Rowing is incredibly good for your entire body as it's a great cardio workout as well as an excellent workout for your muscles. It also not only involves just your arms but also your legs as well and there aren't too many cardio workouts out there that incorporate both like rowing does as well as giving you a muscle workout, it's literally one of the best workouts you can give yourself.
It will only have an adverse affect if the ergo will put you into a caloric deficit and your body starts to burn muscle for energy. If you have have on you fat will burn first and all you will be doing is slimming, but if you are lean then you will need to ensure you are consuming some serious calories prior to training.Ok so if I encorporate a rowing session into my weights sessions - will it work against my aim to build muscle mass?

You may be over training - this may happen if you are training every day. If your exercise is rigorous, try to have a rest period so that you have a break day between your training sessions.
In reality your legs should feel stronger, since rowing mostly train the legs. It is either you are not rowing properly (unlikely because either way your legs would still dominate), or that you are over trained.
