Thank you Roger, I appreciate it. Do you think the performance of the skimmer is significantly increased the the new cup design? I don't want to be a bother to you, and especially not if you don't think it will have much effect. Also do you think this will have any effect on the plankton friendliness of the skimmer, because right now I'm really impressed with the amount of microlife I have, including a self sustaining population of what I guess are some kind of rotifer swimming around in my refugium, I wouldn't want to spoil that. Also, how tall is the new cup if you think it's worth getting it because i have about 16" of overhead space right now above the skimmer, certainly it's not taller than that?? Thanks again.
