    Blackwater tank with leaf litter -> Cyano bacteria

    I see, well my son got in in the UK from Amazon and brought it out when he came. That time I had an outbreak in my big cichlid tank so I used all of it, it comes in a really small container. Its still available there, I thought the UK was the same as Europe regarding antibiotics etc...

    Blackwater tank with leaf litter -> Cyano bacteria

    I did use it once and it works with no apparent ill effects, I can’t get it here though.

    Blackwater tank with leaf litter -> Cyano bacteria

    I have tried to read a lot about what causes Cyanobacteria outbreaks, but it seems no one is really sure, it does seem to occur when nitrate is very low, or perhaps when the phosphate to nitrate ratio is high. It is supposed to be worse where there is no water flow, too much light and maybe too...

    Blackwater tank with leaf litter -> Cyano bacteria

    Glutaraldehyde is what the OP is using, “liquid carbon”.

    Blackwater tank with leaf litter -> Cyano bacteria

    This is what I have done, except I only removed the floaters that were affected (they weren’t all affected)), and removed all the leaf litter. The floaters quickly grew back and so far it hasn’t returned. Fingers crossed it won’t when I add more leaves.,,

    Blackwater tank with leaf litter -> Cyano bacteria

    I haven't ever seen chemiclean here, but once a long time ago I got hold of Ultra life blue green stain remover (something like that) and it it worked with one dose, but I have not been able to get it again. It hasn't happened to me in new tanks, rather those that have been long established and...

    Blackwater tank with leaf litter -> Cyano bacteria

    As I mentioned in my other thread I have experienced this issue - similar sized tank 240l (120 x 40 x 50cm) and not actually blackwater but very soft. It has happened a couple of times, when I let the leaf litter build up over time then I start to get Cyanobacteria on the leaf litter and the...

    aggressive solo male sp ortega

    I had a male WC Agassizii that was extremely aggressive, he didn’t kill anything but would not tolerate any other Apistogrammas or small cichlids in the 120cm long tank, he would seek them out and terrorise them even though the tank had plenty of hiding places, I removed them to another tank but...

    Can I make blackwater using my tap water?

    Haha I kind of thought as much!

    Can I make blackwater using my tap water?

    Although actually this is interesting to me as I have experienced this issue, if I let a lot of leaf litter build up over a long time I seem to get cyanobacteria, especially in the roots of the floating plants and on the leaves themselves . Anyway yes, this does probably merit a new thread! I...

    Can I make blackwater using my tap water?

    Ah OK, thanks for this information!

    Can I make blackwater using my tap water?

    OK I certainly do not have a lot of spare money! So I guess using the Sera pH kit for now will at least let me know if the pH is starting to go down, I guess the exact value is not that important...and thanks a lot for the links, I will read through all these carefully later today. But its...

    Can I make blackwater using my tap water?

    I'll check it out, but its a very basic one...

    Can I make blackwater using my tap water?

    Agreed, I have learned this by experience, it doesn't make any difference, or hasn't ever in my tanks, even when I was using almond leave, which did stain the water. Re the pH meter, I do still have it but came with only enough of the chemicals to calibrate it once, and I haven't been able to...

    Can I make blackwater using my tap water?

    I need to get a proper pH meter then, I had one, a cheap one but it was totally useless! Just a quick question, if the tank has a lot of leaf litter etc. does this not help to stabilize the pH? And if so would it work with my leaf litter that is not apparently rich in tannins?

    Can I make blackwater using my tap water?

    Thanks, I do have a spare tank that I could potentially use to prepare water, as long as I don't have to heat it continuously. I'll give it a go anyway, nothing to lose.

    Can I make blackwater using my tap water?

    Just for comparison I tested the water in the big tank where the pike cichlids are currently. It s only slightly different: GH 2 KH 1 (1st drop blue, second yellow) pH 6.6-6.8 (can't tell, Azoo), 6.5 Sera. TDS 36

    Can I make blackwater using my tap water?

    As I mentioned in another thread, I want to try to breed my dwarf pike cichlids, but I am pretty sure I will need to have real blackwater conditions, as they have not showed any signs of breeding so far. But my water is already very soft. I hadn't measure the parameters for a long time but...

    How to go about trying to breed my dwarf pike cichlids

    I have a pair, well a male and a female anyway, in my large cichlid tank, they are I think Wallaciia cf nothopthalmus sp Orinoco. I have had them well over a year now, I did have another female but unfortunately she died not long ago. I was speaking to someone else who also bought some at the...

    Is 48inchx16inch large enough for two groups of ortegai?

    Just reading through this thread, which I missed before. As I understood it these fish are not being farmed as such, just collected, moved and stocked in a more convenient location close to Iquitos where they will be easier and less expensive to capture. So they are being caught in the wild...
