Aqua C Remora is good. I just don't like the internal pumps in my tank, thats the only thing i have against them.
20 high or long? And is your tank pushed up against the back of the stand? You should no this if you want the eshopps because it is quite tall (23"). My tank is 12" tall and if i don't have the back of the tank right up against the side of my stand the skimmer won't be able to hang on your tank. So what im saying is if you have the 20 long you will need to have 16" straight down from the back of your tank. What i did was cut out a part of my stand for it to hang properly.
