Erythromycin for Cyanobacteria

I agree with @DoubleDutch. If you have no livestock in there and therefore arent feeding its probably due to not having enough nitrates or phosphates

 

If you add CO2, you don't need excel.
It is different carbon-source (Gluth) when someone doesn't add CO2.

No Cory no glory

 

The micro fish probably dont produce enough waste, especially if your tank is as heavily planted as the picture you posted. Is it the flourish fertilizer that you are dosing? Excel is a liquid carbon addiditive. Flourish does have a micro/N/P/K fertiziler range as well.

 

This is it

Sorry. My bad. Its Flourish comrehensive

Mmmm that should do the job then.

Since when are you adding this ?

No Cory no glory

 

The strange thing is when I look back, I had that issue with no fish. Once I got fish, I stopped dosing EI and left it as it is.

Plants grew well, very little algae and just weekly maintenance.

Maybe you should consider getting cories - I fed them on bloodworm, bbs and freeze dried tubifex. All that may have contributed to the plants doing very well.

 

Sometimes a rip and replace is best .. esp if the thank was exposed to many different chemical treatments and the balance is totally out of whack ... problem in a tank that has crashed - you have no clue what is now absorbed in what. I had this on D-tank .... a few years back - in the end remove the substrate - and the wood. leave the wood in the sun for a few months then start cycling it back. I know it sucks but starting a simple clean tank is way more rewarding than trying to remember why things went wrong.


If you do decide to do the rip and replace - consider a citric acid bath for the plants before you add them back in the tank ... this will help to clean things up from a plant view, hardscape also needs some refresh. Dump the substrate.

- to a large degree I am doing this on the 7 year old ADA substrate that I have finally replaced on the 550 ... it also give me time to experiment with a different substrate again so win win ..

Later Ferdie

PS keep us posted and update your tank thread more regularly with pics - trying to figure this out a year later is almost impossible.

 

Started adding it about a month ago.

 

How many should i get for a 60 liter tank? I'm considering adding some fish, but I'm going to do just a few in the beginning in case I kill them.

 

I'm going to give it one last try. with all the info gathered here. Two months. And if it doesnt get better, i will rip out and start again. I have a really nice piece of wood similar to this one, but smaller that I'm dying to put in some water...Would be sad to see this setup die completely though.

 

To be honest, with cories, you need a small group of 5 or more. The tank that I had was around 84L. I raised the fry in a 60L tank.

For a tank like yours, I would actually go for smaller fish like glowlight tetras, they will really look nice on a green background of plants. My godfather has a small tank full of tetras and danios and they do well but he has two filters, he said two because of the bioload mass that the filters has to handle to keep the water in good condition. He also has one angel as well. I think his choice was poorly made when he got fish for that tank. BUT however the point is he barely has any algae, very little BBA and no cyanobacteria. He doesn't even feed the plants either, just the fish only.

IF I remember correctly, he had 2 glowlight tetras, 2 neon tetras, 1 angel fish, and about 3 danios.

 

Alright then. Off to Aqua Empire after work.

 

Why not try this, I heard this mentioned on the Aquarium Co-op channel.

Remove the rocks if you can the spray them with a bit of hydrogen peroxide.
Apparently the algea will turn red. Then you can scrub it off easily.

I personally have not yet tried the above, but I do intend to try it next time I need to remove stuborn algea from hardscapes. I have in the past however taken out rocks before and left them in the sun for around a week and then put them back. Not ideal but it does work.

What I have recently discovered through is that the Malaysian trumpet snail is ideal to deal with these types of blooms especially in the gravel/sand area. They grow slowly and mostly keep out of site as they bury them selves in the substrate so your tank will not be overloaded with snails, like with the common pond snail.

I have quite a few tanks with these guys in and I am happy with the results.

No rocks. Just a big stump with substrate in the bottom. I've been doing H2O2 aplenty in this tank and it does seem to work, but as soon as I've done one spot, it flares up elsewhere. Need to treat the cause, as stated previously in this thread.

 

Sorry once I read through the entire thread I saw you mentioned H2O2.

What filtration are you running?

I recently had a big problem on my 110Litre community tank that turned completely green almost over night. I had only a aqua clear 110 on it and thought it wod handle. I did water changes and lots of other things and battled with it for about 14 days. Nothing worked and it just got worse. I was worried how this would eventually effect the fish, so I stuck a Tetra canister 1200 on it, solved the problem and watet is super crystal clear all plants and fish survived.

Your problem sounds like an algae bloom. Nothing like cyanobacteria, which is ten times worse than the average algae growth you usually get.

 

Things are starting to look up! Thanks to all for your inputs.
I think we’re getting there.

Funnily enough I now have cyano bacteria in 2 of my tanks - my sawbwa tank which is quite heavily planted and in my breeding setup. What both of them have in common - poor flow and 0 nitrates. So now I am dosing KNO3 and have increased the flow in the sawbwa tank. In my fry setup I am not increasing any flow as the fry are tiny and prefer as little flow as possible. Will probably end up peroxiding my fry set up once all the fry have been grown and moved out but before I add the next batch of eggs.

PS - your tank is looking much better. Keep it going
