Cali Kid Corals

Dealing with lyngbya

@MichaelB is there any desirable photosynthetic stuff in your 210 right now? Could you just blackout the tank for a week or two to get rid of it?

Edit: nm saw your journal. Moving the coral and blacking out the tank still could be an option?

This cyano doesn't need any light to thrive. It can grow inside pipes etc
 
Update day two:

20260404_144152.jpg

Reef flux- no noticeable change since yesterday

Chemi clean- the mass seems slightly less dense and can observe some separation but no actual breakdown.

Azithromycin - it seems thinner than yesterday more indivual strands are visible

Peroxide- the water seems slightly more murky after adding yet another dose today. I must admit I've likey lost the hold over the salinity variable here by adding the 3 different doses of peroxide. So it's important to note I doubt the salinity is still at or just above 0.025 all the containers started at. Possibly a fair bit lower.

Control - it seems just a held together as day one. No signs of growth and zero signs of any degradation. Water is pretty clean compared to the tank so it's likely a strong inhibitor of growth.

The 210gallon tank. I didn't take a picture today as glass is dirty and would be challenging to show what I saw in person with a picture.

It's hard to say for certain. But most of this stuff just seems way thinner than it did yesterday. At the same time I noticed more strands of it clinging to the powerheads. Likey some came detached from rocks or substrate and was captured by the mp40s.

There is one rock structures that actually doesn't appear to have any of this stuff on it any longer. While another rock still has 2 of the denses baseball sized patches in the entire tank.

I see effects, though nothing to the point I'm confident this will be tbe treatment that actually works.

The effects observed thus far with Azithromycin exceed any of the effects from all previous in tank treatments so there is slim hope developing that it may work fingers crossed.

So a interesting update.

I saw the 210gallon tank today and was kinda like screw the experiment for today. I maybe share a update on the experiment tomorrow.

These pictures are from 2 hours ago. If you scroll back slightly you can see the pictures from a few days ago.

It's actually 95% just gone. There is some stuck to wave makers still. And a few tiny patches in 2-3 other places and even those parts are starting to turn pale (similar to what you expect from using reefflux on gha or bryopsis)

I actually think the stuff is actually working.

I won't declare victory until time has passed and I don't see it returning over time. Yet this is extremely encouraging and a possible solution when all other attempts did nothing so far.

These are two shots of the nem tank, where I screwed up and spread that stuff to this tank as well. 2 month ago this tank was flawless not a speck of the stuff in sight. Than you can see how fast it takes off once it has a foothold.

I added a half dose of Azithromycin to this tank. So expecting results may not be as fast. Hard to say with it being much smaller water volume and a aio tank. Fish are present in this tank so I cut the dose down out of caution.
 
So happy to report in the 210gallon tank. This stuff appears 100% gone. Even from the wave makers.

I did mention doing half of recommended dose in the nem tank.

So far it seems thinner but very much still present. The nems have shrunken considerable. They were over 3-4 inches. Some over 7 inches. When this stuff appeared they shrunk to 2 inches. Azithromycin they have become a inch in size. As far as fish I see no effects on them or clean up crew. The nems themselves look healthy in terms of color and tips.

Maybe this stuff is releasing something as it dies or the antibiotic is making them unhappy.
 
Day 6 of Azithromycin in nem tank. Only used half the dose so it's effect is within expectations. Main tank at full dose took 4 days.

Maybe half dose will take 8??.

Compared to the pics above shared Monday. It's clearly very thin, it's changed to a higher color. Overall it seems like it's on its way out.

If the treatment works in this tank as well it would be two back to back instances of this actually wiping it out at a half dose and full dose.

Excuse the dirty glass. I only have one flipper glass cleaner. After the ich in the 210 I'm not longer willing to risk sharing the cleaner between tanks as I use to.
