeros across the board I new there were nutrients in there that were feeding the cyano. I wonder if it was leach from the rocks as a few months before I had a ha outbreak from high po4. Even though the water colomn did not test high in those nutrients the rock and sand could be rich

Thanks.

If all fails I'll just do a fowlr and get the clown trigger I've always wanted

I think there is more to the equation than that.

yeah, a large 8" clown trigger, a big harlequin tusk, couple of angels, a sohal tang, couple of lookdowns, would look awesome in a 180

and don't forget to quarantine everything, as it would be sad to see that bunch of fish die in less then 2 days.

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.

Getting Cyano after bio pellets is very common if you don't start gradually and you don't use MB7. The latter is very important to establish beneficial bacteria before starting bio pellets. The beneficial bacteria will out compete the Cyano when consuming the bio pellets or other carbon sources (like vodka).

But have to ask, if you have zero N03 and P04 why are you even using bio pellets?

nutrients is somewhat of a blanket term......lots of people have readings of zero across the board and still have algae and other problems like cyano

This is a good question to which I have a good answer....I am stupid and impulsive! :redface: I was getting into a lot of SPS (I have around 80 SPS in my tank) and I wanted to pre-empt any nutrient problems, since I am heavily stocked and wanted to feed my tank more.

I started very slowly, with 200ml for a 125 gallon tank with a 55 gallon sump, and never had more than 500ml. I dosed bacteria and did everything I was "supposed" to do, but I got hit with cyano anyway. Unfortunately, since my nutrients were so low to begin with, I was stripping my tank to where the corals didn't like it and I couldn't seem to feed the tank enough, so i took them off line.

But I don't want to highjack the thread. I just wanted to give another experience.

i've changed over 100 gallons over the past few days. skimmer still going nuts.

anyone have any better suggestions? i've also been running carbon in a reactor for few days

What I did after I used a cyano cleaner was empty the skimmer cup every time it filled up. I must have sat there emptied it over 20 times before it started to settle down. Just have premixed water ready and replace what is emptied.

My skimmer cup fills up in like 10 seconds with foam

Yep, keep emptying the foam.

hmm ok ill try it, thanks

Have you tried doing a water change?

I had that bad what I did was take out as much as i could and cut off the lights had them on for like 2 hours and had to put a blanket over my tank to make sure no ether light was going in the tank

that has to be a joke:lol:

Marko I did 150 gallon worth of changes. And fineally tied skimmer into Pail. It was filling for a bit then got speratic. It will calm down though.

So keep the skimmer running and overflowing?

yeah you bet

its frustrating but not much else you can do

can you dial it back till it calms down and then dial it up slowly, thats what i did.

careful mandosh...you're walking on thin ice... thats not the problem

In all seriousness, carbon, and running your skimmer without a cup (if you can handle microbubbles) will help calm it down.

Also changing some of the water to physically remove the antibiotics will help but I dont want to go on record suggesting that

Ive changed over 150 gallons so far. Been running the skimmer since yesterday. No improvement

+1...

This is what I had to do after my last dose of chemi pure.
I replaced by volume 75% of tank water over 3 changes and the skimmer wouldnt settle down until then.

any idea why my rocks are turning form a nice purple to a poop brown?

My guess would be diatoms, and that underlying problem that has yet to be figured out....

Steve

diatoms cause by silica?

how do i control it? i've changed over 150 gallons over the course of a few days and used RO/DI water
