I had it in my little few year old greenbin tank a few months ago.. It's just a 25 litre tank with a 5 or 6 different sp. off mosses including fissidens, snails and sherry shrimps and some leftover plant cuttings and some experimental planting. It's relatively well lit and stand next to an east side window receiving daylight as well. I never fertilize it via water column, i put in some fert tabs for some plants that seem to need it. Everything in there except the mosses are mainly temporary, it changes constantly and looks completely different every few months or even weeks. Anyway, after
experimentaly chaging and intensifying the light setup and seemingly neglecting it a bit for a few weeks after that, i had a massive clado outbreak. I just gave it the same and no extra attention as always after that change..
I have no idea if this outbreak correlates with the extra light intensity, could be coincidence or not.. Make a guess!? In a way it could be a yes.

Anyway, after cleaning the HOB filter and soaking the case in bleach (not the media) to kill any algae spore in there, just made it brandnew clean..Taking out as much clado as possible manualy from the tank , spot treat a bit with peroxyde and after that draining the tank 80%, giving the glass a good rub and spray all the glass with peroxyde, Than filling the tank back up with clean water. Did a 4 day 100% blackout and after that an 80% water change again. After this all clado still in the tank was grey and dead.
Not seen any clado back since and also didn't change the light setup or anything else.. But it's getting winter so it gets less intense daylight. Still no idea if light correlates to this in my case. Could be coincidence again.. But a good rub, a mild peroxyde treat and a 4 day blackout, killed off the clado. Must say it also killed of a rather sensitive Nymphaea i was experimenting on this tank. But the rest didn't mind. It was my first clado outbreak in this little tank and till now the last..
I have a hunch it is Light intensity versus plantgrowth versus fertilization, if this chain is out of sync and if it favors clado, you're busted, it takes over like in few weeks time.. There are longer term methods to figur it out and get rid of it, but clado is a real bugger. Because i was little late and it was turned to a realy bad clado case i choose for the desperate method as above and it did a hell of a job. Little tank is back on track again as it always was..
