I'm not sure, I've never got rid of it, but it has never gone mad. It doesn't like really soft water, or very low nutrients, and in some of my tanks it has <"lost the surface battle to Utricularia gibba............">Is it possible to eradicate Riccia from a tank without killing everything else? The stuff is a menace.
Dose Glutaldehyde at 2 ppm (Seachem Excel recommended 5x dosage after WC) daily for a week.
did you do a WC daily ?
Worth considering just take a few samples off mosses out I like first
It can take quite a while and you have to be on top of it regularly... In the end, you win... Persistence pays off..
I know this is a <"path of least resistance"> answer, but how about just skimming of the bits of Riccia that reach the surface?I have tried, however with may carpet being dense and 50cm below water it is very time consuming
I have this problem, but the other way around. I spent about an hour last night, carefully removing the poor, spindly, individual fronds of Riccia from the spare floating plants (before I throw them in the pond) and repatriating the Riccia to the tank. I know this is a <"path of least resistance"> answer, but how about just skimming of the bits of Riccia that reach the surface?
After that take the broad brush approach and only ever look at your carpet from a distance, it will be lovely, lush and green and you won't be able to see all the Riccia in it.
Use the initial dosage, that is, 1 capful (5ml) for every 40 L (10 US gal) every day for a week. Since SeaChem Excel has 1.5% Glutaraldehyde, it is equivalent to 2 ppm Glut. I use Metricide 14 that contains 2.6% Glut, and the equivalent dosage in proportional calculation is 2.9 ml per 40 L.@tiger15
Just for clarification - seachem 'Excel' advise

Which did you dose-
1. Initial '5ml/40l x5' after WC then '5ml/40l x5' per day for rest of week
2. Initial '5ml/40l x5' after WC then '5ml/200l x5' per day for rest of week
3. Initial '5ml/200l x5' after WC then '5ml/200l x5' per day for rest of week
