    Got some plants from Andre (thanks Andre! :)) from a tank invested with Cladophora algae. I've treated the plants with 1 part to 20 solution of bleach to water for 2 minutes, followed by a thorough rinse in tap water, then a soak in water with dechlorinator for about an hour, another rinse, and then placed in a container with tank water and seachem excell at higher than usual dose. Its been about 3 days now and the cladophora is showing no signs of dying. Should I leave it for longer, or treat with a higher dose of bleach? The plants are still OK, but I don't want to kill them either.

    Hi Neil

    I am glad you are doing this experiment. As soon as I have more time I am going to try to eradicate the clado from that tank.

    What has worked for me is to move some of the infected plants to the emersed setup. They have come back nicely and I am going to try the bleach dip method + quarenteen before I put them back into any of my tanks.

    Bleach doesnt work in my experience, I will be trying some of the professors algae medications next week and will let you guys know how it goes..

    The bleach doesn't seem to have worked, nor did the Excell. Last option would be to use Prof. Bellstedt's algae medication as mentioned by Philfarm, any update on that?

    Cursed be Clado. What I originally thought to have been fuzz algae growing in between my Fissidens on wood, turned out to be Clado. I initially couldn't really tell but, when I got home last month it was pretty (or not so pretty) evident. It's now grown all over the wood and smothering the Fissidens. Chemical warfare is out of the question for me as I can't afford to loose the Fissidens. I'm now also going the emersed route. Will keep you guys updated.

    How would you ensure that with emersed growth the clado doesn't also stick around? Surely if the plants survive, the clado (or even worst, the spores) might survive, only to start growing again when submerged?

    I've probably had a small amount of Clado in my tank for quite some time. The only reason it took over now is due to neglect.

    My idea is to harvest as much of the emersed grown Fissidens as possible, put it in quarantine and then start experimenting with the wood and whats left on it. Time will tell, but I don't expect to completely eradicate it from the wood unless I chuck it outside to dry in the sun. The first experiment will be temperature, apparently Clado do not grow in temps above 30 degrees, I expect the Fissidens to take a huge knock too though.

    It was from a scientific paper someone posted on APC.

    I'll try and find the post later.

    i read that - its for marine clado, but as you say it is definitely worth experimenting.

    clado is the devil...

    I hate it! I hate it! I HATE IT!

    Chemical holocast is my last resort, think i'll stop by dirks lab this afternoon and c what the options are..

    RC I also have clado on the same log as my fissedens but it doesnt seem to be bothering it yet!
    What it is "bothering" is my HC tank and I cant go the emmersed route because its full of wrigglers :(

    Where do you guys think clado suddenly appeared from 2 become a problem for a whole lot of different people?

    It came in with the AquaH20 shipment a while ago :(

    Apparently Hydrogen Peroxide might also be an option to kill this stuff. I am going to try a UV filter and lots of ciculation and see if that works.

    ...and were then possibly further spread around by us giving away clippings.

    Well those are the experts ::)

    But in my experience clado is an atypical algae that grows more like a plant than algae and what ever I do to the algae is felt harder by some sensitive plants like HC and Helferi. What Barr is saying is the typical treat the cause not the problem (whereas normally I would agree) he might as well tell me the same thing when I want to trim my anubias.. :mad:

    Anyone else had any luck yet?

    I have some Cladophora despite running a UV light. At the moment I remove it manually when doing water changes.
