Fishy Business

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?

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.
