cyanobacteria

Hi Folks, Although Cyanobacteria is unwelcome to we aquarists, it's not always the Devil in Disguise :lurking:. Take a look at the following: https://www.newscientist.com/article/2319584-computer-powered-by-colony-of-blue-green-algae-has-run-for-six-months/ One to watch, eh?! JPC

I'm currently holding my own in my battle with the dreaded BGM (Blue Green Menace - aka cyanobacter), but the battle lines have been pretty static for a few weeks. 1. Size of tank in litres. Nominally 305L, but after losses due to substrate and hardscape it holds 240L 2. Age of the set - up...

Hi Everyone, As some of you may know, I took an interest in Cyanobacteria some time ago*. Specifically, how do we keep this Blue-Green Menace under control? Preferably, eliminated. I'm finally homing in on a possible answer. There are, in fact, a few options but some are more workable/practical...

Fellow aquarians, please take a sec to to hear me out about my tank..

 Three weeks ago I cleaned out my office tank – Fluval Flex 57L – which was very neglected since the summer holidays. Heavy cyanobacteria all over the place, removed that all, took out the hardscape, cleaning the tank...

Hi Everyone, Based on a lot of observations and measurements, I'd like to put forward a suggestion/hypothesis. It is this: Perhaps cyanobacteria (BGA) and algae need inorganic phosphate (orthophosphate)/PO4--- in order to grow and survive. But higher plants (macrophytes) can use either...

Hi Everyone, Some of you will know that I have taken an active interest in Cyanobacteria (aka BGA). The reason for this is simple - I have had several infestations of this unwelcome guest in my tanks over the years. So, I tend to avidly read any new research that I find on what I refer to as...

Hi Folks, I'm trying to determine if two trace elements - cobalt and nickel - are required in planted aquaria. Neither of these elements are listed in the index of Ecology of the Planted Aquarium*. Referring to James' Planted Tank**, I see that cobalt is present in both Seachem Flourish and...

Hi Everyone, If you were ever in any doubt about the importance of light spectrum, please take a look at the following: https://link.springer.com/article/10.1007/s11120-018-0561-5 Although the document title gives the impression that blue light and cyanobacteria are being spotlighted (pun...

I had to leave my tank in the hands of someone else during lockdown and upon my return have noticed a big snail population. Can anyone I.D these snails? I'm looking to restart this aquarium and would like to reuse the filter media to kick start the cycling process, does anyone know if reusing...

Hi Everyone, Some of you may have seen a thread I started a few weeks ago: https://www.ukaps.org/forum/threads/cyanobacteria-identification-at-last.60496/ In the process of reading many articles and scientific papers on the subject of Cyanobacteria (aka Cyano), I looked into Cyano's need for...

Hi Folks, Like many other aquarists, I have had cyanobacteria (aka 'BGA') grow in my tanks. And I started reading about this stuff. Of course, I initially thought BGA was algae. Why else would it be known as BGA (Blue-Green Algae)? But I later discovered that it's not an algae at all. It's a...

Hello. I very often use products from ADA in my aquariums (the entire line of soils and fertilizers), but still I can not fully understand how it still works. In my aquariums there is always a powerful filtration, a strong supply of carbon dioxide and strong lighting, clean osmosis, without...

One of my Serpae tetras was showing signs of white spot. I treated last night with Interpet anti white spot plus, now almost all the persistent cyanobacteria that's been a constant problem has gone. Perhaps not surprising given what the treatment is made of, but a welcome side effect! K

Hi, I'm 100% not a chemist, so go easy. There is a persistent cyano problem in my 220ish ltr sumped tank: https://www.ukaps.org/forum/threads/stig-of-the-sump.48558/ It's not overwhelming but it's not nice. I want to address the root cause. Having read here that low nitrate can be an issue, i...

Hello, My tank was going in the right direction but over the last 5 months it's spiralling out of control. I've been battling for months to try and rectify it back to its former glory. I'm not running CO2 and has been a low tank from day one. Cyano is a cruel beast and I just can't get rid of...

Hi - suffering with cyanobacteria in the my hi-tech nano tank. Just done a 3 day black out and it's worked well, but not all gone and it's creeping back. How long could i safely leave the tank blacked out for without killing the plants? (crypts, anubias, AR mini) Also, what's causing it? The...

Hello, I have my first aquascape going for a couple of months now and I am having issues with cyano but as I said I don't have any algae problems. Does the presence of one and not the other tell you anything about the setup, if you know what I mean? I would love to add fish, particularly Dwarf...

Hi, I have an old established 350 litre tank, with a fair amount of plants, and not a lot of fish. Recently, the tank had an outbreak of cyanobacteria, which is quite bad. The glass get almost completely covered by the stuff in three or four days, as do the plants. I read on the internet...

Hi eveyone, This morning I noticed in my tank, 3 types of algae. Black Brush Algae -BBA Blue-green algae (Cyanobacteria) -BGA Green Spot Algae -GSA For the first time, my 255 liter tank is being attacked at a large scale. Usually, the algae problems would be at a selected spot and would go...

Hi all. I recently had some joy treating cyano with the antibiotic Erythromycin. I did this as a last resort after having no joy with increasing nitrates and night time aeration. I also purchased Easy Life's "Blue Exit" for eliminating Cyano. I am a fan of Easylife products but I found this one...

Hello, Got this stuff covering quite alot of my substrate now and could really use some advice on killing it. Tank is 90x30x50cm (LxWxH), with two 39w T5s, Pressurized CO2. Dosing tropica + and liquid carbon daily, plus 50/60% water changes weekly (including thorough substrate cleaning)...
