repeating Chemiclean treatment

[Delphinus]

TBH I'm a little surprised you felt the need to do a second treatment so soon. Unless I'm mistaken as to when you did round #1. Honestly, cyano being one of the most successful lifeforms on the planet (here long before us, will be here long after us I'm sure), it's going to take some time to recede, but it almost 100% always does after a treatment - just give it some time.

Really the only reason I did a second one right away was because I've done a chemiclean treatment once before on this tank when the cyano issue was much less severe, and the cyan began to return in the same spot the same week, leading me to believe that I didn't get it all in 48 hours. I wanted to really make sure it was dead. It was probably overkill, but nothing seems the worse for wear today. All the corals that were shrivelled are looking normal now.

It's not that the cyano was ever really *that* bad, but I'm a neurotic perfectionist, and I didn't like the trajectory things seemed to be on. Someone standing in front of the tank, at a glance, would only have noticed a small patch of it in one spot on the sand, but when you got up close and started looking at the rocks, you started to realize that there was way more of it than it at first seemed. Also, anywhere that my corals would touch and fight, there'd be thick tufts of it, which seemed to be preventing the tissue from being able to heal after I trimmed back offending branches.

On a side note, maybe it's just a placebo effect, but when I looked up from my computer a few minutes ago I thought "hot diggity that water is clear!" It's like practically glittering. It's making me think that I should run GAC more often, this is only the second or third time I've ever put it in.

That clear water could be from the MB7. I have noticed many times how crystal clear my water became about an hour after adding it. Especially, after cleaning, or my goby was hyper active in the sand bed. Plus you might see more detritus and mulm disappearing, if you have any somewhere.

Do you notice a hazy white film on the glass after dosing it? Not like the normal brownish slime algae, but a very subtle white haze that comes off easily with a mag float?

No, I do not. But my doses are very low at this point in time. And it's been almost 2 years now, since any heavy dosing. But don't remember that.

How/where do you dose it? I just pour mine straight in to the DT (and never shut off my skimmer).

If you are getting a white haze, your bacteria may still not be in balance. See if it still does that after 2 weeks, and you reduce your dosing amount.

Yesterday it was 50% in the BP reactor, so 50% wasn't technically going in to the tank water. The other 50% was just in to the display. I set up a feed cycle on my Apex that shuts only the skimmer down for 4 hours so I can have it come back on automatically. I didn't notice the white haze when I started dosing MB7 in November, just this morning a couple of hours after I shut the skimmer down and dosed. Today I put 50% in the display, and 50% in the chamber of my sump that has a bunch of extra rock and lots of cryptic sponges.
