Thick Green "slime" on water surface... dying fish

Blue Green Algae bacteria

I just got over this in my tank that is almost 1 year old. Its the cyan (sp?) bacteria. Unfortunately, I ended up treating with a round of Erythromycin. My fish also had a bad case of Ich and I lost half my tank. I'm not sure what started first, the bacteria or the Ich, but with both problems going I felt like a mess! My water has always been changed every 1 to 2 weeks with a good syphoning of the substrate. So, after having fish tanks for over 30 years, this was quite a shock and I've never dealt with this before. We just moved to this location from out of state and my guess is the tap water here has more in it (phosphates). In that case, I needed to do something more to help "clean" the tap water beyond the conditioner. So, I bought a UV sterilizer after much online research. I decided to get the Green Killing Machine, just to try the process out at not a huge investment. I do have to say that after 2 days my water has never been this clear and I am very pleased. And, the cyan bacteria has not come back....yet. I hope it doesn't ever again! I am crossing my fingers this is the solution to have a nice tank to watch!! Good luck to you!

I got bga in my tanks before, its one of the most frustrating "algae" to treat. I ended up nuking the tank with maracyn, but that should be a last resort. I had to remove all inhabitants for 2 weeks and had to do a 75% water change followed by 10% daily changes to get rid of the medication, but the BGA has never returned since. Its a pretty thorough nuke.

As for wood, at least when I get it, I dry it in the oven, then I boil it, dry it again, and then soak it in a bucket for over a month (with water changes in the bucket every few days). I've tossed a lot of different woods in my tank from many different sources and have never had any problems. I think the science is that the boiling water + high heat of the oven turns the water into steam and it sterilizes more thoroughly than just boiling. The second boil loosens up the pores and the soak lets any impurities leech out. (I'm not a scientist, just something i think happens from how i treat my wood and experience).

If you look at the first photo that was posted in this thread, to the left, it is pretty clear to see the actual strands of algae at the surface of the water. What we are seeing here is not cyano and it's not BGA. There are thousands of different species of algae out there, each one has it's own specific food sources, light requirements, etc. in order to thrive. While there may be some cyano bacteria involved in this situation, I am not yet seeing any clear indication of that.
The algae seen in the first photo is a very soft hair algae and if you take a finger and skim it through it will pull up, like soft cotton, and bring along anything that is tangled in it. I have dealt with this in my own tanks many times and this particular species tends to be primarily phosphate fed, though it also chokes out plant life near the surface (where there is more light) and feeds from the dying/dead plant matter as well. This type of algae can also contribute to cyano issues as well as a great many other issues in the water chemistry. It can be very difficult to get rid of... but medication is not the way to do it, nor is blocking out the light. Phosphate levels are the first thing to check with a situation like this.

Thanks everyone for the help and advice. Sorry I was not able to give bettery updates as I have been very busy with work.

I do not have a phosphate test, but after water changes every few days then going back to weekly I have yet to see this return.

My main concern was the white "fuz" on my fish. It dissapeared from my tetra after a few days of my last post, but all my cories were lost. im going to continue to treat the wood in hopes I can use it again. Sin, how long and at what heat do you cook it in the oven after a boil?

I am moving to a new apartment Sep 1st. Ill have two weeks to move, so i plan on getting my 20L setup at the new place and moving these fish there. I want to add more sparkling gourami at that time, and Ill also add cories after it is established. I will not be adding panda cories as I have had no luck with them.

Id like to try the wood again at that time, and Ill see if this algea or white fuzz appears again before I move the fish over.

By 20L I am assuming you mean 20g long tank, and not 20 litre? Just want to be clear. What fish are still in this 20g long tank?

Just a caution, from my own experience. If there was white fungus on the wood, and the corys have all died, I would not use that wood no matter how you treat it. I had a branch of what I thought was Mopani but it may have been grapewood or Manzanita (stores may not always label correctly), and the corys were the first fish affected by this fungus. I did what i could to treat the wood, and had it in a fishless tank for 3 months with no issue, but within a few weeks of putting it in a tank with fish, they started dying and I saw the fungus on the back side of the branch. I wouldn't risk the fish.

Good thought on the wood.

Yes a 20long. Now there is only 6 ember tetra and 1 sparkling gourami.

Hey everyone. I know this is old bit I have updates. Things went back to normal for some time, however within the past 6 days everything began to quickly decline.

I woke up one morning and all 6 remaining tetra and the gourami were dead. I wanna say this was last Tuesday. I did my water change the Sunday before. They all had "white fuzz" around them. Now all of my floating salvaina, crypts and Pygmy chain sword are dying off rapidly. My swords were sooo nice. Growing all over the tank, and now 85% percent of the leaves are brown. There is also this white fuzz. My MTS are not coming out hen the lights go out like usual.

I was going to be moving everything to a 20L this time next month. I was hoping to use the plants sand and filter(and fish) but now I'm guessing I'll have to start over. And I don't know when I'll have the funds to buy new plants and fish.

Could anyone help me understand what is going on? I have 4 tanks and this one and my 2.5 have alot of trouble. The only thing I can keep alive in my 2.5 is a betta. All the shrimp and plants died. Except my anabuis, which is yellowing. My 29 and my 5 gallons are having no issues.

This all started in my 10 when I replaced the sponge filter. I let both run side to side for a month before I moved the old one out. That's when there was issues. Unfortunatly it was at the same time I added the wood I stated above.

There may be more bubbles breaking the water surface since this new filter. Could that be it?

Ph is also weird to me. It's about 7.2 in the tap. But my tanks have been lowering. My 29 is like 6.6 but my 10 is yellow on the test. Which is like 6.

And like I said before I do a wc every sunday, sometimes Monday night if I miss Sunday. And does flourish comp on wednesdays. It's a life glo bulb. And temps are at 78.

Sorry I'm very vague and there are alot of grammar issues. My computer broke as well and I'm on my phone. I'm just super stressed at today's situation.

It would seem to me that something very toxic is in the tank, to have killed the fish so quickly, and the plants. If the white fungus from the wood was initially present, that may have been it.

I will hope that Dawn sees this and chimes in, as she will know better than me.

I will just say i know how depressing something like this can be. I have had situations where fish began dying for no obvious reason, and it turned out to be something toxic in a huge chunk of wood [not the fungus, this was different]. I've had fish suddenly dying rapidly from a protozoan introduced with new fish. I've had plants suddenly falling apart for no reason when nothing had changed for months if not years. All one can do is patiently explore the possibles until the culprit is found.

Well like always I want to thank everyone for all the info. However, givin the situation im in I decided to tear the tank down yesterday. My original goal was to migrate this tank to a 20long for more room for sparkling gourami when I move in August, and it seemed like a waste to try and keep the tank going, while not knowing what caused this issue. Now I'll have a fresh start if and when I decide to start the 20long.

The tank was fun, It was my better planted tanks. Watching the chain sword take over and poke out between rocks and wood was great. And I think sparkling gourami are super interesting to watch. I need to find a cheap stand for a 20long and of I can incorporate it into my office when I move I'll start another thread with my build process.

Thanks again.

Well I have no luck. I did a WC in my 2.5today because i missed Monday, and within an hour my betta had the white fuzz on him. I had to go out for a few hours and came back to this. This is exactly how all my other fish looked in my 10. I also added Sylvania from my 5 which has not had issues to my 2.5 and it is already browning after 8 hours, although i have never had luck with this 2.5.



I also messed up somehow and lost the betta in my 5. It’s crazy. He has growths on his sides ( I have another thread on it) and he can only sit at the water line, he cannot swim around the tank too well. I have been nursing him back to health, and i needed to trim the plants today. I somehow lost him. He may have been accidentally flushed, or he jumped and disappeared somehow.

I also moved plants from my 5 to my 29. I really really really hope i didn’t move over any of this fungus. It’s strange the fungus only "activates" after a water change? Do you think i moved things over with my net or something? Is it possible my prime or flourish is bad? If I lose my 29 i think I would lose all hope in this hobby.

I also noticed this type of algae quickly spreading in my 29. I can’t get it off my plants.



Such a bad day
